Why it is necessary to uninstall all the 64-bit DB2 clients before installing Toad for Data Analy -
Description
Is it necessary to uninstall all the 64-bit DB2 clients before installing Toad for Data Analysts?
When installing Toad Data Point, the error is given and it cannot be installed:"The Toad for DB2 installer has detected an existing 64-bit DB2 environment on your computer. This installation of Toad for DB2 includes a 32-bit DB2 client. However, DB2 does not allow both 32-bit and 64-bit DB2 environments to exist on the same computer."
-
Cause
DB2 does not allow both a 32bit and a 64bit DB2 environment to exist on the same computer.
-
Resolution
In newer versions of Toad, there is a version of the installer that is available that includes a DB2 64-bit client instead of a 32 bit client for environment with existing 64bit setups. Please download and install this version if there is already a 64bit client on the system.

"Toad Data Point 3.2 <>Edition Installer (for 64-bit IBM Clients ONLY)". With this installer it is not necessary to uninstall existing 64bit clients.
Note: If you have a 32bit DB2 client already on the computer and you try to run the Toad installer that includes a 64bit client, it will error out.

Additional Information
If you try to install TDA on a box with an existing DB2 client you could get the following error: "An error occurred while creating the instance "TAEVAL27". The return code is '4294965378'. Create the instance manually using the command 'db2icrt'." In older versions of Toad for Data Analysts, the 64bit client may need to be removed. The Toad installer came with a 32bit client and since it is not possible to have both a DB2 32-bit and DB2 64-bit client on the same machine, any 64 bit DB2 clients will need to be removed before installing Toad for Data Analysts. But newer versions of Toad provides a version of the installer that includes a 64bit client instead. This can be used, instead of uninstalling the existing 64bit client.
