After many tries to locate win vista installer(w/out SP-)
I installed a crack win 7 so could be up and running
any ideas on how to downgrade to original vista OS?

Any procedure I have missed with OEM distributions?
Also is there a win8 upgrade for win vista?
just want to know if there are other options to reinstalling Original OS?

Let's get you off that cracked o/s.

Why do you want vista without any service packs if I may ask?

There is an upgrade deal to win8 available from oct 26 th for $40 at online MS store- if you have vista/7 installed that will count.


Win8 is horrible on a desktop - but it's probably the cheapest way for you - unless you get the vista d/l from digital river which includes SP1.

Thanks for the response,

I have tried to use the SP1 vr. from MSDLC
error can not install w/ SP1 Installed(win7)?
but I had win8 installed preveiw vr.
DL win vista to try to return to that OS but failed-
Maybe time to wipe the drive and start over?
