Hey there, good evening. I tried running the trainer followed by the game (V1.1.5) Although the program seems to work in terms of authentication, it does not display the trainer itself. Tried to troubleshoot the .NET FRamework (is v4.5+) and any firewall issues (none pinged)
May I know other ways I can troubleshoot the problem?
Have you tried to whitelist the trainer (+Windows TEMP folder or only the files the trainer tries to write in the TEMP folder) in your security software (antivirus, etc.)?
Tried it with disabled AV and firewall? Uninstalled them?
Ran the trainer with admin rights?
It seems this Dungeon of the Endless trainer is blocked by Windows Defender even ran as administrator. I have excluded it as a file, the folder, the file extension, and even the process. And every time Windows Defender pops up with malware detected and closes the application. That's when you see the popup window of "Which application would you like to open this .tmp file with?" If I completely disable Windows Defender, the trainer runs fine until Defender turns itself back on later. After which, it closes the trainer and reports security issues and demands the computer be restarted.
This is the only trainer from Cheat Happens to have this problem, as I just checked a couple dozen others. My guess is that this trainer appears to be an older framework and the hooks it uses are blacklisted in Defender and those override any exclusion lists.
Ok, found a fix. Go into Windows Defender, History tab and check quarantined items / click View Details. There you will see the blocked file. Mine was a *.tmp file. Check the file and click Restore. Trainer runs fine again.

... or you can just create an exclusion for the tmp file called ~Mnn133.tmp which is also created/used by some older trainers.
It's located in the Windows tmp folder -> C:\Users\YourWindowsUserName\AppData\Local\Temp\
