    While opening 'Add / remove software' I don't see the list of programs
    instelled but a messagebox instead, containing:

    ************
    Title: Add/remove programs
    An unexpected error occurred.
    Class not registered
    res://appwiz.cpl/listbox.htc
    line:225
    *************

    Obviously the registry has been damaged. How can I repair this?

    PS I'll post a SECOND message in this thread containing screendumps

  2. Hi

    From the "Run" box try

    regsvr32 %windir%\system32\appwiz.cpl

    and
    regsvr32 %windir%\system32\webvw.dll

    and
    regsvr32 %windir%\system32\mshtml.dll


    If this doesn't help, in the German newsgroup, one person fixed the
    same type of error by reinstalling IE

    The article above also tells you how to repair Internet Explorer 6.0


    See tip 6032 at http://www.jsiinc.com/reghack.htm as well

    If this doesn't help, try to reinstall the OS service pack you already have
    installed (or install a newer one if possible).


    If the problem persists, you'll could do an in-place upgrade of the OS and see
    if it helps:
