IE 8, Yikes! What have I done?

I run Win XP Pro, and just installed IE 8 Beta. Since that I cannot open IE. It opens for a few seconds and promptly closes before anything loads.
I re-downloaded IE7 which worked fine before this and the same thing happens. It too opens and promptly closes also now.
I only us IE for doing MS updates otherwise I use Firefox.
I did install Google Chrome just before that and IE apparently disabled that too because the .Exe file for Chrome disappeared. I have since re-downloaded and installed that and Chrome works fine again.
Anyone have any idea how I can get IE to work so I can do my updates.
Thanks.

I think the IE8 beta 2 has some promising looking things in it.

That being said, I only have it installed on a virtual machine with undo disks enabled. I'm not about to trash my OS for a browser.

 

Google Chrome does seem to work great.
It is good that you found a way to fix the missing installation but the Google chrome installation is located in your user account folder under "appdata" after that click "local" then "google" From there you should be able to find the exe.

 

I think you got the wrong thread... :confused

 

Thanks to all for the help and suggestions. I read somewhere that SP-3 might be a problem. I had SP3 installed for a long time. Downloading IE8 was the problem.
I couldn't uninstall it because it didn't show up on the list. Here is what I did to fix it.
1.Uninstalled SP3
2 Reinstalled IE7.
3.Reinstalled IE8.
4.It then ran OK.
I then did a Windows update and installed 13 updates as instructed. SP-3 was not on the list.
Everything now seems to be working just fine including Firefox and IE8. Don't know what happened to SP3, but I'm assuming I no longer need it as it doesn't show up on the updates list.
Once again thanks all.
