You can use the LargeAddressAwareparameter to capture applications which install on both 32-bit and 64-bit operating systems.

ThinApp can capture applications which install both 32 bit and 64 bit application and components together. It is possible that 32 version of application launches 64 bit version. In rare cases with ThinApp, the 64 bit application might fail to start from 32 bit application. To solve this problem set a package.ini parameter LargeAddressAware to 1 in the package.ini file and rebuild the package.
