Hi,

Thanks for the response but this is not a long term solution. They already rolled back the update.

Will they need to upgrade to the latest version?

The Update affected not only Crystal Reports, but all the applications connecting to Excel with the same engine, see:

https://answers.microsoft.com/en-us/windows/forum/windows_7-update/kb4041681-and-microsoftodbc-excel-driver-reserved/c9a498d9-6b0f-444d-a8a0-9bc35d572f76

I expect Microsoft to fix the Update soon.

Uninstalling KB4041681 did not work for us.

The problem patch updated the Excel Jet connector from V4.00.9801.0 to 4.00.9801.1

We restored the old dll file "msexcl40.dll" to a new directory C:\Windows\SysWOW64\exceldriver\ and then updated the registry key HKLM\Software\Wow6432Node\Microsift\Jet\4.0\Engines\ExcelWin32 value from C:\Windows\SysWOW64\ to C:\Windows\SysWow64\exceldriver\

Hi there,

I have a client that is getting the same error but they are using Windows 8.1 64Bit.

Any idea what the Windows 8.1 update to uninstall is? I have searched for the updates listed but as suspected they are not available to uninstall.

Any help would be appreciated.

Many thanks

Ben

RE ADDED THIS TO SEE IF SOMEONE HAD AN ANSWER!?

We have had the same problem - have had to ask IT to un-install but this needs to be resolved for the long-term as we now have 2 machines without the latest security features

Is there any news on when a new upgrade is available from MS?

Is there a way to be notified so that we can re-activate upgrades on affected machines

Thanks

The best long term suggestion for now is to change DAO connectivity to OLE DB.

“Unexpected error from external database driver (1). (Microsoft JET Database Engine)” after applying October security updates.

Microsoft is working on a resolution and will provide an update in an upcoming release.

The fix is to Stop using the legacy DAO engine and move to ODBC or OLE DB to connect CR to your data sources.

Upgrade to current versions of Crystal Reports, CR 9 is 10+ years old.

I manage to refresh the report by left the connected Excel sheet open during refreshing the report. But the refreshing speed was too slow.
