This problem occurs when more than one App Store account is used to install software on a single machine.
I chose to add the following apps as a Pivotal Labs account (all other software was installed with my personal account):
- Wunderlist
- Evernote
- Mint QuickView
- Composure
- Simplenote
- 123DMake
- Sketchbook Express
- Adobe Revel
This list was chosent by clicking on the Great Free Apps link on the App Store.
One user says to delete the app and reinstall it.
