Question : IE7 wont open

Hi

I have a client who's computer is playing up after suffering a number of power cuts in the area....

To cut a long story short, they were experiencing various problems, including the active desktop was playing up.... so I figured that I would upgrade to IE8 whilst I was there as it is a better browser than ie7... IE8 failed to installl correctly, so I rolled back to IE7 and now that wont start....

 IE7 appears, then immediately disapears.

I have tried to start with no extensions, and have tried to start with a blank page but nothing happening....

I though, I will reset IE7 from #internet options' in the control panel.... but that is now gone! eek!

Any Ideas What is happening and how I can get IE7 to function again?!

Cheers

Answer : IE7 wont open

There is a proxy present, possibly hidden somehow:

R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyServer = http=127.0.0.1:5643

Scan that machine with Hitmanpro
