RESOLUTION 1:
Toad supports DB2 Client versions 9.7.6 through 11.1.
Toad has been tested with the following versions of the DB2 Client: 9.7.6, 9.7.9 , 10.1.0, 10.1.2, 10.1.3, 10.5.0, 10.5.2, 10.5.3, and 11.1.0.

RESOLUTION 2:
The Windows OS upgrade has invalidated your IBM DB2 Client software. Please re-install your IBM DB2 Client.

Here's an IBM DB2 Client software download link that we usually refer to our customers:
IBM Data Server Client Packages Version 10.5 Fix Pack 3:
http://www-01.ibm.com/support/docview.wss?uid=swg24036706
Download the package noted as:

"IBM Data Server Client" (1st item) - Description: This is the all in one client package and includes all the client tools and libraries available. It includes DB2 Control Center, a graphical client tool that can be used to manage DB2 Servers. It also includes add-ins for Visual Studio.

Note: If there are any issues with the download or install of the client itself, please follow up with IBM DB2 Support for further assistance with the client.

Note: Please ensure you install it with the highest Administrator Rights (in both the local PC and your network domain). Right-Click the installer file and choose "Run as Administrator". If you do not have it or if you are unsure, please have your IT or Helpdesk people install it for you.
