In most cases where SSSP4.0 display is unable to install our WGT package, we simply need to reset the security profile settings. Probably you are using consumer TV security profile, instead of B2B profile.

2. Using same window, click Add to add new profile.

4. Generate the certificate

5. Click on Apply. Click OK

Now, you need to change application ID again (because it is sticked to the profile)

1. Open config.xml

2. Go to Tizen Tab

3. Click Generate button

4. Ctrl + S

5. Build new WGT.
