Just purchased this the other day and for the past hour I have been going through the Gibson EB5 installation hell also....so a timely thread.
 
In my case the samples are located here: 
C:\Program Files\Cakewalk\Dimension Pro\Multisamples\50 - Gibson EB5 Bass
 
Program located here:
C:\ProgramData\Cakewalk\Dimension Pro\Programs\Gibson EB 5-String Bass
 
But when I open DimPro, open the browser (and refresh with F5) there is no Gibson EB5.
 
So right now I'm stumped!

The exe files are in the folder with the dll
The default locations are
C:\Program Files\Cakewalk\VSTplugins\Dimension Pro
and
C:\Program Files\Cakewalk\VSTplugins\Rapture

Excellent. Thank you.
 
@Tunerman... Wish I could help you out more but I'm still muddled on it all and my brain will break if I try to even think about it until a good night's sleep.
 
But I was installing the freebie pack. Not the full pack from the Cake store so maybe the installations are different anyway. Good luck.

On my machine I found the paid version of EB5 in two folders under "03 - Real Basses" called "Gibson EB5 Bass Growl" and "Gibson EB5 Bass Pure." Maybe I moved them there I am not sure.

I checked the default paths you provided and mine are as you listed.

Longshot but you did extract the files, yes? Just thinking maybe you manually dropped the zipped folders.
 
/not helpful

8 folders filled with note names and 8 sfz files at this location:
C:\Program Files\Cakewalk\Dimension Pro\Multisamples\50 - Gibson EB5 Bass
 
So yes, I think they are unzipped...good thing to check though.

Yup... that sounds extracted to me. I'm all out of my non existent ideas.
 
I'm sure someone smarter can get you sorted. If it's the paid version you could of course give a call to support if all else fails. Toll free in the US.
 
Cheers.

Cold booted the cpu (along with Win updates) for a fresh start. Opened Sonar, opened my existing track with DimPro, browser and F5, and still no EB5 in the program list. Closed Sonar.
 
Found the DP program and ran it in stand alone, and lo and behold, the EB5!
 
I don't know....I'm ready to go the long way and re-download DP from CCC and start from scratch. Did this once already when CCC came out.
 
OTOH, I want to make some music now. If someone comes along this weekend I'm open to suggestions. For now though, I'm going to continue to use the available bass programs and contact CW support on Monday.
 
Thanks all!
