Several users have encountered a bug in the Mac App Store when upgrading from Adobe Carousel 1.0.3 to Adobe Revel 1.1. The issue is that the app fails to update and you get an error message:
To fix the issue, after seeing hash mismatch error:
- Close MAS
- Delete Adobe Carousel
- Open MAS
- Search for Adobe Revel, if not there, search for Adobe Carousel.
These steps have worked for several folks, so let me know if they don’t work for you.
