I know this is old, but this is the only post that came close to what i'm trying to do. Instead of creating a separate addon, can I just add "[registry_addreg]" to an existing entries.ini file? For example: [general] builddate=03/02/2009 description=7-Zip language=English version=4.65 website=http://www.7-zip.org/ [EditFile] I386\SVCPACK.INF,SetupHotfixesToRun,AddProgram [AddProgram] 7z465.exe /S [registry_addreg] HKCR,".7z",,0x0,"7-Zip.7z" HKCR,"7-Zip.7z",,0x0,"7z Archive" HKCR,"7-Zip.7z\DefaultIcon",,0x0,"C:\Program Files\7-Zip\Formats\7z.dll" HKCR,"7-Zip.7z\shell",,0x0 HKCR,"7-Zip.7z\shell\open",,0x0 HKCR,"7-Zip.7z\shell\open\command",,0x0,"""C:\Program Files\7-Zip\7zFMn.exe"" ""%%1""" Will this work?
