If you have MS Front Page 2003

Open "add/remove programs", select "MS Front Page 2003" and click "change" button. Now chose "Add or Remove Features" and click next , there expand "Office Shared Features" and click on "Microsoft Handwriting Component" and select "Not available" and click "update". If that's no help then expand in the same tree "Alternative User Input" and do the same for "Handwriting" option. I can't now remember which is one of that two guilty because I have them both uninstalled. After this there is no more that WISPTIS.EXE and MS installer.
