Are you trying to access the Extension Warehouse directly from SketchUp? Have you cleared the Internet Explorer caches? In at least two other threads you’ve been given instructions on how to fix this. Have you tried following those instructions? ---

While you may use Chrome as your default browser, SketchUp only uses IE so yes, you need to clear IE’s caches, make sure it is update and follow the other instructions you were given. In IE, click on the gear icon in the upper right corner. Then Internet Options. Under the General tab find Browsing history and click on Delete… ---

I don’t exactly know why this happens, but even after clearing IE’s cache, it still throws me that error. But In several occasions, Sign in attempts three times in a row actually will get me through. I’ve given up on trying to fix that. ---

(Moving to [**Extension Warehouse**](http://forums.sketchup.com/c/extension-warehouse) category, where these kind of issues belong.) * * * I have also noticed this error recently, from within SketchUp, after never having much problems (if any,) since the EW was launched for the 2013 release. What I did to get logged in, was first click the little man icon on the lower left of the SketchUp status bar, and go thru the Google log in screen. Once the “man” icon was bold and I was logged in from SketchUp, then I went to **Window** \> **Extension Warehouse** and was logged in fine. From there I could install any extension without issues. * * * ---

We’ve finally been able to reproduce this on Windows only, and with an intern who’s University has a login shim that pops up immediately after the Google OAuth login page that makes him login to his University account as well. The lower left login/logout is his only option, so hopefully we’ll be able to fix this with a case we can reproduce in house. ---

We are having this issue on hundreds of computers now. We have found a work-around by installing the security certificate, but this shouldn’t be necessary, and we have too many computers to touch for this to be a viable solution. ---

Maybe you should find out what online bankers, sellers etc. do to establish a secure link. Once a server has a valid certificate issue by a CA ( does trimble have one?) if the client machine is set for SSL or TSL then the hand shakes that occur are almost automatic. Although IMO this all started when Trimble was trying to set up so those not ok with the terms of service would not get access. The work around is simple, open su screen and log in to Trimble ( Not the Google option ) for ware house and extension warehouse using the status bar button. Do not use old Google log in since the Trimble PWD rules are different( It requires special characters) [http://forums.sketchup.com/t/authentication-error/22793/48](http://forums.sketchup.com/t/authentication-error/22793/48) than Googles. It also helps to select the check box so login is remembered. ---

Sorry my first comment was en-excusable and did not pick that up at first read you are in an enterprise environment. The solutions can be expected to be different. MS has some extensive free tutorials on the subject, this one maybe be of interest to you since it addresses Active Directory. [03 - Understanding Active Directory - Active Directory Certificate Services CS - YouTube](https://www.youtube.com/watch?v=J8y4G0dD-hg). My background is in military grade encryption and authentication and many differences vs. what you deal with.
