Problem

When you open PowerPoint or Excel, or when you insert or edit a think-cell chart, an error message appears that mentions "CFindCodePattern failed" or "CModuleFindChunk failed." This error typically appears after an update for Microsoft Office has been installed.

think-cell error message "think-cell is not compatible with your current Office version. Request Support to find out if this problem has already been solved. think-cell will be disabled."

Solution

Download and install the latest think-cell version from our download page.

If you've joined the Microsoft 365 Insider beta program, you might have installed an Office update with which think-cell is not yet compatible. In this case, you can opt out of the Insider program.
