I looked for but was not found a solution, the installation, again, of the update did not work.

Thanks !

  • Stop all AMP instances
    • Run AMPs installer in repair mode
    • Run 'ampinstmgr --nocache upgradeall'
    • Reboot

Hello, when i run Amp installer in repair mode, i get this error :

The file 'steamcmdplugin.dll' cannot be installed because the file cannot be found in cabinet file 'cab1.cab'. This could indicate a network error, an error reading from the CD-ROM, or a problem with this package.

And when i run 'ampinstmgr --nocache upgradeall', the launcher crash instantly.

Download a fresh copy of the installer. Do an uninstall/reinstall if necessary (this won't affect your existing AMP instances, it's just the instance manager)

No change... Same Error... And 'ampinstmgr --nocache upgradeall' is not recognized as a possible command
