Please check out http://support.smartbear.com/viewarticle/42533/ for information on support for Chrome 42 and NPAPI plugin. TestComplete works with Chrome 42 with the changes outlined in the article mentioned.
Looks like a new version is available that will support Chrome 45: http://community.smartbear.com/t5/Functional-Web-Testing/Google-has-now-removed-npapi-support-from-Chrome-what-is/m-p/104863?&_ga=1.157969978.166990057.1441195869#M25569
"We’ve just released TestComplete 11.1 that supports new Chrome 45 (without NPAPI). So, you need to update your TestComplete version – click Help | Check for Updates from the TestComplete main menu."
Updating TestComplete to version 11.10 fixed the issue for me. Thanks!
