Having some problems getting unrar.dll working.

[DukeBlazingstix]

I've used unrar.dll for a while now in WindowsXP to add unrar capability to my application; I pretty much just threw RARLab's sample code into my app, and it worked no problem.

A while back, I moved to Vista Beta2 x32, and I had to open up a command prompt as Administrator and regsvr32 unrar.dll to get my application to recognise it.

Now, though, I'm running Vista RC2 x64, and it won't let me register it for the life of me. Can anybody help me do any of the following: register unrar.dll with the system; have my app call unrar.dll without registering it; find an alternative to RARLab's unrar.dll that will work in Vista x64?
