Can't launch installation

i wanted to install client on my w7 system, but i am getting error message that some GetFileVersionInfoExW couldn’t be found in library VERSION.dll. I am aware that problem is most likely on my machine, since I had client installed last time around begining of 2022 and it was fine. If someone could advice me how to fix it without formatting whole system, I would be really happy. Thanks everyone
