I have an executable file which is .net 4.0 framework compatible.
When i am running it into windows 7 it is running normally, but when i tried to run it on windows vista then it is not running.
Please tell me is it possible to run 4.0 framework application on vista?
If yes then how, if not then why?
Most likely the executable fails to run because its dependency on .net 4 is not being met. Vista comes with .net 3 installed, but no later version. Which makes sense because Vista pre-dates .net 4 by many years.
Install the .net 4 runtime on the machine to resolve the problem.
well it was because of some dll files difference between windows 7 and windows vista.
i got them and solved.
Short version:
When I moved to Win7, I manually removed the MDAC 2.7 lines from my .ISM module, built it, and installed my software. It seems to work. Can I trust it?
Longer version:
We have just gone from XP to Windows 7. The software we deliver is C# (.NET 4 framework), targeting XP and Windows 7. It contains a few older COM modules, one of which is written in VB6. (Yes, I would love to rewrite this in a modern technology, but that's not an option at this point.)
I use InstallShield 2010 to build the installer for this package. Building this installer on XP worked with no problems. When I try on Windows 7, it wants MDAC 2.7 as a prerequisite merge module. Microsoft doesn't allow you to download 2.7 anymore, and I'm not going to get it from "Sharewarez R'us" sites.
The error InstallShield gave me when it couldn't find the merge module was: File not found. An error occured merging Module 'MDAC27ENU...'
From what I've read on the web, Windows 7 has the latest-greatest MDAC (now renamed WDAC) already installed. On a whim, I manually deleted the MDAC dependencies from the .ISM, built and installed, and my software seemed to run just fine.
What I think is happening is Win7 is noticing that something in VB6 is using MDAC and the OS is supplying the latest-greatest and it just works. I no longer need the merge module because Windows 7 has WDAC built in. (Can it really be that simple?)
My main question is: can I trust it?
My secondary question is: What about XP deployments? They will still need MDAC 2.7... Does that indicate I can't build on Windows 7 to target XP if I require MDAC 2.7? Please point me in the right direction. Thanks.
You need a comprehensive review (dependency analysis) of your installer. The VB6 runtime and MDAC/WDAC components are all built into windows these days. This is also the case with Windows XP and the latest service pack.
Either your ISM is referencing the MDAC merge module or it's referencing another merge module that has a dependency on the MDAC merge module. Hence why I suggest a complete review.
Without looking at your application I can't give you a 100% answer but odds are that if you implement a setup condition (launch condition) to check for XP latest service pack or newer that you will likely work without installing a bunch of stuff you don't need to be installing.
I am tryng to install a program on windows 7 but when i run tha installer i get a error message sayng: Please install .NET Framework Version 2.0 before installing the tool.
As i know the .NET 2.0 should be installed with w7 allready. So what might be the problem? Maybe there is a way passbye the checking in the installation.. or extract it or do something.
Just for more info i think its a installshield setup launcher. I tried to extract it but its not possible, getting the .net 2.0 missing error. So what i managed to do is to extract the msi from exe. And now when i run the -msi with /passive option from cmd the it indeed bypasses the .net check and everything gets installed. Now the problem is that im getting all kind of errors in the application so looks like its still not installed correctly.
My first guess is the program you install doesn't detect .NET 2.0 correctly. As you correctly mentioned, .NET 2.0 is pre-installed on Windows 7. See this article for complete picture.
While .NET is part of Windows 7, it's an optional component, though - you can turn it off.
Open the "Windows features" dialogue (by pressing start and typing/selecting "Turn Windows features on or off"), and make sure the "Microsoft .NET framework 3.5.1" is indeed installed.
If you're seeing errors in your app then maybe there's a problem with your .NET installation, or you have a client profile or partial install. What's the application you're installing - is it a server application?
I'm using Microsoft Visual Studio 2008 (VC9) to compile a project that has a .dsw file. I already have the 2010 and would prefer to use it, but it seems this dsw was built for 2008.
I'd like to compile and produce a binary that's also compatible with Windows 7. My questions:
if I compile with 2008, will the resulting binary be compatible with Windows 7? I'm not sure at which version of VS did Windows 7 support start.
or does this have nothing to do with the VS version, and is instead related to the Windows SDK? If that's the case, can I use VS2008 with a newer Windows SDK?
Can someone please clarify.
Microsoft has a great backwards compatibility "story", so pretty much anything you compile with any version of Visual Studio/Visual C++ will be compatible with Windows 7. The same may not neccessarily apply in reverse, i.e. if you use an API that's introduced in Windows 7, your application will error when you try to run it on prior versions of Windows.
There are a couple of things to consider though:
If the project was originally written to target Windows XP or earlier, it may fall foul of UAC
There are changes to directory structures (such as %systemdrive%\Documents and Settings becoming %systemdrive%\Users) that are fairly well handled by the link that Windows 7 creates in the root of `%systemdrive%, but you may fall foul of these.
VS2010 includes version 7.0 of the Windows SDK and VS2008 does not. You need Windows SDK v7.0 if you want your app to take advantage of Windows 7 features like jump lists.
Since you already have VS2010 installed, you can just change your include file / lib file paths in VS2008 to point to the Windows SDK v7.0 instead of the default one provided with VS2008. This is assuming you need that version of the SDK.
You do not need the latest Windows SDK if you do not plan to use the latest Windows 7 features like ribbons and jump lists. If you are building your app for the lowest-common-denominator OS (i.e. Windows XP), then really you should be fine using VS 2008 with default settings.
The other concern is, if your code was originally written before Windows Vista came out, it is likely that it will not work properly on Windows 7 unless it is run in Administrator mode, which is something you want to avoid. The only way to fix that is to rewrite much of your code to avoid writing to certain protected directories and avoid using certain APIs that require Administrator privileges.
Windows SDK is well backward compatible. See binary compatibility report between Windows 6.0 and Windows 7.0 on x86_64 generated by the abi-compliance-checker tool for the detailed comparison.

VS6 popped off a series of errors before bombing out completely during install on Windows 7. I specifically need to get VB6 functioning on Windows 7. Anyone having any luck?
Folks on the VB6 newsgroup report they have managed to get it working on Windows 7.
There's this step-by-step guide on how to install the IDE on Windows 7 (including 64 bit).
If that doesn't work (scrapes barrel) try this old tip about persuading the install not to install the Java VM? Link is now broken so here is the tip:
Before trying to install VB6. Create a new file, name it msjava.dll and place it in your windows directory. The file can be zero length. You can then happily install without the prompt to install an old version of Microsoft's flavour of Java. Once you have installed VB6, delete the msjava.dll otherwise windows update will prompt you to update it.
Or (scrapes hole in barrel) these tips from an article about getting the IDE working on Vista?
Footnote: if developing with ADO, be aware of this.
The only way I've found that works is Windows XP mode (i.e. a virtual machine). Works fine there, but otherwise, not at all.
I found ALL the answers in a thread at vbmonster.com. As mentioned above, you CAN install Visual Studio 6 with Service Pack 6 under Windows 7 by following Derek's detailed instructions at fortypoundhead.com.
I had a problem because I needed to install Service Pack 5. I use a third party program that does not work with Service Pack 6. A really smart programmer (GuideX) came up with a great hack to get around the MDAC 2.5 error.
Win 7 64 bit service pack 5 & 6. Turn compatability off and it seems to work.
Recently I had to debug an ancient application written in Visual C++ 6.0 on Windows 8.1. Tried different solutions all of them failed, only this one worked.
This guys made a special installer that allows installing VC++6, VB6, and SP6 on Windows Vista/7/8/8.1/10 without any errors whatsoever.
Hope it would be helpful to someone.
I installed VB6 on Windows 7 Pro without having to use compatibility settings or run as administrator.
Doesn't really help you, but does show that it can work.
Several people in my office have installed Visual Studio 6 (without VC++) on Windows 7, both 32-bit and 64-bit with no problems. The one thing we have in common: we've all turned UAC down to it's lowest setting. Nothing else special required.
I am using vb6 on windows 7 32 bit system for a long time.
you will need to install your vb6 with compatibility of xp2.
Create a 0-byte file in the C:\Windows directory called msjava.dll.
Don't just install via the Autorun executable; instead browse the Visual Studio 6 CD (or folder), right-click Setup.exe and select Run As Administrator.
On any Program Compatibility Assistant warnings, click Run Program.
Step through the setup screens until you're able to choose Custom Setup, then click next.
On the setup options, install the following items and nothing else:
Microsoft Visual Basic 6.0
ActiveX
Data Access
Graphics
Click continue and the process will start, and (hopefully) eventually complete.
Skip the installations of the MSDN CD, BackOffice, VSS and SNA Server, and clear the checkbox for "Register Now". Setup should be complete.
Download the VB6 Service Pack 6 from http://www.microsoft.com/downloads/en/confirmation.aspx?FamilyID=A8494EDB-2E89-4676-A16A-5C5477CB9713&displaylang=en and install.
Change the compatibility settings for Visual Basic (to get it to run a little more smoothly under Windows 7) by browsing to C:\Program Files\Microsoft Visual Studio\VB98, right-clicking the VB6.exe file, and selecting properties.
On the Compatibility tab, check the following:
Run this program in compatibility mode for Windows XP (Service Pack 3)
Disable Visual Themes
Disable Desktop Composition
Disable display scaling on high DPI settings
When you start up the IDE, you may get a notification saying that the color scheme has been changed to Windows 7 Basic, but it will be changed back to Aero once you exit. Everything should be working fine at this point!
Note: when you first run your new install vb6 run it with admin rights and with xp2 compatibility so that your exe can run on any system.
The word "supported" is used loosely in this thread, potentially leading the unwary reader to the conclusion that Microsoft supports the VB6 IDE (that is, the integrated development environment) on operating systems beyond Windows XP. This fact clearly is stated in the table that appears on the page at this link:
https://blogs.msdn.microsoft.com/nikosan/2012/04/20/support-statement-for-visual-basic-6-0-on-windows-8-updated/
Note that executables developed using VB6 are in fact compatible with Windows OS's from Windows XP through Windows 10--32/64-bit versions:
https://blogs.windows.com/buildingapps/2015/06/22/getting-ready-for-windows-10-sdks-compatibility-bridges/
Anyone using non-standard methods to coax the IDE into working on OS's that Microsoft does not support is exposing themselves/their organizations/their employers to risk and is not suitable for risk-averse organizations.
Having said that, I think the purest solution is to install Windows XP onto a virtual machine and run that VM in a modern host OS, such as Windows 10. That works just fine, and you can install directly from the VB6 Setup disc without making any pre-install/post-install customizations.
I had a Vista x64 box with a working copy of the VB6 IDE (which was supported). I upgraded the OS to Windows 7 x64 and the VB6 IDE still works fine. You could try that. I know, a huge PITA and kludgy but still, it worked for me.
I run Windows 7 Ultimate 32-bit, installed Windows Virtual PC - XP Mode, and that solved my problem isince I can run MSDEV 6.0 in the XP Window.
Not esay to install XP Mode though, the MS site is buggy.
The VB6 programming language is supported on the Windows 10 Technical Preview.
Visual Vasic 6 applications run and the VB6 IDE installs and works too.
I have the VB6 IDE running OK on Win-XP-16, Win-7-32, Win-7-64, Win-8.1-32, Win-8.1-64, win-10-32 and win-10-64 by using the instructions above which basically say, turn off UAC, run the installer AS ADMIN, and then set the VB6.exe file to run in XP-SP3 Compatibility mode.
I have had some issues with it and have had to do a bit more googling to solve these but I don't remember any more what those issues or solutions were.
I've even got the VB3 IDE running on the 32-bit versions of XP, Win-7, Win 8.1 and Win-10 - without even installing them - just copied the C:\VB folder from another computer and copied the *.LIC license files and *.VBX etc files as well.
I have successfully installed vb6 on win 7 32 bit by installing xp first then installing new win 7, (not upgrade), and do not format. then it will install vb6 without a problem
It's depending on your build version of Windows 7.
If your Win7's version is lower or is not updated, it has MANY PROBLEMS with compatibility.
But mine is newer Win7 version and has NO COMPATIBILITY TROUBLE.
I am currently using VB6 , VS6 and they still work fine!
If Properties->Compatibility->Windows XP doesn't help, fix it with UPDATING your Win7.
