Mac Laptop Advent Calendar Download Stopped Working: Help!

[Santapankitoo]

Hi,
I have an Advent Calendar on several devices but it has stopped working on my laptop ( Mac). Does anyone know what I have to do to fix this?
I tried contacting the company but got nowhere. Photo added

Are you logged in as a user with administrator permissions?

You can check your user permissions Settings > User & Groups

Ok. Will check that.

I am not an administrator

that would probably be the reason that you have an issue.

Are you able to contact any of the administrators or the computer to assist?

You can see who has administrative access in Settings > User & Groups

My husband is the administrator. He is not very helpful.

I was trying to sort it myself.

I suggest he makes you admin, so you can install it, and revert your permissions afterwards if desired.

Yes. Thanks @Dbank

Made myself an Admin and it is working now. Thank you .

Well, it was but it appears to have stopped.

Started again . Yay!

Hello again!
Similar problem with the new one.
I had changed the system to add me as an administrator but when I went in to check the little blue on/off beside my name is a paler colour than the blue next to my husband’s.
Any suggestions?
