I initially installed the Microsoft Visual Studio Express 2013 for Web on my desktop. My desktop runs Windows 8.1 with internet explorer 11. It ran fine until the license expired after the first 30 days. I tried to sign in to renew the license, however after clicking the 'sign in' button I get an error dialog. The dialog states 'Browser is security restricted or javaScript is disabled. I have no other option but to close and exit Visual Studio.
I went to the online forums for Microsoft. There were discussions and suggestions on how to fix the error. I tried lowering the settings for the security tab in internet explorer. I have validated the option for scripting is enabled. I have also added https://*.visualstudio.com to the trusted sites tab. Other users on the forum have tried the same suggestions and have not succeeded in signing into the visual studio application.
I had exactly the same problem, here is what I did:
a) Go in IE, click on settings wheel then Internet Options and Security tab.
b) Click on Custom level button (make sure you select Internet zone).
c) In Security Settings window, under Scripting I set Enabled for Active scripting.
After that Sign In should work. Even though Chrome is default browser, it seems that VS uses IE for sign in process.
Hope this helps!
There is another issue people are running into that is a bug with the login dialog. The login dialog is using a Web Browser control to login the user. By default it loads up "about:blank" as the URI. It then proceeds to try to execute some JavaScript (just ";") to verify it has permissions to do so. On some machines this is problematic because "about:blank" has been mapped to zone 0, or the Local Machine zone. When the JavaScript is executed MSHTML will check the zone of the URI and then the policy for executing scripts. By default the Local Machine zone is locked down, and all script executions result in a Query policy. What this means is if you're running in immersion mode (aka in Internet Explorer) you will get a message box asking if you want to execute the script. However, the Web Browser control used by VS 2013's "Sign In" dialog doesn't run MSHTML code in immersion mode, so the Query policy effectively equates to a Disallow policy. The bug here is someone in VS assumed "about:blank" resolves to the Internet zone, and when it resolves to the Local Computer zone you get this behavior.
The workaround is to remove "about:blank" zone mapping. Point regedit to this key:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains]
Remove the "blank" key.
Alternatively you can change the Local Machine Lockdown policy for executing scripts. The reg key for that is:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Lockdown_Zones\0]
Set the "1400" DWORD value to 0.
There are many sites you need to list in your Trusted Sites. Following the trace of what the stupid, stupid login script does:
https://.visualstudio.com
https://app.vssps.visualstudio.com
https://.accesscontrol.windows.net
https://auth.gfx.ms
https://login.live.com
Only then was I able to log on to my FREE software.
Hi this is Albert from Microsoft. Just want to let you all know that this issue has been fixed in the upcoming Update 2 for Visual Studio 2013. Thanks for your patience while we figured this one out :)
Same problem "Browser is security restricted or JavaScript is disabled" here but the solution from #jic didn't work for me..
If you can and it is convenient for you this is a solution which worked for me:
I have created a new user/profile on my PC and for this user it was just working fine.
Before this action I have tried to make an user account which had this problem as:
Power user - didn't work
Administrator - didn't work as well
So the last solution in my case was a brand new user on the PC..
Here's what worked for me.
Open Control Panel, Internet Options.
First, I clicked the Security tab and turned security the security for the Internet zone to its minimum.
Next, click the Privacy tab, then click Advanced. Choose "Accept" for both types of cookies.
Of course you can change these all back after extending your VS trial.
you must change secure settings of iexplore for admin account. If logon by other account, you must start iexplore under admin account or logon under admin account, because you will get license after admin account.
Click on Start --> Run --> type cmd and click on OK.
Command Prompt will be opened. Then enter this command.
ipconfig /flushdns
and press Enter.
Now try to access https://app.vssps.visualstudio.com/Profile/View
It worked for me...
As I can not add a comment yet to the answer of CBGraham, I've to add this note over here:
The solution described from CBGraham worked for me (Thanks Graham). I had to add an additional link:
https://account.live.com
Then I opened the IE and tried to login to a Microsoft site. I left the IE window open and just clicked once again on the VS to login. Then it worked for me. Even with strong restrictions on the IE settings. While I'm surprised why someone should set down his security settings, just to register VS.
I want to debug my application by VS but when the application should run, it should have url like: http:localtesting.com instead of localhost. I already have localtesting.com in my host file so directly putting that url in my browser opens my IIS default directory page. How can I make my VS to run on that url while debugging? Where should I put that url?
Edit:
Putting the url in custom web server textbox and running the solution I am getting :
Set it to "Use Custom Web Server" and put your URL into that box.
Edit: 'The unable to debug..' error message is probably a separate issue. Can you debug a brand new site that you can create just to test?
A few things can cause that error. For example, the URL Rewrite module: Unable to start debugging on the web server. Could not start ASP.NET debugging VS 2010, II7, Win 7 x64
As #SteveHobbs said, set it to "Use Custom Web Server and put your URL into that box. Just underneath that section, there should be another section labelled "Debuggers".
Put a tick into the checkbox next to ASP.NET and save the properties.
When you want to debug, go to the debug menu within VS and choose "Attach to Process...".
If you are using IIS, look for the process called 'w3wp.exe' and choose that. After a bit of crunching, perform whatever actions you need on your web app and you will see the debugger land on your breakpoints and so on.
I'm using CodedUI on IE8, and get this error message:
Stop running this script?
A script on this page is causing your web browser to run slowly.
If it continues to run, your computer might become unresponsive.
I've read some forums and did the following: Tools > Internet Options > Advanced tab > Browsing
Check the "Disable script debugging (Internet Explorer) checkbox
Check the "Disable script debugging (Other) checkbox
Uncheck the "Display a notification about every script error" checkbox
and this message still appears...
Can anyone assist me here?
IE has a registry setting for that
Error message: "A script on this page is causing Internet Explorer to run slowly"
but that requires you so change the registry on each client machine and for each user.
It will however allow you script to run so you can profile it and find out whats causing the delay.
Also look at this SO question How to mimic effects of MaxScriptStatements (i.e. prevent “A script on this page is causing Internet Explorer to run slowly”) without changing the registry?
I am working on an MVC project- for changing the default browser I added a web form and by right-clicking, I changed the default browser, but now when I tried to run the MVC app it showing an error pop up."You need to specify the full path to an executable file"
Can anyone help me to fix it?
Right click on Project file ( .csproj) and select Properties.
Go to the Web tab.
Choose specific page radio button ( its The start external program causing the problem).
I did the same default browser trick that you did and ended up with the same error every time I tried to run the app.
I tried:
Using 'Browse With...' and manually pointing to the exe of one of the browsers
No joy
running devenv /resetsettings
No joy
Installing WoVS Default Browser Switcher and switching between browsers
No Joy
In the project properties changing to 'Don't open a page. Wait for a request from an external application' then changing back to 'Specific Page'
No more error!
As far as I know the last step is all that was needed but just in case a previous step had a side effect I thought I'd list them all.
Hope that fixes your problem, it's a truly awful error.
I cannot start my website from Visual Studio 2010 anymore.
For a few days I cannot start my project in a web browser using F5. When I open my web application directly by typing the same url 'http://localhost/Default.aspx' everthing works fine.
When I run the project (F5) a new webbrowser starts, but after a few seconds it is stuck and Visual Studio gives an error dialog:
Microsoft Visual Studio
Unable to start program 'http://localhost/Default.aspx'.
OK
When I run the project in release mode it gives an extra error:
Microsoft Visual Studio
The following module was built either with optimizations enabled or without debug information:
C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\6552bec6\694bce32\assembly\dl3\8c9bd8d8\fb1d75cb_af26cc01\[name].Presentation.DLL
To debug this module, change its project build configuration to Debug mode. To suppress this message, disable the 'Warn if no user code on launch' debugger option.
OK
I have already repaired, removed and reinstalled Visual Studio 2010, I've tried using different browsers (including Chrome and Firefox), used different aspnet_regiis.exe options, etc. etc.
Nothing helps, and yeah now I'm stuck pulling hair out of my head ...
Anyone any idea how to solve this?
Does it work if you start it with [CTRL]+[F5] which runs without the debugger?
If so, then you have an issue with the debugger auto-attaching to the web server. I would check that debugging is enabled for your web project - a warning that usually crops up automatically from VS when it detects that a project is not built in Debug mode.
This is not as simple as switching the project configuration over to Release, because the DLL that the debugger is moaning about is one of the dynamically generated ones originated by Asp.Net itself.
Typically you should have, in your web.config:
<configuration>
<system.web>
<compilation debug="true" >
</compilation
<system.web>
<configuration>
(Along with any other stuff in <configuration> and <system.web> nodes).
There's also the possibility that Asp.Net debugging is not, for some reason, enabled.
Check out this msdn article on debugging asp.net applications in VS2010 for more information.
Note that if this is VS010 express, then you won't be able to debug - as confirmed by the aforementioned link; but since you way it used to work then I guess that's not your problem.
Update
Since that hasn't worked - you can try emptying the Temporary ASP.Net files folder. Easiest first is to do an iisreset. Then navigate to C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files and delete everything in it. I've had issues in the past where the Asp.Net binaries don't get refreshed and so when I'm debugging it moans that the files are out of date.
Change the View Browser to another browser. Run the view in browser or debug, then change back to original browser should work after that.
Had same problem, answer for me was to remove Avast Free AV. Everything worked for a year with avast free up until a week or so ago, uninstalling it fixed the problem.
I had this exact problem with Visual Studio 2008. The solution was to set the default web browser that VS uses to a real browser (e.g. IE) and not the "Internal Web Browser".
Right click on an ASPX file in your project and select "Browser With...". This lets you select the default browser to use when you select the "View in Browser" option and for when you debug/run the app (this is key).
Select your favourite browser (i.e "Internet Explorer") and click on "Set as Default". Do not pick "Internal Web Browser".
Debug away! Your app should come up in your browser now and debug as normal.
the solutions for me is to test with 127.0.0.1 in place of localhost. and all goes well for.
so the problem come from the host resolution name, to solve it please proceed like :
open cmd and then tape : %systemroot%\System32\drivers\etc\
open hosts file with notepad and the look for localhost ligne(you'll find 0.0.0.0 befor it )
change the 0.0.0.0 with 127.0.0.1 at all lignes with localhost .
I solved in this way:
Right click on a aspx page
Browse with set internal browser as default
Remove the previous default browser
Add %programfiles(x86)%\internet Explorer\iexplore.exe
Set this choice as default
For me I just did a Build /ReBuild on the project level and it started working!!!
I had the same problem. When I debug my code it says:
Unable to start program 'C:\homework.exe'. this system cannot find the file specified."
I'm using Microsoft Visual C++ 2010 Express but when I made a new project by the following steps:
Open C++:
Press new project
Press win32
Press win32 Console Application
Rename it
Click next
make sure: that the application type is console application
additional options: empty project*
Press Ctrl+Shift+A
In Visual C++/Code section press C++ File (.cpp)
rename it and press add
It works fine with for me now.
Please set your page name e.g Default.aspx revert to parent in IIS configuration
I'll share my experience with this same problem. This is not a solution, but someone may be able to figure out the problem from my particular experience.
I've been having this same problem for a few weeks now. (I don't know what changed on my system.) I do not run as local admin, because we are not allowed to have admin privileges on our PCs where I work.
Until today, I could expect F5 (Start Debugging) to start up a new local VS web server, open an IE window, and then issue an "unable to start program http://localhost:nnnn/Login.aspx" and "access is denied" error pop-up. If I closed the IE window, waited a few seconds, and then clicked F5 again, it usually started up my web app in debug mode just fine from that point on.
But today, that all changed. I did not change any configuration on my web app, which has been running fine, but I did add a couple of more classes to one of my subprojects. At this point, I could never get past the "unable to start program" message. I could run my app without debugging, but that was rather pointless. I even tried attaching to a running (non-debug) IE process, but that did not work.
Finally, I modified some of the properties in the WebAppName >Web >Servers screen. Specifically, I enabled "Specific port" for a specific HTTP port (which VS had been using all along), and I disabled "NTLM Authentication". I also enabled "ASP.NET" in the Debuggers section. Some of these I first clicked, then unclicked, then clicked again, saving in between each click.
This time, running with debug (F5) worked.
After running several times, I still usually get a "unable to start" error the first time after a recompile, but I can still usually get a debuggable running app to start after the second or third try. At least I'm back to where I was yesterday.
I suspect it has do with VS reloading its execution profile, and also probably something to do with permissions (since I cannot run as admin).
I'm using VS2012 with an ASP.net app that was written using VS2003... I've tried everything to get the IE page to open automatically when I select F5, or even Ctrl+F5... Haven't been able to get anything to work... However, I have stumbled upon a very poor work-around. When I select debug and I get the 'Unable to start program...' msgbox... I noticed that on the icon-tray I get a msg saying local-host has started
You'll notice a picture that the msgbox is pointing to:
Well, if you right click it, you get three options:
When you select the first: 'Open in Web Browser', it will open IE with the page your working with...
Like I said, it's a very poor work-around... but it works. This isn't an issue when I select debug using 'Chrome' or the page-inspector... But they have their own issues.
Try to turn on Bypass proxy for local addresses.
First you can go to your browser settings-> Change proxy Settings-> Connection-> Lan Setting and just check bypass proxy for local addresses.
If this solution don't work then also copy the following code check your web.config file for settings to bypass firewall:
<system.net>
<defaultProxy>
<proxy usesystemdefault="true" proxyaddress="http://proxy:port" bypassonlocal="false" />
</defaultProxy>
</system.net>
I easily resolved this problem by enabling script debugging in the browser.
When I ran into this problem (using IE 11) I noticed that iexplore was open about a hundred times in the task manager. After killing them all I was able to open my project just fine.
Since then, I have made a .bat file with this code:
taskkill /F /IM iexplore.exe /T
so now I just run the .bat when I get that error.
(alternatively you could run that code from the cmd)
I just ran into this problem in Visual Studio 2013. I had to enable Anonymous Authentication.
Click on the project node in solution explorer.
Hit F4 to show the properties window.
Change the Anonymous Authentication option to Enabled.
