The Verdict: The Fatal Error RMN60 is one of the most infamous launch errors for Grand Theft Auto IV on PC. It is not caused by a single issue but is generally a symptom of the game’s notoriously poor PC port conflicting with modern hardware and software. Specifically, RMN60 is almost exclusively tied to Windows Media Player (WMP) dependencies and security software interference . Pixel Speedrun 6x Exclusive Online
GTA IV relies heavily on Windows Media Player codecs to run. On modern Windows (10 and 11), WMP is often disabled, uninstalled, or "bloatware-cleaned" away, causing the game to crash instantly with RMN60. Metal Gear Solid 5 Phantom Pain Crack Fix Patched - 3.79.94.248
Many modern antivirus programs (including Windows Defender) flag older SecuROM DRM files—used by GTA IV—as malware (specifically Trojans or HackTools). If the antivirus quarantines these files, the game launches, realizes the security check is missing, and throws RMN60.
Games for Windows Live (GFWL) is a dead service that creates conflicts on modern PCs. While RMN60 is usually a media error, GFWL can cause cascading failures. Replacing the GFWL file with a "dummy" file is standard practice for getting GTA IV to run today.
Unlike other GTA IV errors (like RMN40 or D3D errors), RMN60 is easier to resolve because the root cause is usually binary: either the game cannot find the media files it needs, or your antivirus is deleting them.

Because GTA IV was built for Windows Vista/XP/7, it often struggles with permissions on modern Windows. While usually a fix for other errors, it can resolve RMN60 if the game cannot access system files.
