I can't get the 4.7.4 lightning to install or activate in TB 45.4 45.5. Any suggestions? Thank you.

I tried which allows copying grouped in TB 45.4 45.5; tried to install files 4.7.x and tried to install the in 4.7.x from file. See the screenshots of the AOM console and error.

go to the extensions folder that is indicated in the error console in windows Explorer. Delete the folder with the guid that is listed. (string of numbers) It seems to me like he's trying to delete allows something so try and do first.
