Windows 7 support

Commit: c710d2a
electron: 22.3.27
electron-builder: 25.0.5

I use nvpatch for my x64 build with Electron 22 which supports Windows 7. The resulting exe file can run on Windows 8 and more modern systems but doesn't start on Windows 7 64-bit. If I do not patch the exe file, it works on Windows 7.

Not sure why that would be off hand. Do you get an error messages (either directly on screen or in Windows event logs?)

[bulbigood]

Unfortunately, exe just won't start without any errors. I didn't find anything in the logs. There is nothing in Windows Events regarding my exe file.

[toptensoftware]

Perhaps try running dumpbin /headers on Windows 7 on the original and patched exe and see if it shows up anything odd?

Unfortunately, I don't have much time right now to dig deeper but I'll take a look when I get a chance.

[bulbigood]

I installed MSVC Build Tools 2019 to get dumpbin. It's the latest version available on Windows 7.
There are results:

Non-patched (working) exe
