The think-cell license key window pops up

think-cell requires a valid license key to run. The license key is checked on each start of Microsoft PowerPoint or Microsoft Excel. If no valid license information is found on your system or if the license key is about to expire, the think-cell license key window is displayed.

When entering think-cell's license key manually, it is saved when closing PowerPoint or Excel. Follow these steps to ensure the license key can be saved correctly:

  1. Make sure that no hanging processes prevent think-cell from writing the license key

    1. To ensure that no hidden PowerPoint or Excel processes remained stuck on your machine, disrupting normal operation, please restart your PC.

      Alternatively, close all respective processes in the Windows Task Manager.

      1. Open the Windows Task Manager and check for remaining POWERPNT.EXE or EXCEL.EXE processes.

      2. End these processes.

    2. Open PowerPoint

    3. Enter a valid license key in the think-cell license key window.

    4. Close PowerPoint

    5. Ensure in the Windows Task Manager that the POWERPNT.EXE process was terminated successfully.

  2. Check if you have sufficient permissions to write into think-cell's user profile folder

    1. Open think-cell's user profile folder:
      Press Start or the Windows key → type %appdata%\think-cellEnter

    2. Right click into the folder → NewText DocumentENTER

    3. Are you able to open, modify and save this file?

      If not, ask your internal IT to give you sufficient permissions to modify and save files in your think-cell user profile folder.

  3. If the license key window is displayed again on the next start of PowerPoint, contact our support team and send us the following files:

    • Open think-cell's user profile folder (%appdata%\think-cell) as described in point 2. Check if you have sufficient permissions... You should see the settings.xml file in this folder. Please send this file together with a screenshot of think-cell's license key window to our support team.

    • Please send us the think-cell log files. For this, open PowerPoint and go to Insertthink-cellMoreRequest Support. The log files will be automatically attached to a new email.

      If this does not work, you can find the log files as explained below:

        %LOCALAPPDATA%\think-cell

        into the address field and press Enter.

      • If you want to browse to these directories but cannot see them, they are probably set to invisible. You can change that in Windows Explorer by checking:

        • Windows 8, Windows 8.1 and Windows 10:

      • Please send all files with the extension .log contained in this folder to our support team. This may be any of the following files: POWERPNT[_log].log, EXCEL[_log].log, TCMAIL[_log].log, setup_think-cell_xxxxx[_log].log.
