When installing AMUMSS...

  • there can be no accented characters in the installation path
  • always install to a path outside of Windows UAC control and never within a system folder
    Good example paths: C:\AMUMSS, C:\Modding\Tools\AMUMSS, F:\AMUMSS
    Note that the Desktop is also a system folder.

When installing to the previous installation folder, AMUMSS will preserve everything in the user folders except changes made to AMUMSS files in the following folders:

  • ModScriptCollection

When installing to a new folder, users can copy/paste the following folders from their previous installation of AMUMSS to preserve previous work:

  • 'ModScript'
  • 'ModExtraFilesToInclude'
  • 'Builds'
  • 'SavedSections'
  • any other files in AMUMSS main not updated by the unzip file

Please execute BUILDMOD.bat once to re-create all user folders (if they do not exist) and download\update MBINCompiler.exe and libMBIN.dll.



Sometimes, your anti-virus may detect some component of AMUMSS and block/quarantine it. Be assure the download wasn't infected, but AMUMSS's behavior may be interpreted as such by some anti-virus software.

  • Please make sure to create an exception in your anti-virus software when this happens.
  • Also a reboot may be required as some anti-virus software do not correctly register the exception when it is created.
