I "upgraded" to X2 via online download. I think it was 4 files that are now unzipped and stored on my backup. I am missing Studio Instrument Bass synth among some other things that I believe were supposed to be included. Were they in these "main" files or in the "additional content/welcom pac" downloaded files? How can I find/reinstall these from these downloads without affecting my program in any other way? I am in the middle of a recording project and I don't want to loose anything. I am 64 bit so when I made the change to that I lost many plugs and stuff but I still am fuzzy as to exactly what I should and shouldn't have. I wish Cake would have a complete list of what(plugs ,instruments etc.) I should have to use when running 64 bit.

Details of included content are here:

So all of that stuff works with 64 bit??? What "download includes the "studio instrument" stuff?

You can run a custom install, exclude the main program files, and select any missing instruments for install, by making sure to check the boxes next to them.  The same goes for effects.  Please note that anything not 64-bit will indicate so next to the component in question.
I believe the additional content is demo stuff - you can expand that out and review items within it for installation prior to committing to actually installing anything, so just run it and see what opens.  I would do so after first running the main install and selecting any missing components.

Hope that helps,

Here's the disk contents:

Everything except the extra loops and Dimension Pro (full version) are included on the main disc set. (Parts 1-4)

Pretty sure all the included Cakewalk instruments are 64-bit.
The built-in bit converter seems to be doing a pretty good job of managing and running most of my 32-bit instrument plugins so far! :)

Thanks!

Hey - sound - if you get this all working, please post back on that, so the next set of folks with this problem can see whatever worked to fix it.

Thanks, and good luck,

Glad you asked.  I have the same question (I think):  After doing a normal install of Sonar X2 Studio, I get a list of twenty synthesizers when click Insert > Soft Synth; but four of them don't come up - I get a message saying "Failed to insert soft synth. The synth may not be properly installed."
 

Which ones are not coming up with that failure message?

I had this exact problem in 2010 with the Studio Instruments, not just the bass, but all three in that group. At first I thought it was a bad vst scan but that didn't help. My solution was to do what Robert suggested above and do a custom reinstall just hi-lighting those instruments. Everything was fine after that.
