Hi Kaylen
It might be that the BFD2 installer didn't pick up the cakewalk vst folder (C:\Program Files\Cakewalk\Vstplugins) during the install.
Re-installing only takes half a minute as you wont have t reinstall the data, just the program.
Do you have a "vst" folder in your program files ? Something like, C:\Program Files\Vst or any Steinberg products that mean you have another vst folder ? If the answer is yes to either of those questions you could try and find the BFD2 dll file inside either folder and move it to cakewalk's vst folder, then run sonar's vst scan.
If that doesn't work then reinstall and pay particular attention to where the 64 bit installer wants to install and point it to
C:\Program Files\Cakewalk\Vstplugins.
Hope that helps
Steve
