Installing Acrobat 7.0 requires that you first install IE6. For me, installing IE6 had to be done as unsupported software, using a seperately downloaded ie6setup.exe from MS. I tried to install acrobat 7 in the same bottle, but it failed on the error "...INSTMSIA.EXE not found". The installation package I had (copied from network share to local directory, and working under windows) doesn't include an instmsia.exe, although it does include an instmsiw.exe. So I couldn't get it to install at all.
