I did a clean install of Windows 7 32bit to move up from Vista 32-bit.  I Reloaded Sonar X1 (and X1 expanded).  Installed Dim Pro 1.5.   Opened it stand-alone as Administrator and registered it.   
 
In Sonar I can see it in Insert Soft Synths and when selected get the Insert Soft Synth Options pop-up but when I click OK I get "Failed to insert soft synth.  The synth may not be properly installed."
 
I then uninstalled Dim Pro 1.5.  Cleared Regedit of all traces.  Removed Dim Pro from System/Program Files/Cakewalk and reinstalled.  Got the same message again.
 
This is very frustrating.
 
Any help?

Have you double checked to make sure your VST scanner is pointed to wherever the Dim Pro files landed (maybe it's trying to access the LE version)? Have you tried the plug in browser thingy and hitting F5 (I'm not sure exactly how that thing works but I know I've successfully found things by doing that)? Was it a download you installed from? Maybe the download got corrupted. I can't remember whether Dim Pro shows up as a separate download or not but if it's in your store account maybe try downloading it with a download manager or FireFox and try again. I'm sure you've already covered some of those options since the last thread but that's all I can think of. If it just ain't working I'd give Cakewalk a call and see what's up. Very strange situation. Good luck.
