I did a capture of a VB.net 3.5 application on a clean XP system using ThinApp 4.5. It can be only loaded on XP. On Vista or Win 7, the main form would not load because one of the ocxes failed during the InitializeComponent's EndInit method.
I tried the capture again on Vista. Now it works on Vista only. Captured on Win7 and it works on Win7 only.
Then I did a capture again on XP using ThinApp 4.3, and used 4.5 to build it. It loads fine on XP, Vista and Windows 7.
It seems there might be bugs with the capturing process of ThinApp 4.5.
I tried to use Log Monitor to generate a log, but it crashed at the very beginning...
