installer fails in Windows 10.

Trying to run openBVE-1.7.2.4-setup.exe on my Windows 10 machines. I get error message "This program does not support the version of Windows your computer is running". I have latest version of Net Framework, and have tried several Compatability setting combinations. Currently running openBVE 1.5.3.6 with no problems. What might I be missing?

Works perfectly on Windows 10 here, so I've got no initial idea.
The installer is a totally standard InnoSetup job, so I can't think why on earth it's failing.


Questions:
* Which Windows 10 edition?
* 32-bit or 64-bit?

Thanks very much for quick reply.

Windows 10.0.19041, 64-bit. Not totally standard in that I use Firefox in place of Edge and LibreOffice instead of MS Office. Doubt that is cause, but I'll restore the Windows defaults and see what happens.

If no joy, then will try to install using the .zip.

Definitely not, Firefox here & I can't see how that would affect it.

Stupid question- Have you tried with *no* compatability settings?
These should not be required under any circumstances.

IIRC InnoSetup should be smart enough to ask for admin when it requires it, but you might try running as admin.

Other than that, this is the only report I've seen of the installer failing.

I have tried it with no compatability, and as running as admin.
Have now installed from the .zip and it seems to be working on my very simple test route.
Thanks for your help, and thanks especially for keeping opentBVE moving forward.
