I am unable to install the EPiServer Visual Studio integration for CMS R2. After a first "pass" of the progress bar in the installer, it stops close to zero, and about 20 seconds later it just disappears. No error message and not a trace in neither visual studio nor add/remove programs. If it matters I have VS2003, 2005 and 2008 installed, 2005 with the old CMS integration already in place, but I want the R2 integration in VS2008. Anyone experienced anything similar?
