fixed it - yea!!!!!
even though it didn't ever finish installing, I just closed CCC in the end ( whilst it was apparently still installing) but on reopening Platinum it had no appeared in the VSTs
lets hope it works
I was also going to suggest to make sure you are running your CCC as administrator as well as other installations.
you will avoid countless headaches in the long run by making sure/ verifying you are running installs as:
right click/run as administrator.
it doesn't matter if you are the administrator, bla bla bla.
its a windows feature that started in windows 7, a safety net if you will.
Microsoft holding your hand.
any who, glad you got it sorted out.
