I've been using Wavelab 6.11 on my computer running windows 7 with an i7 processor. I've recently put my copy of Sonar 8.5 64 bit on this computer. Wavelab did not show up in the tools section.(which I knew would happen) I found the instructions on using regedit to get it to show up for editing. I followed the instructions and Wavelab is now listed in the tools menu. So I highlight a track I want to edit go into tools, click Wavelab and the Wavelab program opens but no wave appears. Any suggests on what I might have done wrong? Thanks all

You need Wave Lab 7 to run in 64 bit. You'll find this info documented at your Steinberg users form. Just upgrade to 7. 

  Thank you. Had a feeling that was the issue.

I solved the problem by purchasing Wave Lab 7 Elements for only $86 Can. ( on sale at Tom Lee )  It's pretty much all there for mastering and track wave editing. You really don't need all the features of the full version ( $400+) if you have Sonar. Your Sonar Plugs will work with in too!
