® Thinstall packaged applications can run on Virtual PC ® Version 6.1
Some versions of Virtual PC on the Macintosh need an option enabled before running Thinstall packaged applications:
VirtualPC for the Macintosh pre-translates blocks of i386 code to PowerPC code to achieve higher performance. Because of problems with Virtual PC's page caching mecanisms it may fail to run self-modifiying program. All Thinstall packages are self-modifying to achieve better code security.
To use a Thininstall-protected program on VPC/Mac, you need to disable this pre-translation. This is can be done on VirtualPC 6.1 and later versions.
User with Virtual PC 6.0 can upgrade to Virtual PC 6.1 using this page:
