Sonar 8.3.1 32 bit to 64 bit VST issues

The 64 bit version of SONAR stores the 32-bit versions of VSTs in a different folder marked (x86). They should automatically involve the JBridge adapter program when inserted. AFAIK there are some VSTs, though, that don't like 64 bits.

I'm not dead sure about 8.3 because I missed that version and went right from 7 to 8.5. 
Later when I switched to W7 64 bit I installed the 64 bit version and most everything automatically worked without issue. I think there was just one 3rd party reverb that didn't. 
SO for me it was seemless. 

Might be a 8.3 bug? 

Just an update for anybody following or having similar problems.  I looks like effects like Reverb XL were things that came with SHS4 (or 6) XL. Not a big deal. I think I can just Kill that instance of the effect and reload the one that came with Studio 8. Probably better anyway. As for the missing synths like DYAD DXi and Triangle II, they were probably on those HS4XL install discs as well. But..... Triangle is downloadable from cakewalk for free and it looks like DYAD is going to require me to dig out the old  HS4XL install discs.....or is it? It appears for whatever odd reason I saved the DYAD DXi soundset on another drive. Its my understanding I can use them with SFZ+ and while the interface might not be as nice it should actually be more powerful. So me thinks we gots this solved. Thanks for the help.

OK so next update......It's always easier in theory isn't it! So SFZ+ was...... Eh......not a great solution. It had latency and memory issues. Try to load a 72mb file it says not enough memory. WTF? I got 16GB ram how could this thing not have enough memory? So dig in the forums. Seems this is a buggy thing Cakewalk has no intention of fixing since it been discontinued. OK I get it. So I tweaked the latency setting and got it to play smooth but only loading the smallest samples. So that ain't really gonna work let alone trying to find the same sounds used in Dyad. OK, so into the garage and pull down the box of old software. Surprise! SHS4XL was right on top. Cool! Now I have the install disks so I'll just load up all that old stuff and be done with it. Pop in the install disk. It allows me to install only the components I want. Meaning If I don't check the program files it won't install SHS4XL and I can check the DXi Synths box and the effects box and it even lets me pick exactly which ones and if I want to install all the sound content for each one. Awesome! So I install just the items I want. Reboot the machine and open Sonar 8.3.1. I go to tools, Plugins Manager, set the path for all the stuff and run the scan. Suddenly I'm getting "Program can't start" errors because of Missing CWDXPX1.DLL. WTF? How can installing a DXI synth jack registry information? Anyway Nothing works right and Sonar still can't find DYAD even though it appears in the list of soft synths. So "F" this. I'll uninstall everything and re install starting with SHS4. But first lets check reaper and see if it works. Sure enough, same issues. So I install SHS4. All is cool everything works. It sees and plays DYAD etc. However I'm still getting some CWDXPX1.dll errors when trying to load the newer VSTi's. So I'm thinking the upgrade to 8 will take care of that. I install SS8. Reboot and do the 8.3.1 update. Upon launch I get a ton of errors. This time CWDXPX1.dll and PNCRT.dll. It says to "re install the software". Here is where I prove Einstein was right in that Insanity is doing something over and over expecting different results. So I prove his theory about 5 times. By this point Sonar is totally "F'd" runs but all kinds of problems especially with soft synths, latency etc. Hmmmmmm what about Reaper? Yep, exact same errors with Reaper. BUT I notice there is an update for Reaper (Because Cocos throws out updates like every 15 minutes) so I do the update. Reboot, Launch Reaper. Low and behold Reaper works perfect. Not a single error, runs the synths and everything. So I'm thinking, OK that install fixed those .dll registry issues and Sonar should run now. Wrong. Reaper can find the files but Sonar still says they are missing.......OK "F" this. I do a system restore to a few days earlier and here I sit right back at the beginning.
I agree with Cactus Music. This should be as simple as dragging the dyad.dll file into the DXi folder. Problem is that file doesn't exist on the install CD's. It's stuffed into some Cab file that the installer has to unfold. FORNICATE! This should be easy.

Yes Cactus, I was thinking the same thing. Time to build a nice Little Win XP Pro Legacy computer. Good news is that I kept my old Hardware. Should be easy enough. But you're right. What a PITA. OK so one more thing to add to the To Do List. Sigh......
