I had the IT guy in to take a look and he said it did not look like a permissions issue.
I'm trying to install AutoCAD MEP 2013 and Revit MEP onto a machine (where they were previously installed, but, had been uninstalled maybe 18 months ago... it's possible I only had 2011 and 2012 on here, not 2013, hard to say).
Windows XP SP3.
I did install AutoCAD MEP successfully from the same disc to my laptop (same OS).
Any tips on how to get around these errors (which completely stop the install)?
Screenshot001 is from Revit MEP, the 2nd one is from AutoCAD MEP.
After installing from the DVD failed, I copied the contents over to a local drive and tried that way. No joy.
