MS Net frameworks various
 

Trying to 'catch up' on MS Updates on No2 son's machine following major virus surgery plus update to SP3. He has net Fr 1.1 and 2. I have downloaded 3.5 and installed now. Can I remove 1.1 and 2? We cannot get a 'required' update to 1.1 or 3.5 to install properly.

I see Aaaron Stebner has a clever programme for sorting out issues here.

I also appear to have net 1.1, 2, 3 AND 3.5 (greedy!) Do I keep them all or what do I need to do? WHY do they not uninstall old before updating to a newer version?

I see dire Google warnings about some 'registration cache' issues too, which go over my head!

A 'security update' to SP3 is also failing. Is this associated?

I had a mix of versions on my XP Pro setup (I remember 1.1, and something in the 3. series). I never worried about 'em.

I was very careful to prevent XP SP3 from installing, having heard horror stories about it.

XP Pro has gone now - both Windows machines are on Win 7 and working fine.

Yes - I know the stories. It runs fine on my machine at home. so I thought.....................

We'll see. Biding my time on 7.

RE net frameworks - the MS advice I have now found is to keep all from 1.1 upwards as various programmers will have used various frameworks to write their stuff.
