Suddenly, after the most recent Microsoft update (day before yesterday), SSIS no longer recognizes Excel as a valid connection manager type. The SSIS packages have been working well for over a year. Here is the error message
TITLE: Microsoft Visual Studio------------------------------
The new connection manager could not be created.
------------------------------
ADDITIONAL INFORMATION:
The connection type "EXCEL, {8FD37A45-01A4-210C-6C6D-575139717076}" specified for connection manager "{F118BC96-4456-4B60-A69F-1E69A7BACCFF}" is not recognized as a valid connection manager type. This error is returned when an attempt is made to create a connection manager for an unknown connection type. Check the spelling in the connection type name.
------------------------------
I tried creating a new Excel connection manager, and that didn't work either.
I'm running SQL Server 2017 and the most current version of SSDT (just downloaded and installed as an attempt to fix this issue). The machine is 64-bit Windows 2012 R2.
I'm running Microsoft Office 365, but again, things have been running perfectly until today with SSIS accessing Excel.
My guess is that something, perhaps in yesterday's Windows update corrupted, whatever it is that SSDT needs to connect to an Excel data source, but that's only a guess.
Any possible solution? Is there something I need to reinstall? Please advise.
