My installer require admin to run setup to register ocx's dll's and includes a manifest to run as invoker. This works well on many systems with no problems, but on one machine running vista 64 bit the app will not start and windows displays a message "Windows has closed the app to protect the system" and the program closes. What could be the problem ? Corrupted downloaded setup?
Or ?
Sounds a bit like a DEP fault:

To avoid this behavior, contact your program vendor to see if an update is available that enables the program to work correctly with DEP.
This DEP is something i never knew existed.Quote:

DEP is a way to prevent program bugs or malware from trying to execute data as code.
