Unable to register DLL error APRO.dll on win8 X2 install

Hey guys,

I just setup a brand new clean install of win8 pro and I'm installing Sonar X2. It's literally the 3rd thing I've install on this new setup. 

I'm getting the following error:



I'm running the install using admin privs. I'm on win8 64bit installing sonar x2 producer 64bit. This same installer worked fine on win7. I'm installing using the defaults, except I've added in the vstudio files as well, since I have one.

Any help? I was hoping to get this working tonight and over the weekend. I'd like to avoid having to do a support call on Monday :(.

Thanks!

Josh
