Fresh install, Ubuntu: "There was an error launching the application

Fresh install on Ubuntu, (Mint). Downloaded zip file from github, (I am unfamiliar with git, and it seemed simpler). Install seemed to go fine, no errors were produced. On attempts to open the install, an error dialogue pops up saying “There was an error launching the application.” It gives no codes and prompts for me to click ok.

I am going to remove it and try again tonight, perhaps using the proper github channels. Any help or suggestions is appreciated.

Sorry if this is a repost, but I haven’t seen any similar error messages on this or other forums.

Thanks.
