Webex Not Working on Windows 10

I was trying to attend a Webex on my tablet which uses Windows 10 and I got "Invalid input or system error. Please try again or contact your site administrator."

Google Chromecast 2nd Gen Oops Something Went Wrong Error

I tried to setup a brand new Chromecast and I kept getting to the point where you connect it to the wifi and then on the screen the Chromecast itself keeps loading, but on the computer it says "Oops Something Went Wrong" with red text.

Excellent post that covers all the options to do this. The one that worked easiest for me was to install "Guest Additions" using the option to load it from CD in the Virtualbox, then enabling drag and drop and setting it to bidirections.

I recently created a new Ubuntu 14.04 in a virtualbox and it had a super small screen. I needed to install "guest additions"

I ran this:

But unfortunately it didn't get big right after a reboot. I ended up launching Xdiagnose from the Dash, and enabling all the options under the debug section.
