Hi, all
My deb package can insatall on my N9.
But can not install on some user's N9? When user installing there will a dialog tip:

Installing failed

Installing abort

Retry Cancel

User's N9 Set-->Application-->Installing-->Allow the installation from the source of non-store is On

The version of User's N9 and mines is same.

Give me some help? Thx

Is it 100% the same package - check for hidden files like autosave files with ~ at the end!
