Install Fujitsu-Siemens version
If you want to install a Microsoft Office and you happen to only have an OEM version from Fujitsu-Siemens, you'll
notice that it refuses to install on any Non-FSC-PC. But after some peeking around on the CD, you'll find a
suspiciously large file Install\OFF_FSC.EXE with around 250 MiB.
Taking a look at it reveals something strange:

This doesn't look like a normal EXE file, it's missing the typical MZ header. Also the following data looks
encrypted, i.e. somewhat random.
Somewhat below you'll find some strings which have to do with unpacking - so the file seems to be a crypted self-extracting archive.
Going several pages further down, you'll find something familiar:

MSCF stands for MicroSoft Cabinet File. It's a header for the standard CAB archives used to distribute software.
The AUTORUN.INF, CC561401.CAB, etc. are also a clear sign that this seems to be the index of the archive. The
letters MSCF are mentioned several times before this location but there was no file index near them. This one here is
clearly a standard CAB file.
So now take your favorite Hex-Editor and cut everything up to the MSCF header. The new file has to begin with MSCF.
Rename it to something .cab and use your favorite archiving tool to unpack it. Et voilà!
