How to find the smartbear testcomplete extension in chrome://extensions/

Hi Everyone,

We installed chrome 45 and testExecute 11.10. In Chrome://extensions/, we found the smartbear testcomplete 11.11.1064 extension. We remove this extension and want to enable smartbear testcomplete 11.10.xx. We installed testExecute 11.10 again, but we cannot find the extension in the chrome extension anymore.

Does anyone know how to get this extension again?

Regards,

Jie
