To whoever might be interested:

Without any apparent reason my Internet Explorer 8 running under WinXP SP3 started
to improperly show various pages. I quickly discovered that Javascript did not work.

Reinstalling IE8 did not help though, in my opinion, it should!

Long and extensive searching on the web did not help either. All tips how to (re)activate
Java Script [by changing security level in Internet Options and activating scripts]
did not work.

I went for total removal of IE8 and reinstalling it from scratch.
I failed:
– IE8 was not visible on Add/Remove Programs screen
– Directory Windows\IE8 where ‘spuninst.exe’ uninstaller is located was not present.
– Microsoft ‘fix it’ tool MicrosoftFixit50238.msi refused to remove IE8 because
it was blocked by some updates.

What I had to do?
1. Create a restore point
2. Try to carefully remove IE8 manually. I would probably mess up the system.

Creating restore point did not work either! I got a blank screen.

Back to Google search… and BINGO! There was an answer:

I had to reregister two DLL-libraries:

regsvr32 jscript.dll
regsvr32 vbscript.dll
