Question :

I used to use Microsoft’s SkyDrive without any problems in recent months. Recently Microsoft has changed the name of the app and the service to OneDrive, so I have ‘upgraded’ the app from the Mac AppStore, and it has run okay, but with various connection problems (maybe because I renamed the SkyDrive folder to the new OneDrive folder, so I didn’t have to move or duplicate files and pictures).

But that’s least of my worries. When I try to startup the OneDrive app now, I get an error message, indicating that I need to reinstall the OneDrive app. As this app is downloaded from the Mac AppStore, I looked up OneDrive in there, and it indicated “INSTALLED”, but there’s no option to reinstall…

How do I reinstall this app ?

Answer :

The solution is rather simple, but you might not consider it ‘obvious’ or ‘well documented’ in OSX :

– open the “Applications Folder”

– find the corrupted app you need to reinstall and drag it to the Trash

– open the “(Mac) App Store”-app, and find the app you need to reinstall

– when you’ve found it, you will see that it now indicates “INSTALL”, so just (re)install as usual

…that’s it

Enjoy !
