Error message when starting Excel or opening a think-cell datasheet: "CModuleFindChunk failed …"


On March 8, 2016, Microsoft released updates for Office 2013 and Office 2016 causing a think-cell error message as soon as you start Excel or insert a think-cell chart in PowerPoint. The error message mentions "CModuleFindChunk failed: EXCEL.EXE 15.0.4805.1001" for Office 2013 or "CModuleFindChunk failed: EXCEL.EXE 16.0.4351.1001" for Office 2016.

Another update for Office 2013 released on April 12, 2016, causes the same message for a slightly different Excel version number, "CModuleFindChunk failed: EXCEL.EXE 15.0.4815.1001".


The problem is fixed by think-cell 7 (build 24164). Please download the current think-cell version from our download web page.

If you cannot install the current think-cell version right now, uninstalling the respective Excel updates may serve as a temporary workaround.
