This may be a DB2 Client OS privilege problem. Please try these steps to install a new DB2 client:
1) Run your DB2 Client installer (ensure you right-click the installer file and choose 'run as administrator' as this requires full admin rights).
2) When installer asks: ‘Enable operating system security’, please make sure to check-mark that box.
3) Also set this new DB2 client as the Default IBM DB2 Client on the machine.
4) Re-test the issue.
If you don’t have a DB2 Client installer file, here's an IBM DB2 Client software download link that we usually refer to our customers:
