I get the error when the wizard comes up saying "Preparing Setup" before I can click on anything.
Here's the full error:
Error Code: -5004 : 0x80070005
PAPP:ConceptDraw VI Standard
PVENDOR:Computer Systems Odessa corp. (www.conceptdraw.com
@Windows XP Service Pack 2 (2600) IE 7.0.6000.16441
I clicked on "Report" and it took me to a Installshield web page to submit the bug.
It's too bad, because I really was looking for this sort of tool!
