What is the version of ThinApp used?
Is the application 32 or 64-bit? If 32-bit, suggest to package on 32-bit OS (Win7 32) rather 64-bit OS.
Thinapp 4.7.3 and captured on Win7 64 bit...we dont have 32 bit machines...client build is 64bit...Application is 32 bit
Are you able to launch the ThinApp on the Capture & Build machine?
I hope the deployment OS is Win7 64 bit. Can you try enabling WOW64=0 in the package.ini and rebuild the ThinApp?
