I upgraded to IE8beta. I also installed SP3. Since then I've been
getting the following error when attempting to start IE8beta:
---------------
iexplore.exe - Application Error
The instruction at "0x5a913420" referenced memory at "0x5a913420". The
memory could not be "written".
Click on OK to terminate the program
Click on CANCEL to debug the program
----------------
When I try to uninstall IE8BETA I get a message saying it cannot be
uninstalled. When I try to install IE7 over the top I get told that I
can't install it since there is a later version already installed.

Firefox works okay. However I tried the new Google Chrome to see if it
works and it gives the exact same error apart from the iexplore.exe is
chrome.exe.

I'd be glad of any help with this problem.

Regards

Tom
