Summary

When applying agent policy on Flexera One beacons, attempts to install packages that are part of the policy fail with logging like the following:

[6/26/2022 9:43:23 PM (G, 6)] {9708} Installing “InventorySettings[Common]...](1,0,0,0)”

Details

This behavior occurs because an internal installation agent property VerifyCatalogSigned is set to true, indicating that only packages which are digitally signed can be installed. This is to ensure that packages the beacon downloads from the Flexera One environment are signed. However a side effect is that packages in agent policy cannot be installed, as these packages are not signed.

A package that will fail to install due to this issue is the “InventorySettings” package. A consequence of this package not being installed as that the inventory gathering process will be unable to gather details of some specialized software applications that may be installed, such as Oracle Database, Microsoft Exchange Server, and others. This is not typically a concern, as it is unusual to have this type of software installed on Flexera One beacons.

Mitigations

The issue will not occur if the VerifyCatalogSigned preference is set to false (configured in the HKLM\SOFTWARE\Wow6432Node\ManageSoft Corp\ManageSoft\Launcher\CurrentVersion\VerifyCatalogSigned registry entry). However changing this configuration is not recommended as it means the beacon will not require details downloaded from the Flexera One environment to be signed.
