Get someone to log into your machine and run the install for you? Get team share.
Honestly I’ve installed dozens of copies on dozens of machines. Including the latest.
There are about half a dozen post where the latest does not install. But this is not a trending problem. All of these posts were made by you.
So you need to accept the fact that your computer is the 1 thing here that is not working. And it could be anyones guess as to why.
After uninstalling Direct X. Did you reinstall Direct X?
Cheat software, such as Mods that you download and install often work by removing the Direct X DLL’s and replacing them with their own. You will not be able to properly run the installer when it sees that the DLL’s in question are not the proper ones. So yes. You must remove all cheat software…
Uninstalling Direct X should fix that. Reinstalling should make sure you have the proper DLL’s. Repairing the installation might.
Can you share the link where you downloaded the installer?
