I am trying to install Framework 3.0 but everytime i try to install it fails because important files are missing i searched but i cant find solution or i dont understand it
 
Solution
"Framework 3.0" is not enough of a description to even start debugging. Do you mean Microsoft .NET Framework? Is this a purchased product? Can you get new install media from the vendor?

Yes, for the Microsoft .NET Framework. Like i want to install Sony Vegas and it needs Microsoft .NET Framework 3.0, i had 4 and 2 but i deleted them and now i am so confused what i have to do
 


You might want to read the Microsoft article on compatibility between .NET versions. You may be able to use the 4.5 .NET version.

Here is the compatibility between OS versions for the different versions of .NET.
 


Now i am more confused.
 
I had .NET Framework 3.0 with the computer but days ago i installed Ashampoo 12 which wanted Framework 4.0 so i installed 4.0 and i wasnt able to work with Vegas, so i deleted it and when i tried to install it said it wanted Framework 3.0 and i clicked on the Install button and it popped a window saying that i am not connected to Internet, but i was connected and yeah my problems started then
