    I downloaded the 45-day trial of the Virtual (t-v) PC 2004. With
    satisfaction I purchased the nontrial version to install on my Windows XP
    SP-1 pc. When I tried to installed the non-trial version (n-tv) I got a
    Fatal Error - Installer must exit window with the message saying. You must
    uninstall previous versions of Virtual PC Trial before installation. This
    application will now quit.

    So I did just that using the Add/Remove programs in CNTL Panel to remove the
    app and even removed all entries of the t-v in the registery with the same
    results. Can someone help me so that I can install this application.

    I did as you requested and rebooted the workstation, but now I get this error:
    Error -1607: Unable to Install InstallShield Scripting Run Time

    I tried the links as you suggested and sorry to say I'm no closer to
    resolving this than before. So I tried restoring my OS from a image to start
    the process again. I uninstalled the trial version of VPC and rebooted the
    computer. Once that was done, I tried to reinstall the bought product and
    got the Fatal Error - Installer must exit window with the message saying.
    You must uninstall previous versions of Virtual PC Trial before installation.
    This application will now quit.

    Am I still missing something?

    Hi Craig,
    I would like to suggest you to try out this link and download the WIndows
    Installer Cleanup utility.
    When you run this utility it would show a list of Installed packages on the
    computer. and there is a option to remove the packages which do not have
    their registry entries completely flushed. I have a feeling that the
    uninsallation of the trial version of the Virtual PC is not removing some of
    the registry entries and the full version checks for those entries and tells
    that you have to uninstall it.

    So use this utlity to flush any remaining entries and then try to install
    the full version. Hope this information helps.

    I downloaded the Windows Installer Cleanup utility as you suggested. After
    installing the app I restarted my PC and launched the application. I went
    through the entire list of applications available for clean-up and
    unfortunately the Virtual PC software was not part of that list. I tried
    reinstalling the trial version again rebooted then ran the Clean up utility.
    It did list the application, I ran the clean-up against it and noticed that
    VPC Trial version was still listed under Programs, but it was not listed
    under the Add/Remove programs in the CNTL Panel. Again I tried to install
    the retail version and came up with the same Fatal Error as before.

    I finally got a solution after talking to 3 different MS Tech-support people
    over the phone. First I uninstalled the VPC 2004 then I had to go into
    'REGEDIT' and branch down to thru the following trees:
    Once I got to this section, the right portion of that window shows the REG
    types and one of the entries there said "Microsoft Virtual PC 2004 Trial". I
    had to delete the entire registry entry. Mine was labeled
    {279D84F-4FB6-B0BB-0B81C053F210} it may be different for others because the
    1st phone support tech told me to look for a different register entry (could
    have avoided the extra calls if he had told me just to search for "Virtual
    PC" as oppose to a specific entry).

    Anyway that was my solution. I hope this works for you. No one should have
    to go thru all that.
