AFAIK, Windows Server 2019 is based on Windows 10 1809 (see HKLM\Software\Microsoft\Windows NT\CurrentVersion\ReleaseID) so the GUID is the same, ie {8e0f7a12-bfb3-4fe8-b9a5-48fd50a15a9a}.
Glad you found a way out, but here are some other funny solutions:
Most devs actually just grey out the button (disable=True) but actually the code that would be called will not check whether the button was disabled or not.
There are some tools specifically designed to "re-enable" MFC gui buttons.
One that worked for me was TurnItOn! Enable link to author's site
With that, just enable that button and enjoy.
If this is not working, other tools like this exist that might support various MFC / GDI controls.
Another batch of solutions:
- Windows compatibility mode (probably won't work)
- Use SandboxIE sandbox to install your software, tricking it into thinking it's being run on Windows earlier versions. If you need to adjust the sandbox's returned registry keys, you can find what registry keys your installer is reading with Microsoft Procmon
Just don't forget to make a process filter on your installer executable so it reduces your search scope. Once you found the key, open regedit.exe from your sandbox and modifiy the appropriate GUID. (Disclaimer: might not work if the GUID is given by some internal Microsoft API... If so, C skills will be required to get output of that API).
- Use Virtualbox with a previous Windows version (not elegant solution)
- Guess what installer your software was packaged with and open it in 7zip or whatever does the job (works on NSIS, does not work on InstallShield)
There's also a quite ultimate solution for this that needs a bit of work but usually works great: Create an alternate installer for your software:
- Check what registry settings and files are created when installing your software on an earlier Windows version. Use RegShot to track registry modifications (filter out always changing keys like catroot etc). Again, you can use SandBoxie to easily track file modifications.
Once you got that info, just create a SFX file containing your files and the .reg file, which you can import using reg import file.reg (can be launched directly from the SFX maker, ie 7zip or something alike)
Also check if your software came bundled with some runtimes (Visual C or so) and add them to your installer.
Hope this can help.
