How to update from CREO 4.0 to CREO 5.0 .

[STEVEG]

We need a lot more information than just that.

Just a few off the top of my head are:

Do you have an account on PTC's site and is your maintenance up to date?

If it is, did you download the new version?

Are you a student or working for a company?

Are you the Creo admin?

Do you have admin rights or doe you even need it?

Etc...

... or contact your VAR (Value Added Re-seller). A lot of times they can walk you through it.
