Microsoft recently released some security updates for Windows operating systems. There are currently three updates that I am aware of that break functionality in Core AutoCAD and its connection with Microsoft Excel. For instance, customers can expect that when running a Data Extraction and saving the results in an Excel spreadsheet, the first cell (A1) will display ‘DeleteMe’ and no other data will appear.
The three update numbers are:
- KB4041676
- KB4041691
- KB4041681
The remedy at this point in time is to simply uninstall the security updates until a more permanent solution is determined. Removal should restore full functionality of the features.
Inventor 2015-2011 also appears to be affected. Removal of the security updates will restore functionality pof placing such features as holes and threads. Another solution, to be taken at the customer’s own risk is to change the following registry key setting:
HKEY_CURRENT_USER\Software\Autodesk\Inventor\RegistryVersion XX.0\System\Preference\Part\UseExcelToReadthreadFile to 1
Windows 7, 8.1, 10 Updates | Microsoft .NET Framework 4.7
