It went through the entire installation procedure. But when clicked on to open it made only the initial VW screen frame and then immediately projected the windows error message. VW did not launch. Are you supposed to install the 2008 upgrade program with the VW 12 on the PC. Though I ordered the 2009 upgrade, the box does not say upgrade, it appears to be a typical full version. With or without version 12 on the PC, the same error message appears. Is there a README document on the installation DVD?

"Vectorworks 2009 Application has encountered a problem and needs to close. We are sorry for the inconvenience." It came up just after the initialization started. Exception Information: Code: 0xc0000005 Flags:0x00000000

I have twin opteron 244 (@1.8gig), 4 gig of RAM, Matrox Parhelia 128 graphics card, 75 gig WD Raptor hard drive. Upgrading from VW 12 to 2009. Upgraded w/ v.12.5 still on the hard drive first. MS error message came up, therefore, thought maybe 12.5 had to be removed first. Did that. Still get error message at VW startup. Tried copying from DVD to hard drive. Failed again. The program puts QT on automatically, so no conflict there. Just sent a message to tech support, but don't want to wait till Mon. Weather is keeping me in so I need to keep busy.

I ran the 12.5.2 update and it works fine. There are two zip files in the list that start with the number 1200. Do they contain essential components that must be unzipped, and what are they?
