Nina - your shared files workaround turned out to be unnecessary, in this case.
Steps:
1. Uninstalled every version of PD - 9, 10, 11 & 12
2. Uninstalled all Contents Packs & added extras
3. Uninstalled Director Suite 1 - PD11, CD, AD & PhD4
4. Uninstalled NBFX VE I, II & III
5. Cold boot
6. Re-installed Director Suite 1 & applied all updates
- all NBFX installed & displayed as expected - Paint, Art, Motion, VE
7. Copied/pasted "Shared Files" ready for swap
8. Installed Director Suite 2 & ran updates
- all NBFX installed & displayed as expected - Paint, Art, Motion, VE I, II & III
- no duplicates & no missing NBFX
9. Deleted folder created at 7.
So - my issue came down to the earlier installation of NBFX VE I, II, & III (from NewBlue). Without them, the installation of PD12 beside PD11 caused none of the previous issues.
Cheers - Tony
