I am running windows 7 64 bit.
I recently had to deal with a bad install of SQL Server and just wiped the hard drive and started fresh. So i don't want to repeat any mistakes I might have made, one of which might have been running multiple versions of aspnet_regsql.
This file exists. in 4 places on my computer. 2 for 32 bit and 2 for 64 bit.. and within those, one is for 2.0, 3.0 and 3.5 and one is for 4.0
So should I run each one? Do I need each one?
