Closed Unassigned: Verfication of file signature failed [192]

Hi

My WPP Version: 1.3.1405.17
Server Version: 3.2.7600.262
Console Version: 3.2.7600.262

I got the following error when I try to Create a new update of a own-created MSI:

Verfication of file signature failed for file: \\(hostname)\UpdateServicesPackages\(character string)_2.cab

I tried the following:
- MSI on a network share in LAN
- MSI on a local drive C:\WSUS

Both was failed.
