The only problem I have about the whole solution is our assumption, which is currently valid, that the phrase MICROSOFT PROJECT is in the first 6000 characters and will always be followed by the version number. If MS changes this in the future then I would not know until my users complained that their input was being rejected. And I dont like to hear from user complaints. But that asided I will inform the money boys of my findings and how best to implement it. The pros and cons and then let them decide if it should be done.

This is a good way for you to justify always having access to the latest and greatest MS Project versions. MSP 2K2 is on the horizon.
