Ado.net entity data model template missing in visual studio 2010

Environment: Vista, VS2010 SP1

Apologize if I seem to be repeating this but I have spent a day on this. Last ditch attempt before I reinstall VS2010!!

I tried 1. devenv /installvstemplates 2. uninstalled EF 4.1 and installed 4.0 CTP 5 and now it's not even opening VS2010. Asking me to install SP1 again!! I used Web Platform INstaller to install SP1 and EF.

Most of the posts was on VS2008 and differen开发者_C百科t scenarios. SO really not sure what happened here.

Thanks in advance for your time
