When I run the app from the Tizen IDE, it gives an error saying

Installing the package failed.

Error code: FATAL_ERROR
Error message:
Command: /usr/bin/pkgcmd -i -q -t wgt -p “/opt/usr/apps/tmp/Watchful.wgt”
Management: Installation or uninstallation is not working temporarily.

BTW, the emulator is up and running, even responded to the command by rearrange the app icons, but then the error above.

How so?
