Sorry, i understand my mistake . CLR2 is also .Net 3.5 and clr 4 is .net 4.

Thanks

Vincent

Thanks,

Should be .Net 3.5 i try on a windows 7 and a Windows Server 2008, still don't understand what i did wrong.

Hi, Thanks

But i install it and restart my instance and my clr version is still 2.0.50727

I user clr.exe and select * from sys.dm_clr_properties; to see the version.
