Troubleshooting
If a trainer doesn't activate: verify the installed game version matches this page's listed build, install the latest Visual C++ Redistributables, and check that your antivirus hasn't quarantined the executable. After a game patch, check this page for an updated trainer build.

Antivirus, ban risk, and online compatibility:
Antivirus false positives: KELDER Trainer contains memory-editing routines that trigger heuristic antivirus warnings — this is a known false positive across the entire trainer/repack category, not actual malware. Each post page links to a VirusTotal scan documenting the false-positive engines.
Online play and bans: KELDER Trainer is for single-player and offline modes only. Online multiplayer modes protected by anti-cheat systems (EasyAntiCheat, BattlEye, VAC, FairFight) detect memory editing — using a trainer online can result in a permanent account ban. Never deploy in competitive online play.
Compatibility note: KELDER Trainer targets the build version listed at the top of this page. After a game patch, an older trainer build typically fails silently — recheck this page for an updated release.
