Sony Vegas 7 with Windows Vista = Problems

[ForeverZeroo]

This pairing gave me problems on my last computer (with vista) but someone told me how to fix it.
flash forward a year later and my computer was stolen. and i forget how to fix the problem.

i took notes while installing and opening windows vegas 7.0

here they are:

program has known compatibility issues:
program: Microsoft SQL Server MSDE
Publisher: microsoft
Location: N/A

clicked "check for solutions online" button and it found nothing

--------

the media library database maintence failed.
unable to locate osql.exe tool

but says "Sony Media Manager has been successfully installed

-----

I open it and "Windows host process (Rundll32) has stopped working" pops up

---

Vegas will then open and look normal.BUT it wont let me enter my serial number.


PLEASE help. i need to get working. :<

That shouldn't make a difference either way...

Try disabling DEP (Data Execution Prevention) for Vegas 7.
