Best I can give you is what is documented for TestComplete:
New versions of Chrome are released frequently. If the browser’s auto-update feature is enabled, it can automatically upgrade Chrome to a version that is not yet supported by TestComplete.
To avoid this, we recommended that you disable the browser’s auto-update feature on the test machine and install the latest Chrome version that is supported by your version of TestComplete manually.
To disable the auto-update feature, do any of the following:
-
Use the Google Update ADM template as described on the Google Update for Enterprise web page and set the Administrative Templates | Google | Google Update | Applications | Google Chrome | Update policy override property to "Manual updates only" or to "Updates disabled".
-
Locate or create the HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Update\UpdateDefault
registry value (REG_DWORD) and set it to "0".
-
Remove or rename the <Program Files>\Google\Update
folder.
To learn which Chrome versions are supported by TestComplete, go to the Google Chrome Patches page.
