Installation problems with ASP MVC Release Candidate 1

I've tried installing RC1 must have been 5 times already and always run into the same issue around the "Configuring Templates' step. I've tried everything I can think of but now I have neither RC1 or Beta. Has anyone run into this error? Any suggestions for what I can do?

Screenshot of my problem here (not sure why I can't place it as an image.

(Cross-posted to the ASP.NET forum here but I don't really expect much of useful response there.)

Edit: Here is everything I can think of that I have installed that might possibly be affecting this: Coderush, Refactor Pro!, Source Outliner, TestDriven.Net, MbUnit (installs some templates), Some DevExpress plug-ins (GhostDoc, CR_Classcleaner), F#, Spec #

I have also installed (and uninstalled) ASP.NET MVC Beta

From stackoverflow

• You don't state explicitly, did you install any other previous versions (such as beta or preview)? You will need to uninstall Beta or Preview x before installing the RC.

  George Mauer : I did have Beta previously and I uninstalled it first (It wouldn't even let me install while Beta was on there) I have double and triple checked this.

• After the obvious step of removing any older installations of MVC, I've heard the templates can have issues with Visual Studio add-ons. Try removing any add-ons to VS you might have running, then run the installer.

  George Mauer : What, really? That is a major hindrance, I've got Coderush, Refactor Pro, F#, Spec #, Source Outliner, and a couple Developer Express plugins. This is a pretty massive fail, now I have to weight playing with ASP MVC versus this huge bother.

  Chad : Yea, I don't use any add-ons... so not stating from personal experience. Just from what I read. I doubt its ALL add-ons... more likely only certain add-ons (but which, who knows. ;D )

• Just happen to run across this... do you have Clone Detective for VS installed? Seems as though some people had trouble installing the MVC Beta with it installed.

  George Mauer : No I don't and MVC Beta installed (and uninstalled) with no problems

  zonkflut : This solved my problem :) All good after uninstalling CloneDetective.

• For the record, it was either F# or Spec# that was giving me problems since I don't really use either much I uninstalled both and RC1 went fine.

  Loren Segal : Thanks! I can confirm that removing Spec# solved the install problem for me.
