Solution

The itgenclr038 error can be shown due to various causes. The following steps might help you resolving them. In case not resolved after executing these steps please contact Invantive:

  • First close Excel completely.

  • End any EXCEL.EXE processes from the Details tab of the Windows Task Manager.

  • Then start Excel again from the Start menu without opening a document.

  • Wait for the Invantive Control ribbon to appear.

  • Ensure Windows updates have been applied by your system administrator when any message appears regarding Windows Update.

  • Click on “Connect“ in the Invantive Control ribbon.

  • Log on.

  • Then open the document you want to open.

  • When any yellow bar appears in directly below the menu in Excel first follow all steps as recommended by Microsoft to make the Excel document editable.

  • Perform your work.

In general it is recommended not to open an Excel document directly from a mail program or download. First save the document in the right location, then make it editable by ensuring no yellow bars are present and then use the document.
