Problem with one vista 64 bit

[isnoend07]

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:

Umm...

Resolution:

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.
I read where it turned on by default on 64 bit systems, but you have to turn it on on 32 bit systems. this may turn out to be a bigger thing than i thought. I will have to turn it on xp,vista and win7 to test. i will have to read further, read
on place where the app may be trying to access memory that is not allowed. read another place of a work around but not written in vb

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