MFC SDI Error on save on windows 8 - windows

I have developed an MFC SDI app, which uses the default CDocument Save, Save As and Load Menu Options. When I run this app on Windows XP, Vista, or 7 the app works fine - it can save and load documents without issue. When I run the same app on Windows 8 or 8.1 and click the Save option, the app crashes with a generic error message. Is there something extra that I need to install for it to work on Windows 8? Or is there something special I need to do to get an MFC SDI app to work on Windows 8?
I have tried to install Visual Studio on the Windows 8 machine to compile it there but I only have the Express version, which doesn't come with the MFC libraries, so it will not compile. The PC I wrote the app on, was a Windows 7 pc.
I am not too sure what other information might be useful.
EDIT:
The error message

I have managed to compile MFC applications in older versions of Visual Studio Express, see:
http://www.codeproject.com/Articles/30439/How-to-compile-MFC-code-in-Visual-C-Express
To get this to work in a recent VS Express will probably require some tinkering.

Namespace issues in VS2017 and Win7 with Xamarin app?

I have VS2017 Community edition installed in a Windows 7 PC and a Windows 10 laptop. They both have the exact same installation.
Last night I created a Cross-Platform > Mobile App (Xamarin.Forms) project in my Win10 laptop, and it ran perfectly in the android emulator. No issues there.
I did the same exact thing in my Windows 7 PC, and I'm getting tons of compiler errors. All of them are of the The type or namespace name 'System' could not be found nature.
Is there anything I need to do in Windows 7 so these projects run?
In both environments (Win7 and Win10) I did the exact same thing: installed VS2017, created the new Xamarin cross-platform project, and debugged it. In Win10 it runs flawlessly while in Windows 7 I get a bunch of compiler errors with System namespace, which is literally the most fundamental namespace of the .NET Framework.
Any help is appreciated.
I'd like to add that I created a regular ASP.NET Web Application in Windows 7 and it runs flawlessly (no issues with System namespace), so it's an error with Xamarin cross-platform.
The solution for compiling the solution successfully on my Windows 7 PC was to install .NET Framework 4.7.2

What is required to run a VB Group Project on Windows XP and Windows 7?

I had an application written in VB on my laptop which was running Windows XP until I formatted it yesterday. A friend copied it over several years ago but it's not possible to contact him anymore. This project consists of .vbg, .vbp, .vbw, etc. files and a few .mdb files which store the databases. I also had a shortcut on my desktop which was referencing a .vbg file which used to open up a window and I was then supposed to press a "Play" button to launch the application.
I've copied the required folders over to my new laptop which now has Windows 7 Professional (32 bit) but I have no idea how to run this application and what is required. I also tried creating a VM using Windows XP just to check if the problem is with Windows 7 (or above) but still I am probably missing other required software (a debugger perhaps? visual studio or something?).
My questions are:
Is it possible to run this project on Windows 7 and what software is required to accomplish that?
What am I missing on the Windows XP VM? Do I have to install Visual Basic or some other debugging software?
Appreciate your help,
Kyriacos.
First of all, you need to have visual basics to run the .vbg or .vbp files. There is no other application that supports those formats. And Second, you can run the project on windows 7 as it is compatible all the way to windows 10.

Create windows app package for 8.1 from windows 10

I have a bunch of devices we sideloaded our app onto that are running windows 8.1
I was having problems with our project after I upgraded my dev machine to windows 10 so I created a new project using the standard blank project template. I then reimported my html/js code and started fresh.
This took care of the issues I was having but apparently the new template is only for window 10 and greater.
When I try to sideload onto a windows 8.1 machine it throws an error saying element:m does not meet the spec inside my appx package manifest.
I looked at both spec's but nothing is jumping out as being wrong, although there are differences.
I can't seem to find in the windows doc's what to do. Has anyone tried this?
What I want to do is create an app package for windows 8.1 machines from my windows 10 machine using Visual Studio 2015
Edited for clarity.

WTL on Windows 10

Has anyone used WTL on Windows 10 already? All applications that I create with WTL segfault on Windows 10. They work on Windows 8 and Windows 7.
I even tried the most basic Hello-World application in WTL on Windows 10 and it segfaults when I run it. There are no clear indications of what is wrong. The program just segfaults with generic Windows segfault error.
Looks like WTL isn't Windows 10 compatible yet? Has anyone had this problem yet.
Just asking here as others will probably have the same problem. I tried two different Windows 10 (pre-release beta, and official release). I'm using latest WTL version WTL 9.0.4140 Final (2014-05-30).
All of our commercial applications are WTL built in VS2008. They work fine on Windows 10. If you can get a dmp file you should be able to review the crash dmp in windbg and see what is causing the fault.
Windows 10 with Visual Studio 2015 Community compiles and runs WTL sample MemDlg, I used WTL91_5270_Beta
our commercial video application is WTL-based(vs2015 express).
work fine, but it act different to MFC-based applications.
when win10 menu popup, video frame-rate drop in MFC(26fps->10fps), WTL(26fps->5fps).

Has anyone had success with Visual Studio 6 on Windows 7?

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.
