Hi Rikki
Make sure you have the latest version http://www.asio4all.com/ as it is now compatible with Win 7.

If you have an old program that won’t run in Win 7, load and run it using Windows compatibility mode, (Your given various OS options when you select it) which unlike compatibility mode in XP, actually works quite well.

In addition the sound drivers have been improved in Win 7, so you may find you will be able to set them to a low enough latency, without using other drivers.

Hope this helps

Bill
