Pro Tools 7.3 on Vista

Is anyone familiar with running Pro Tools on vista??
I reciently got a replacement laptop from Dell with vista. My old machine had xp and now my software will not work.
It says i need XP to install it. I am entitled to a free download of the newer version (7.3 to 7.4) but because of the replacement machine the processor is not fast enough to cope with this version. Is there any way round this to get 7.3 working on vista (i've tried compatability mode which allows me to install it but i get error messages when i try to run the software)

 

What is it that you think Pro TOols will do for you?

 

I am a studying music tech and production and its what we use in the college so i need it for project work and such

 

I don't think there is a way around this, other than upgrading your machine. There has been quite a few apps I have found that fail in Vista, such as Cubase 3.5 Wavelab.

 

I had a feeling upgrading was my only option which is a bit on the difficult side being as i'm currently a poor broke student

I had been running cubase sx3 in vista with no trouble until i tried using the MBox as an audio interface and now i keep getting Unknown Error Messages.
I've been considering a downgrade to XP as another option

 

If your getting error messages while using your Mbox (although I have never used one) keep checking your sound card config. Had a real headache connecting a older box to a Vista machine that was eventually solved by playing with the Card options.

 

I had been trying the settings in the "sounds" menu in the control panel but still had no luck. Cud cubase be having trouble with the updated drivers for vista??

 

Yeah that sounds like the issue, are you using a pro soundcard?

 

no, just the onboard Sound card

 

Was reading some boards but cant find anything about compadibillity and your box, I can tell you that the answer is in the config of your onboard card and making cubase agree with it.
