Thanks for the suggestion but it didn't solve the problem unfortuantely.
I took a snapshot of the error box which pops up when i try to run SmartDraw 2009. The file which is falling down in WinXP is urlmon.dll.

I did a repair of the WinXP install but that didn't do anything. Btw, the old computer has the same version of WinXP. I used a Registry app to check for any errors with file links but it only found a few errors really from some orphaned registry entries of deleted apps.
I was going to buy the 2D version of SmartDraw 2009 because I only need to do floorplans.
Is there a trial of the 2D version available. Would that install any differently to the full package?
thanks
