Unexpected error from external database driver

[Former Member]

SAP Crystal Reports 16.

Standalone Windows 10 PC

Data saved as xls but in Office 365.

Since an update to Office yesterday, I get the error -

Logon failed - Details DAD Error Code 0xccb - Source DAO Workspace - Unexpected error from external database driver (1).

Access files work OK, but I need to use the spreadsheets.

I am seeing this too. I tracked it down to an update KB4041676; after uninstalling this update my CR worked fine. I hope someone at SAP can help or a new Microsoft Update fixes this issue.

Thank you - I will try to uninstall the update.

I am having identical problems however with different program versions as noted below. Also began after Microsoft updates on 10/10/17.

Crystal Reports 11

Office 2010

Windows 7 32 bit

I believe KB4041676 is Windows 10 related as it is not installed on my system. Hopefully a fix is on the way...

Yes, this KB4041676 is for Windows 10. I would try to narrow it down for your windows 7 machine on which update is causing the issue. I would talk to your system administrator though just in case.

I uninstalled the update KB4041676, and I could run my reports correctly.

But, the same update has automatically downloaded and prompted for a restart to finish installation. I have have uninstalled it again, I assume in it's wisdom Microsoft will continue to try to install. Assuming it is the same update as before, I will have the same problem.

I don not want to keep unistalling the update (which I assume contains stuff I need), so do any of you much cleverer users than me, know of a permament solution?

It's a standalone PC - on 24/7

Does this happen on the newer versions of Crystal? I am thinking of just biting the bullet and upgrading...

But, that solution only lasts as long as it takes Microsoft to do the update again!

How do I , a non-technical person, prevent this.

Or do I resign myself to uninstalling every day?

Uninstalling KB4041681 on Windows 7 wasn't enough to fix this error for us. We also had to uninstall KB4041678 (Windows 7).

Same issue and NEITHER of the updates (KB4041681 / KB4041678) are installed - any alternative answers / data access suggestions for excel file? TIA
