QT5Core.dll error
-
One application stopped working after I reinstalled original Win7 to some custom version Win7. Now I'm getting error saying that there is no entry point to procedure _Z11qUncompressPKhi in QT5Core.dll. Tried different DLL versions, downloaded QT package, copied DLLs from there of the same version, but sizes somehow different. Any ideas what could be wrong? Thanks!

This format of name mangling tells me that your app is is built with MinGW/GCC. Therefore, you cannot use Qt DLLs that are built with MSVC.
The best way to fix the problem to re-install your app using its official installer, to get the correct copy of Qt DLLs. If you don't have an installer, find out exactly which version of Qt your app needs.
Also, remove Qt from your system PATH (if it's there)
FYI, see https://en.wikipedia.org/wiki/Name_mangling#How_different_compilers_mangle_the_same_functions

Thanks, but tried reinstalling multiple times. Can't see anything QT related in PATH and other variables. Also removing QT5core.dll from app folder doesn't make app load it from elsewhere. I wonder if problem might be in cyrillic Windows version I switched to?

That's very interesting. Is this app publicly available? May we know what it is?

I suppose we can't rule out that possibility, but I can't think of a reason why the language would affect your DLL loading.

https://www.uosteam.com/I installed UOSteam in a VM and I can see that it uses Qt 5.1.0 with MSVC 2010. UOSteam is probably not the one that's looking for

I did not install this because it's a big file and I have a slow connection.

OK, it looks like UOSteam runs properly for you.
I'm guessing that your error is coming from the game client itself. Have you tried reinstalling that? Does it use Qt?
