vb.net upgrade : VB upgrade crashes with Data Execution Prevention

I had a peculiar problem yesterday which I thought I'd post here in case
anyone else runs into it. I'd successfully run the VB upgrade wizard a while
ago on quite a complex VB6 project, and I was trying to run it on another
one. But whatever I ran it on, it reported a crash in vbu.exe, "The exception
unknown software exception (0xc00000fd) occurred in the application at
location 0x7c9379cd". In fact 0xc00000fd is stack overflow. It turned out
that this problem was caused by having Data Execution Prevention switched on
- my machine has hardware DEP support - and if I turned it off the upgrade
wizard ran OK. So it looks like there are some DEP issues in the upgrade
wizard.

Hi Phil,

You're correct the version of the Upgrade tool that shipped with VS 2002,
and 2003 can not run with the DEP switch turned on. I believe this KB
article descripes the issue further:
