PureBasic Forums - English

I'm using PureBasic 5.31, 32-bit, on a 64-bit PC running Windows 7 Ultimate. When I build an exe and send it to a friend running Windows 10, 64-bit, the exe throws up this error. Any suggestions on how to resolve this? Thank you.

may sound like a stupid question, you say that you are on 64-bit PC but is your OS 32 or 64 bit?

Is the exe installed on Win10? Notice that Win10 is complaining about a 64bit DLL when your 32bit app should be working with 32bit DLLs (nVidia "Capture Server Proxy").

Could it be that your friend has installed/saved the exe in Program Files? On a 64bit OS, that folder is for 64bit exe files only. Program Files x86 is for the 32bit exe files.

My OS is 64-bit. My friend installed the exe (via InnoSetup) and is running it from the equivalent of C:\App\Test.exe, not from Program Files.

Is this a trick question?

I'm thinking that all you need to do is use PureBasic 5.31, 64-bit to build your executable,
but probably this is a trick question and I fell for it. Right?

Not a trick question at all. Please note that the same exe on all OS before Windows 10 worked fine, so I think it's a Win 10 issue.

Anyway, if I build it with 64-bit PureBasic, won't that stop it running on 32-bit Windows?

A 64-Bit exe can't be run on a 32-Bit os.

Maybe it would help, when you post your source code or post the exact error message.

But he write a 32-Bit-EXE with a 64-Bit-DLL on a 64-Bit-OS.
This should be correct.

Could have told us that in the first post

So, yes it looks like a Win10 issue - possibly to do with security. Given that the app has an installer, it really should be installed where Microsoft wants it to be, in Program Files x86. I would modifiy the installer script to do that, see what happens.

Probably it has nothing to do with your program and it's a problem with Geforce Experience and Windows 10.
That error can happen executing any program.
Your friend should reinstall the nVidia crap or look for an updated version.
Also he should check if TMP and TEMP env. variables point to an actual folder.

Äh, when you have a 32-bit-exe, the dll must be also 32-bit....

Yes!
There is no way to mix !

Sorry, my mistake . You can run Exe be 64Bit-Os, but not run from
with 64-Bit-DLLs. These must be 32Bit-DLLs on 64Bit-OS.

A 64-Bit App can use a 64-Bit DLL and no other!
A 32-Bit App can use a 32-Bit DLL and no other!

It is very simple
