We've recently installed a Project Server for one of our customers. One of the pc's gives the folowing error message when opening PWA:
Invalid Browser Version
Internet Explorer version 5.0 or later is needed to use Microsoft Project Web Access.
This is when we open IE7 and go to the PWA webpage. The Project Server version is 2003 running on SQL 2005. User accounts are synchronized with AD.
Other PC's have not given this problem in the domain.
