"With Carnyx coming to Tranquility it will no longer be possible to launch EVE Online using the exefile.exe file from EVE/bin/ folder. If you are using this method due to the issue with your launcher where 'PLAY' button remains gray after downloading an update, please pay close attention to the information provided in this article."
Two-factor authentication fully in place? Yay! But less than two hours later, CCP published a retraction.
"If you have previously been using the Repair Tool to update your EVE Online client, attempting to use it to update your client after the Carnyx release may fail.
"If this is the case, you will be required to use the launcher to update your client. If you are unable to use the launcher due to an error, please try reinstalling the launcher using the instructions in this support article.
"If you continue to experience issues with attempting to update your EVE Online client, please contact Customer Support and file a ticket under Technical Support -> Installation and Patching.
"Please note that contrary to the earlier news article, launching the EVE Online client using exefile.exe will continue to work after the deployment of the Carnyx release."
Fortunately I didn't finish the original post on the topic on how CCP had finally fully implemented two-factor authentication and how many players would shout from the mountaintops that using the launcher is evil. I guess that's a post for a future date.
