Project 2003 and 2007 running concurrently on same machine

**Lindberg** · 15-01-2009

I want to know if i can run Project 2003 and Project 2007 on the same machine. Actually i have some 2003 projects but i am looking forward to start a new project with 2007 on the same machine. So is that possible??

No worries mate you can install Project 2003 and Project 2007 on the same machine but just make sure that you are backing your data after certain period of time. There are some people who have already tried that out and have complained that Project 2007 has stopped working suddenly in their case because of some virus or in conflict with some other application and they had to reinstall both the versions again. So in that case, if you will have the latest backup then you can overcome such problems if they occur in your system anytime.

I want to install project 2003 on my laptop (vista SP 2 updated, 32 bit, 2.00 Hz, 3 GB ram) currently project 2007 pro is being installed. The project 2003 is required to convert my project files to primavera 6.0.
So how to go ahead, are there are any installation things that need to be taken care as I dont want my 2007 to stop working.

You can install Project 2003 and Project 2007 on same PC if you want to. But you will need to install 2003 first and then 2007. Microsoft deliberately designed for this to make upgrading easier. I have both running on my desktop and laptop as different customers have different versions. So, it is fine to have both the ms project version installed on same pc.
