[Samsung Galaxy Watch] MacLaughlin:
So I followed your tutorial (the long way) to install the missing BP widget. Sadly I do ran into some problems when signing the BP package.

The Fit2installer states:

[Fatal Error] :1:1: Premature end of file.

Loaded in 'C:\Users\Lthal\Downloads\Fit2Installer\tizen\profiles.xml'.

Invalid file or password: ..\..\..\..\..\cert\author.p12

Any idea @Dante63 ?

Second run was a bit different with Fit2installer stating:

Loaded in 'C:\Users\Lthal\Downloads\Fit2Installer\tizen\profiles.xml'.

Security profiles have a specified profile. Will be overwritten.

author path: C:\Users\Lthal\Downloads\Fit2Installer\tizen\tizen-studio\tools\ide\bin\..\..\..\..\..\cert\author.p12

author password: **********

distributor1 path: C:\Users\Lthal\Downloads\Fit2Installer\tizen\tizen-studio\tools\ide\bin\..\..\..\..\..\cert\distributor.p12

distributor1 password: **********

Wrote to 'C:\Users\Lthal\Downloads\Fit2Installer\tizen\profiles.xml'.

Succeed to add 'MyProfile' profile.

If want to sign by this, add the file of security profiles in CLI configuration

like 'tizen cli-config "profiles.path=C:\Users\Lthal\Downloads\Fit2Installer\tizen\profiles.xml"'.

Author certficate: C:\Users\Lthal\Downloads\Fit2Installer\tizen\tizen-studio\tools\ide\bin\..\..\..\..\..\cert\author.p12

Distributor1 certificate : C:\Users\Lthal\Downloads\Fit2Installer\tizen\tizen-studio\tools\ide\bin\..\..\..\..\..\cert\distributor.p12

Package( C:\Users\Lthal\Downloads\Fit2Installer\install_me\SBP.tpk ) is created successfully.

But still, the created apk isn't installing on the watch.
