Excel crashes when using add-ins based on Add-in Express


I experience Excel crashes and I have another add-in installed that is based on Add-in Express. Note that add-ins based on Add-in Express show adxloader.dll in Excel → FileOptionsAdd-Ins.

Solution in Add-in Express

A known issue causing this problem was fixed in Add-in Express version 9.2.4635.

Solution in the add-in that you are actually using

Note that Add-in Express is a technical framework aimed at add-in developers. Therefore, please ask the vendor of your add-in to update their Add-in Express version to at least 9.2.4635. If they need to discuss this change with the Add-in Express support, they may refer to bug tracking number #9291.

Contact Support

If you still experience an Excel crash although the vendor of the other add-in updated Add-in Express, please temporarily deactivate the add-in which uses Add-in Express, as explained in KB0091.

  • If the problem only occurs when the add-in using Add-In Express is activated, contact the vendor of this add-in. Usually it is most effective if you as the customer open a support case with the vendor.

  • Please contact our support team if you are still experiencing any issues with think-cell after deactivating the other add-in

    Please send us the think-cell log files. For this, open PowerPoint and go to Insertthink-cellMore More MenuRequest 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:

    • Open a new Windows Explorer window and type


      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 Vista and Windows 7:
        OrganizeFolder and search optionsViewShow hidden files and folders.
      • Windows 8, Windows 8.1 and Windows 10:
