Hello,

I am trying to test my application on the Tizen Device Test, this application was tested perfectly on the emulator, but when I deployed it on the Device, I got this error:

Installing the package failed.

Error code: SIGNATURE_INVALID
Error message: 
Command: /usr/bin/pkgcmd -i -q -t wgt -p "/opt/usr/apps/tmp/BirdPanic.wgt"
Management: Check author certificates in Preferences > Tizen SDK > Secure Profiles > Profile items.

I tried to generate another certification, but in vain….

How can I solve this problem? Thanks
