I have not had any issues using philharmonic in 64 bit X3 and have not needed JBridge. I just installed it and it worked so I can't be too helpful on trouble shooting but there should be a resolution.

I'm going nuts with this.
I ran Miroslav in Windows 7, 64 bit, Sonar X3e for a year. No problems at all, no bit bridge, no JBridge, easy.
Computer crash. New computer. Nightmare.
I upgraded: Windows 8.1, 64 bit, also took the opportunity and upgraded to Sonar Platinum.
I think I finally have everything (that I really need, anyway) working.
Except Miroslav.
Tried installing in compatibility mode.
Tried installing in Programs (86) vst, in regular Programs folder vst, in the default IK media folder.
Tried copying the dll and ini files into different folders (as suggested above).
I checked my scan paths and I am scanning everything that Miroslav shows up in.
Uninstalled and re-installed this so many times, I can do it in my sleep.
I contacted IK Multimedia, and they were useless, just telling me to run as administrator. I replied to them, but my expectations are low.
At this point, I would have been better off just wasting more money and buying another program.
I'm disgusted.
Any help, please?

If you ran Miroslav in X3e without BitBridge, you must have been running the 32bit version of X3e. The plug-in is 32bit and requires a bridge to run in 64bit hosts.
 
By default installing SONAR Platinum using the Command Center will install 64bit SONAR. To run 32bit IK software in 64bit SONAR requires SONAR to run as administrator. The other option is to manually run the SONAR installers and install the 32bit version of SONAR.

You probably already know this, but did you do a VST reset AND re-scan, and install the latest IK version from their web site?

It was definitely running in 64 bit, so I guess I must have been using BitBridge (I'm guessing now that that happens automatically).

Yes, reset and re-scan and I went back to the website and I have the only version that I know of--as far as I know, it hasn't been updated in years.
 
I have it to the point where Sonar is seeing it listed under VST 2 as 32 bit.
 
It even appears to load, and for a second the welcome screen pops up, then quickly goes away.  If I try to call up the properties and GUI by double clicking, or clicking properties icon, Sonar freezes and crashes.

Not sure if this will be of any use to you Jones082, but if you happen to have Sampletank 3 (which is 64bit), the Miroslav library can be loaded into it as a legacy instrument thus avoiding 32bit woes altogether.

Thanks-but as far as I know, it won't work with free version and I can't see dropping another $100 just to get something that I already paid for to function. Is there anything else free that I could load the library into?

Not that I know of. ST3 is a huge improvement on ST2.5 so you would be getting that as well:)

It was working for me, but its now stopped. It was sometime ago I last used it in Sonar so I am not sure at which point it stopped working. I have just tried using JBridge and that seems to work. even though I got an error message. I need to play around a bit more when I have some spare time.
 
You can get a demo of JBridge to see if it solves the issue for you.

Following the 2 threads attentively 'cause I was about to push the button when I thought I'd check the forum for issues . I'll review after a night's sleep.
 
Cheers  for everyone's input.
