Hi Samartha,
Do you have a machine where you can access TestExecute UI? If you do, you can try disabling the needed extensions in it, export the HKEY_CURRENT_USER\Software\SmartBear\TestComplete\9.0\UserData\managers\{69fb0002-d3da-41ed-909b-12bef03232b8} registry key and import it to the machines where the other installations of TestExecute reside. Otherwise, let me know which extensions you need to have disabled - I'll try to create a modified key for you. Note that you can send me a list of the extensions to be disabled through the support case you submitted.
