So today was the first time ive opened cheat engine in months and it said that it couldn't find Cheat Engine 6.4.exe in its directory, but when i go to the file its in i can see it, and when i try running it, it just says it cant find the exe. I have no idea what caused it, ive reinstalled, restarted my pc, turned off anti-virus, and still cant open it.
That file is most likely a shortcut to the original .exe. Just reinstall. Anti-virus shouldn't flag it as harmful.
