Update provided below!
Google has been threatening to remove NPAPI (Netscape Plugin Application Programming Interface) support for some time now and they’ve tested the waters with version 42 by disabling it. Since the VMware Client Integration Plugin requires NPAPI, administrators now have to enter their credentials manually. Terrible, I know!
Apart from having to enter your credentials by hand, you’ll also lose the ability to transfer files from your desktop to a datastore via the browser or deploy OVF templates. You can still console VM’s via your browser and with the VMware Remote Console.
If you’ve updated Chrome, it’s too late as Google does not support rolling back. IE will continue to function however. I have contacted VMware regarding this issue and will provide immediate updates.
UPDATE: Google has provided an override to enable NPAPI support. Simply enter the following in your browser:
Then click Enable.
