What to try when you get a "won't run" program error:Turn DEP off!

[surfer100]

For the last several months I've been getting "won't run" error windows for
HP's My Display software, for Vueprint graphics program, and for another
program. I
I was getting the same error message for each... A window would pop up and
say "program X won't run" but DID NOT SAY that it was a conflict with
Vista's Data Execution Program. I found out ultimately by lots of repeated
googling.

I turned Data Execution Prevention to OFF, execept for essential windows
services by going to control panel, click on system, click on system
protection, click advanced tab, click settings, click data execution
prevention tab, and finally click on "turn on DEP for essential Windows
programs..."

You can also turn on DEP except for for programs that you add to an
exceptions list , but I found this DID NOT work for some progams I wanted to
run, so I've left DEP on ONLY for windows services.

I suspect that some one of the many vista security updates changed the DEP
settings, or updated the DEP program and changed its default settings. But
the error messages then generated don't tell you what the problem is!
Anyway, I've turned it off and everything is back working again.
