Hi Nigel,
It’s not even close to full.
I noticed at the Sony DVD Architect discussion forum that a couple of users had reported the same problem and they thought it had something to do with the Microsoft .NET 2.0 framework not being installed correctly. The thing is, I’m running DVD Architect Pro 5.2 on a Windows 7 Ultimate 64-bit O/S, so there is no .NET 2.0 redistributable to fix. Win 7 installs .NET 3.5 as the base framework, and you can’t install .NET 2.0 on Windows 7 (the installer aborts with a message that Win 7 already includes .NET 3.5).
I see that you are also running Windows 7/64… have you heard of .NET 2.0 not being installed correctly as a possible cause?
Thanks!
