Just a quick update with this thread...
You should be successful to package the 32bit version of SQL 2012 Management Studio on a Win7 32, using ThinApp 4.7.3, and running it on a Win 7 32.
I receive this exact same error when running the 32 bit package on a Win 7 64, though.
VSTCVENT :
- Did you try to use 4.7.3..?
- And the path is too long! During the capture process, instead of using the default location path for the capture, choose a folder very close to the root of the drive.
