I have been using Session Drummer 3 for a long time and since I have installed X3 producer it fails to load. I have done 3 reinstalls and the patch and still have problems. Help!!!!!!!!!!

"The following VST plup-in failed to loadc:\program
files\cakewalk\vstplugins\Session Drummer3\SessionDrummerx64.dll"
 
after I close that window then:
"Failed to insert soft synth.
The synth may not be properly installed."
 
As I said before I have reinstalled 3 times and applied the patch.

Try closing SONAR, right clicking on the icon for SONAR X3 and selecting "Run as Administrator". Did this clear it up?

I tried this and reinstalling and still not working.

I had this problem and I tried everything anyone told me, but it still didn't work.  I tried uninstalling X3 along with deleting the reg entries, I tried the resetting and rescanning of my VSTs and that didn't work.  The only way I did get it to work was to go into my VST plugins folder  (C:\Program Files\Cakewalk\VSTPlugins) and delete the folder named Session Drummer 3. Then I installed Sonar X2  and only selecting the Session Drummer 3 VST plugin to be installed.  I unchecked everything else.  When I did that and let X3 rescan, Session Drummer works.   I don't know if you have X2 or not, but if you do, it may work for you.  
Surely, there is another way to fix this, but I couldn't find it.  It seems that the overwhelming majority don't have this problem, but some of us are.
By the way, the Session Drummer that X2 installs is not the same file size as the one X3 installs and I have never found out what the difference is.  Anyone know ?
 
I hope this may be of help to you and would be interested to know if it works for you.

I had same problem. And  already opened a topic for this.

I have already tried what has written in the link attached by Dan Gonzales . Now it has completely lost !! Session Drummer even not in scanned VTS's anymore.
 

I have tried this, too. No dice.

I finally got my Session Drummer 3 back. I did what  said and it worked. I installed it from my Sonar Producer X2 the 32bit version. It works fine now. Thanks Rloseven!!!!!! Your the Bomb!

When I did that it not only didn't replace Session Drummer but lost SI Drummer and Amp Sim.
 
Trying another install of X2a 64 and only clicking on Session Drummer (assuming that the program files should be installed - tried unchecking every single thing in that part of the installation apart from SD last time). 
 
I should also say that I downloaded X3 on two times on different days. Could I really have dl-ed a corrupted file both times with the same ommission of SD?
 
I had SI Drum kit taken out of a previous attempt as well and in the confusion of trying everything I could think of over days I reinstated it I think by reinstalling X3 and the b patch. Anyone else?
