TestExecute and Chrome

Does Chrome need the testcomplete extension to run in chrome? having difficulties getting it installed. Have tried modifying the testexecute install, reinstalling testexecute....when I check extensions for testexecute all extensions (including chrome) are checked, but it doesn't show up in top right or extensions list.

Have also tried dragging the extension file manually into the extensions page, but received an error saying I can't install extensions from that page.

Just wondering if it's required and if so what could be causing the difficulties installing it. Reason I mention it is I'm trying to run a distributed test on chrome and it can't find any objects on the page. Thought maybe had something to do with missing the extension, or possibly an issue with namemapping (although all objects are not system specific)

also let me add testcomplete is on 64x machine and testexecute is on 32
