I have all the .net frameworks from 1,1.1,2,3,3.5, and 4 on my Home XP. I can go into add and remove programs and repair all of these by clicking on the change button except for 1, 1.1. Is there a way to repair these 2 without having to re-install them I always run into a lot of problems if I have to do that. Like, does Microsoft have a place to go that checks all your .net frame work installs and then repairs the ones that are bad? Thanks for any help... P/S..Net frame work 1 and 1.1 don't offer the change option, only a delete option.... Each time I reboot my computer a handling exception error will pop up about .NetFrame Work. As far as I know it doesn't say which version the error is from but I have used the change button to restore all of them except version 1 and 1.1. i still get the error so I guess one of them needs a repair. Thanks....
