I have been working on an MFC project recently. I generated it's installer using Deployment Project from Visual Studio 2010. The problem that I am facing is that when I install my software on a windows 7 system, the adobe reader on that system stops working and throws away an error dialog with following message "Acrobat failed to load core dll". As soon as I uninstall my software, adobe reader starts working again. This problem doesn't occur on every system. Could you point out what could cause such a problem?

In new Visual Studio for Mac - how can I create a Windows Forms Application - or the most similar thing to one? And in the latter case - can I open an old Windows Forms Application-project in this? This is for a student school task, where we are to open an old Windows Forms Project created as an example - run it and get inspired to create a new one. Is it possible to do so from the new Visual Studio for Mac?
It is possible to open and run in Visual Studio for Mac a Windows Forms project created in Visual Studio on Windows. It may work in some simple cases, but generally it is not supported, and when it crashes, nobody will help you. I tried to migrate my WinForms project and stopped after getting a crash when trying to show a NotifyIcon:
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
Unfortunately, it is a dead end.
Using Visual Studio 2013 Ultimate update 4, I have developed a universal app for the store and the phone under Windows 8.1. The app is implemented upon the Prism for Windows Runtime.
The app is at its final testing stage. I have no problem to run/test it with the corresponding emulators and devices (Surface Pro and Lumia 1020) until few days ago. Although the app can still run/test with the emulators (The store app can be still packaged and deployed to Surface Pro for testing). But I will receive following error message when running with device (Lumia 1020) under Visual Studio 2013:
Unable to activate Windows Store app …. The xxx.exe process started, but the activation request failed with error ‘The app didn’t start’.
I have tried all followings in number of times, still received the same error message (there is no app.config file used in app (at least not being seen in the solution pane and windows explorer):
Roll back to the change set where I have successful made the build and deployed to Phone.
Run repair on Visual Studio
The problem has been fixed.
I have used MS Ocr Lib. for Phone once which only works for ARM. After using NuGet to remove Ocr lib., OcrResource folder still remains in the phone project.
To fix the problem, one must either deletes OcrResource folder if the target platform is for Any CPU, or keep OcrResource folder and set the target platform as ARM.
I'm having trouble installing Visual Studio 2012. When I run the installer I get the message:
Microsoft .NET Framework required for Microsoft Visual Studio Professional 2012 setup
The first time I got this message, I clicked to install. It loaded some stuff but it didn't look like it installed anything. I ran the installer for VS 2012 again and I get the same message but now without any buttons to click on. Is there any solution to this?
What happened before
I had VS 2012 already up and working. I left it alone for quite a while until I decided I wanted to do some programming again. Starting the application resulted suddenly in an error:
Cannot find one or more components. Please reinstall the application.
After searching for a couple of hours I couldn't resolve the problem so I did as it asked and reinstalled VS, but I got the same error again. Then I tried to remove every single application VS installs as indicated by this list and any program that had a similar name. I also removed all .NET versions and C++ redistributables. Now I can't install VS anymore and some games and gadgets are now broken.
And I always, always, always forget the existence of system restore. I doubt my oldest system restore is old enough. This is going to be my last resort.
What I tried
Search for a .NET installation in the control panel, it's not present after clicking the install button on the prompt of the VS 2012 installer.
Reinstall .NET 4.5 using this installer. It installs correctly, but the problem persists.
Turning .NET 3.5.1 off from windows features and install it manually. This fails for an unknown reason (error code -2145124329, which seems undefined). Just turning it off doesn't work either.
I recently installed Visual Studio 2010 to help me with some exercises for class.
It all worked great in school but when I got home and tried to run and debug the second program I got this error:
Unable to start ...\Kapitel_1\Debug\Kapitel_1.exe
This application has failed to start because the application configuration is incorrect. Review the manifest file for possible errors. Reinstalling the application may fix this problem. For more details, please see the application event log.
How can this be solved?
This message generally means that the machine on which you built the application did not have the same redistributables than the system where you run the application.
Redistributables are sets of DLLs needed for your application to run properly.
In your case, I noticed that you are trying to run a debug build. That might just be the problem: you cannot run an application or use a DLL that has been built in debug configuration on a system with no debugger installed. Installing Visual Studio (ideally the same version your school has) should do the trick. You could also rebuild your application in Release configuration to avoid having to install a debugger on the running system.
Another case where this error message might be displayed is if you just installed a new Visual Studio update on the system that built the application and not on the system where you are trying to run it. In that case, you would need to update your system with the latest set of redistributables from Microsoft (at time of writing, here was a good place to look for that).
I recently had to reinstall the OS on my dev box and I am now in the process of reinstalling various applications. I had previously installed the WP7 SDK without any problems but unfortunately I'm having problems this time around. The only project type I have available in the Silverlight for Windows Phone category is one that I downloaded from the online templates section.
When I try to open it or any of the WP7 projects I created previously I get a "The project type is not supported by this installation." error. I am not sure what I am missing. I have followed the three steps listed here so I've installed the SDK, the Dev Tools and the Dev Tools fix. The installation of VS2010 itself seems to be fine as I can create ASP.NET and Silverlight applications and run them without any problems.
Has anyone encountered something like this before?
Edit: I have installed Service Pack 1 for VS 2010 but that hasn't helped unfortunately.
Edit: I have also re-installed the Windows Phone Dev Tools and that installation reported no errors but I still get no projects under the Silverlight for Windows Phone category.
Try opening a visual studio command prompt and typing:
devenv /ResetSkipPkgs
I have thankfully resolved this. Last night I uninstalled everything and reinstalled again but this time I made sure to right-click on each executable and select "Run as administrator". That seems to have done the trick as my existing WP7 projects are compiling and running successfully and I can create new ones too. I did run into two error messages however -
"Zune software is not launched. Retry after making sure that Zune software is launched". I got around this initially by setting the target to Windows Phone 7 Emulator instead of Windows Phone 7 Device in the target dropdown on the main toolbar.
"Error: Connection failed because of invalid command-line arguments." I got around this by rebooting as mentioned here.
