A short one this.
I've just been attempting to install SQL Server September CTP. I uninstalled the previous version and also the the previous version of Visual Studio.
When I tried re-installing Visual Studio I got a message saying that Microsoft Device Eulator was still installed. Looked in Add/Remove Programs and sure enough, it was.
Except it wasn't, it wasn't anywhere to be found in "C:\Program Files" so trying to uninstall from Add/Remove Programs of course failed.
To fix this I searched through the registry for "emulator" - anything that it found I deleted.
I've kicked off the install again and it seems to be working OK. We shall see!!
Oh and by the way I'm doing this on VirtualPC which when you start messing about with the registry is obviously a good idea!
