Why do I get an error message Unable to Connect to Pro/Engineer?

There are two reasons you may see the error message shown to the right:

• You have not yet configured the Pro/E environment variable. For a description of how to do this, see How do I use the direct import from PRO-E?.
• You may be hitting a Pro-E bug which causes CAD links to "time-out" on January 10, 2004. You can download a patch to fix this bug from http://www.ptc.com/go/timeout/
