Reflector does not open in VS2008

Reflector fails to open when I use "Open in .Net Reflector" command in VS2008. I tried several types, members, assemblies, without success.

I upgrade Reflector form 7.1 to 7.4.1.193. I have a valid license.

I try some things I readed in this forum. For example:

Debugging Visual Studio, I see this exception:

System.IO.FileNotFoundException
