Here are the size totals for all 4 main folders having to do with Sonar X3:


C:\Cakewalk\Content\   -- 2,252 MB  (Audio Library -- 1,238 MB)

C:\Cakewalk\Projects\  -- only 39 MB
 
C:\ Program Files\Cakewalk\  -- 3,176 MB
 
C:\Program Files (x86)\Cakewalk  -- 1,277 MB

Total = less than 6 GB
 
 
Does that not make bells & whistle alerts go off in your mind?
 

Yes, this appears to confirm #9 above.

I do have 1740 rx2 files installed, 3/4 of them in the C:\Cakewalk Content\Audio Library\Loops\

The other 1/4 of them are in C:\Program Files\Cakewalk\Vstplugins\
 
So I guess my Loops & One Shots have been installed.

I don't think so. There is over 4GB of content in "Loops and One Shots" that is placed in "C:\Cakewalk Content".

Since I have some rx2 files, what do you recommend I do?
 
Can I attempt to run the 02 SONAR X3 Producer part 2.exe file (it was supposed to do this automatically and ask me if it did not find the next file) ?

Is there any danger in attempting to pick up at this stage and try installing files (even randomly)?

Everything is fine so far. No need to re-run the 02_SONAR series. The 03_Loops* and 04_Dimension* are separate installers.
 
Download
03_Loops_And_One_Shots.part1.exe
03_Loops_And_One_Shots.part2.exe
03_Loops_And_One_Shots.part3.exe
04_Dimension_Pro_1_5_Setup.exe
04_Dimension_Pro_1.5_Expansion_Packs.zip
 
then run
03_Loops_And_One_Shots.part1.exe
04_Dimension_Pro_1_5_Setup.exe
 
then unzip and install
04_Dimension_Pro_1.5_Expansion_Packs.zip
 
then apply the X3e update (see link above).
 

I did all this a couple days ago (the things you just wrote to do). I hope nothing goes wrong trying again.  

I suppose if it's a big mess, I can use System Restore point.


And I did run the X3e patch, and when I open Sonar and look at the About file, it shows X3e installed.

It is easy to uninstall, no need to return to a restore point. I believe the confusion is expecting the 03 and 04 files to install themselves by running the 02 installer. These are different installers which much be kicked off separately. The first one in the 02 and 03 files launch the others in their series. It is clear over 4GB of content and DimPro are missing. Both are separate installers.

Scook,
 
If I did already run the 03 and 04 installers, will there be any danger in trying to run them again?

Is the software smart enough to compare what it wants to do with what is already installed on the Drive?

No harm at all in running again. BTW, if 04 was run there would be a Dimension Pro entry in Programs in the Control Panel. If it were run and is not in "C:\Program Files\Cakewalk" then look in "C:\Program Files (x86)\Cakewalk". If it is there then the 32bit version of DimPro was intalled. It would need to be run again to get the 64bit version installed. There would also be an icon on the desktop for DimPro and the plug-in would be in synths. The Control Panel will also show if the DimPro Expansion packs have been installed.
