LTK Demonstration
  • Problem: Error code 75 Path/File Access Error when running the LTK Demonstration program.
    Solution: This error occurs when a Windows user does not have administrator rights. The LTK
    demonstration program requires administrator rights to perform the installation and cannot be run
    by another Windows user on the same PC.

Common Problems (LTK Versions 7.x and earlier):  

  • Problem: Error message: Schomenu (or Homemenu or Kidsmenu) caused a General Protection
    Fault in Module VTSSDLL.DLL at 0004:0260 when attempting to print to an HP printer.
    Solution: HP has created new interfaces that support Windows® Vista® operating systems for
    their printers. Their drivers that support both XP and Vista cause this error on XP systems but
    work fine on Vista systems. To eliminate the error, add your existing printer a 2nd time to the
    LTK Student PC. Then change the driver for it (do this by selecting the printer
    Properties/Advanced). Change the driver to HP 4P or to HP 4. Then change this printer to be your
    Default printer. You can now select any printer when printing LTK reports.

  • Problem: I can't hear what's been recorded using the LTK® Record button.
  • Problem: The LTK screen is incompleteit appears that only the upper left portion of the screen

    your mouse on the Windows screen, then select Properties/Settings/Advanced.

  • Problem: Message "Invalid Dynamic link to DLL File." is received when LTK is started. This
    situation is rare and occurs on a small number of PCs sold since March, 1996 that have Windows
    98/Me pre-installed. The cause of the problem is related to installing the OEM version of Windows
    Solution: To resolve this problem, re-install Windows 98/Me on your hard disk, or upgrade to a

  • Problem: On certain IBM® Adaptiva® PCs, LTK appears to "hang up" the PC when it starts. The

  • Problem: My computer is not able to read the LTK CD-ROM.
    Solution: If your PC is more than 5 years old, your CD-ROM drive may not be able to read CD-
    ROMs that are burned by another PC. All of our CD-ROMs are burned (not stamped by a
    vendor). To resolve this problem you will need to replace your CD-ROM drive with a newer one.
    They usually cost about $30.00 at any computer store.
