InDesign Won't Load after purchasing app

[Mr. Met]

I'm helping a friend with indesign install. He bought his laptop to my office and we logged into his account and purchased InDesign only for $33/month or whatever the price is. Credit card went through and that InDesign has been installed. But when we click on InDesign it just spins and spins and never opens. We rebooted imac several times and logged out and back into in Adobe account and it shows that InDesign has been install but clicking an ID file just gets a spinning icon. I don't have the computer in front of me. I'm having him uninstall ID again, reboot, then install again. He's on a mac. I don't know what OS he's in but ID was working yesterday before he had to update credit card info. Any advice appreciated.

Full O/S and system details are going to be necessary.

Have him trash the prefs...

Moving this to Download and Install forum for more suggestions on the issue. As that is a better place for such issues.
