Running with administrator privileges didn't help.
It still says something like, "An error occurred that caused the program to stop working. Windows will close this program, and if there is a known way to fix the problem, it will notify you."
- But it doesn't say what the problem is, where it is, or what the solution is.
And it doesn't say who or how it will be fixed.
I contacted technical support, and the answers were the same. First, I sent them system testing reports, and now I'm unsuccessfully trying to check the integrity of the files in the Uplay PC library. Presumably, this is in the Uplay client if you click on the game title under the avatar. I haven't found a small triangle on the "Play" button anywhere else. There should be a submenu somewhere that says "Check Files," but I can't find it.
Or maybe the Uplay PC library is located somewhere else?
This is quite a quest:smile52:
I'm going through all this just out of curiosity. I've already offered the game as a gift to several friends. Surprisingly, no one wants a buggy, licensed copy; they all prefer working pirated versions...

I received another email from technical support, but this time with instructions to fix the problem that are so convoluted that even the devil would get confused.
Just for fun, I did everything that was described. As expected, it didn't help.)))
It's clear that they decided to mess with me. Laughter aside, I still want to solve the problem just for the principle of it...
In the end, I decided to find a solution myself using the old, reliable method of trial and error.
I installed the Uplay launcher by downloading it from the website. I downloaded the game directly from the website.
I completely deleted the folder: C drive/Users/user/My Documents/ and deleted the Might & Magic Heroes Vl folder there.
I did think to copy the saved games from that folder.
If you're going to do something similar, copy the entire folder. The launched game will create a new folder, and you might be able to move some files from the copied old folder into it.
The game launched for me, but the problem is that all the progress in the "campaign" is gone. And there's no Russian localization. How can I solve the problem with the Russian voice acting now?
