Hi Yolanda_G,
Acer BYOC Apps can be uninstalled on Windows successfully. Only if you uninstall [AOP Framework] with any of abApps[Acer Portal/abFiles/abMusic/abPhoto/abDocs] installed, the message "Acer BYOC Components are missing from your system. Please reinstall abApp." will be prompted when you open abApps
So if there is still any abApp you want to preserve, I suggest you can reinstall another abApp again and then uninstall it without uninstalling [AOP Framework]. That is, you need to install [AOP Framework].
Hope it will help you!
