How to set Test Complete 12 32-bit as default exe instead of 64-bit in Jenkins
The Jenkins plugin will always run the 64-bit version of TestComplete if it exists. To use the 32-bit version, rename the <TestComplete>\x64\Bin\TestComplete.exe file on your Jenkins node to a different name, e.g. TestComplete64.exe. Also, feel free to create an enhancement request for the Jenkins plugin.
