Have you installed the Fiji TV-pack? That might be cause the problem.
I found a possible solution in a swedish forum (http://www.minhembio.com/forum/index.ph ... &p=2031260
That guy says that you could try (AT YOUR RISK OF COURSE) to change this Registry key:
Change the "Ident" key from "5.1" to "5.0".
I have not tried it myself though, but that might fool the installation program (which obvisouly needs to be updated).
If it works I suggest that you restore to key to the original value afterwards.
