Setup BD-RB with Win 7

[Capsbackup]

My curiosity has done me in!
I wanted to see if I could run Windows 7 on my I7 920 computer, and after running the Win 7 update advisor, it warned me there could be some conflicts. The challenge was on.
I decided to try the Ultimate edition RC, since it was free, and if I did not like it or it did not seem worth the upgrade price, it would expire soon enough and only a few hours would be waisted. ( waisted plenty in my time! )
Well, all installed fine, and after searching around for updated drivers for some hardware, all was a go.
Now trying BD-RB, all is not so well.
I can't seem to get it to even start up, I get this error:
"Component MSCOMCTL.OCX or one of it's dependencies not correctly registered: a file is missing or invalid"
I try the fix - "Look in the BD-RB folder. There is a .BAT file called "REG_MSCOMCTL.BAT" -- simply right click onit and run it as administrator."
But then I get this - The Module MSCOMCTL.OCX failed to load... So this does not work for me.
Can BD-RB run with Windows 7 RC?
How else can you get rid of this MSCOMCTL.OCX REG issue just to get BD-RB to start?
After reading back numerous pages, I can't seem to find out what to do next. Any help is sure appreciated.

EDIT:
OK, I got it to work by right clicking on BD_Rebuilder and selecting "Run as Administrator", which it then set up ffdshow for me, and now it starts up.
Off to try out a backup!
