Question

We are facing below error after Microsoft's October patches applied on the server.

We have set Run64BitRunTime to false and DelayValidation to True and changed path of the excel folder. Still facing below issue.

Workaround from below link resolved this issue in local machines. But In UAT server, it is not working as expected. And the reason could be below highlighted info from the link. Any suggestion on how to implement this bold highlighted? https://www.microsoft.com/en-us/download/details.aspx?id=13255

To transfer data between supported file formats and a database repository, such as SQL Server. For example, to transfer data from an Excel workbook into SQL Server using the SQL Server Import and Export Wizard or SQL Server Integration Services (provided the SSIS jobs run in the context of a logged-on user with a valid HKEY_CURRENT_USER registry hive).

The reason for this is few security patches released by Microsoft this month. To be precise they are KB4041693 & KB4041687.

It started working for me when I removed these patches. but this is not recommended solution.
