I just upgraded from Sonar X1 to Platinum yesterday and I've installed everything now but the old Cakewalk and Sonitus plugins are nowhere to be found. I believe they're still included from the feature list I read, but I'm not seeing them. I really need them as all my older projects make heavy use of them. Is there something I'm missing?
 
I did install 64-bit this time. I had X1 installed in 32-bit because at the time I couldn't ReWire into Reason 6 in 64-bit. That's not an issue now. I don't think this has anything to do with it but...I just don't know. What can I do?
 
EDIT: Never mind, I found them. But nevertheless, when I open an older project made in X1 it still marks the Cakewalk and Sonitus plugins as unavailable and missing.

There are 64bit versions of the Sonitus plug-ins which should be installed with Platinum. Old 32bit DirextX plug-ins are not installed because they will not load into 64bit SONAR. To open old projects which rely on 32bit DirectX plug-ins consider installing the 32bit version of Platinum or continue using the existing X1 installation while transitioning to 64bit.

I made a mistake, the Sonitus plugins are there, but it's the Cakewalk Fx plugins (FxChorus, FxFlange, etc) that are missing. No way to get them to work in 64-bit then? I thought the bitbridge took care of that, but I guess that doesn't apply to DirectX plugins? I didn't even know they were DirectX plugins. I assumed they were VST like everything else...oh well.

Bitbridge works with 32bit VST plug-ins only. DirectX plug-ins are host specific and Cakewalk did not port the Fx series to 64bit. It is possible to wrap 32bit DirectX plug-ins in software which presents them as 32bit VSTs to Bitbridge but it is not a good idea and I do not believe existing projects will recognize the wrapped plug-ins as the DirectX versions in the projects.

Thanks for your help. :) Luckily I haven't used the Fx plugins near as much as the Sonitus ones so it won't be too difficult to go through the old projects with X1 and use alternatives before using in Platinum.
