Error during think-cell (un-)installation

Problem

When installing think-cell, the installer automatically tries to uninstall any think-cell versions you previously installed. If uninstalling the previous installations does not work, updating think-cell fails.

  • If you see one of the following messages when installing or uninstalling think-cell, refer to Solution 1:

    error when installing new think-cell version. error when uninstalling existing think-cell version.
  • If you see one of the following messages when installing or uninstalling think-cell, refer to Solution 2:

    error when installing new think-cell version. error when uninstalling existing think-cell version.

If the installer program does not start please refer to KB0003.

Solution 1

In this case, Windows lost necessary information about the previous installer. The current think-cell version provides the missing information to remove the previous installation and installs the new version afterwards:

  1. Please download the current think-cell version from our download web page.
  2. Start the installation and the following message will appear:

    error when installing new think-cell version.
  3. think-cell provides the missing information in %LOCALAPPDATA%\think-cell\cleanup. Click on Browse... and copy and paste the following path:
    %LOCALAPPDATA%\think-cell\cleanup
    into the address bar and press [ENTER].
  4. Choose setup_think-cell_xxxxx.msi > Open > OK
  5. The previous think-cell version will be removed and the latest version installed > Finish

Solution 2

In this case, problems in the Windows Registry prevent the uninstallation. Such general uninstall problems can usually be resolved by following Microsoft's instructions, Fix problems that block programs from being installed or removed.
