How do I know what version of Dimensions I have on my pc- I purchased the program several years ago and then it came with my SONAR X upgrade... I think I downloaded the expansion pack and the upgrade when I upgraded to Sonor X lastbyear, but I don't remember because I was not able to use my computer for about a year.... And every time I try to install via the link on the cake sureI get a message saying I have the wrong version or something to that sort!

Locate the dimpro dll in your vst directory. In my case I am running the 64 bit version of DimPro, the dll is called "Dimension Pro x64.dll." Right click on the dll and view Property > Details.
File version 1.5.0.11
Product version 1.5.0

K thanks

Just for reference, an even easier way to see the version, just click the "Dimension Pro" logo on the program panel and up pops the "about" with the version number.

Same thing for Rapture, Z3TA, and others.
