Hi, Thanks to all who post to this forum. Lots of good tidbits in here! I am hoping to find a way to install firefox2.x silently to a specific directory... Extracting the latest firefox2.0.0.12.exe, I got directories and another setup.exe. Extracting that got me an [NSIS].nsi file, which made me believe that I could use standard NSIS commands (setup.exe /S /D=%PROGRAMFILES%\Internet\Firefox2) but was not successful. The NSIS script seemed to be assembly, which confused me, but I'm not big on NSIS scripting anyway. There does seem to be a place where "$INSTDIR" or something similar located, but didn't see any clear way to modify it's value. Anyone know a good (and relatively painless) solution for me? Thanks!
