Hi
Once you have it installed and patched up, navigate to the TS2010 folder, and open the Built In folder. You should see the snc.ja file so make a copy of it and save the copy somewhere safe. In the event of having to reinstall at some point, or needing to add it to TS12 pre SP1, it will just be a case of copying and pasting the snc.ja file back over, adding the serial number and doing an EDR to get it all back in which saves quite a bit of time.
I have done the same thing with all of my pre TS12 SP1 DLC content and this method lets you install it all very quickly and just requires one EDR once it is all copied and pasted into the Built In folder.
