Installing this update may cause applications based on the Microsoft JET Database Engine (Microsoft Access 2007 and older or non-Microsoft applications) to fail when creating or opening Microsoft Excel .xls files. The error message is, “Unexpected error from external database driver (1). (Microsoft JET Database Engine)".
Altium uses this for DBLib libraries, at least the Excel ones. I couldnt open any of my libraries, I got a EOIeException error. SoI couldnt place any new components. I dont know what else might have been broken, I had to go back to a restore point.
Forum with similar error.
