Would Like To Say Thx to those that offered solutions to this fix of MSE not updating on XP SP3.
I was using 2.11 had this problem on 2 PC's with error code 0x800700c1, resulting in not updating Auto & either manually
I updated from 2.1 to the latest it can take (I think 4.4)
used the PE_Patch and changed header as suggested from 5.2 to 5.1
and it worked like a treat
So far it is now working, instead of a red or orange Icon it is green, & trying the auto update also works
NOT sure if it is a stuff ip on M$ part or deliberate, i had , had a similar problem before
