HLK: Create package failed

Hi,

our PNP driver is a lowerfilter of the volume class.
I selected it via “Selection - device manager - volume”. The choosed volume is a ntfs volume on a second disk (so not the os volume).
Our driver was displayed at the bottom. “Group 1” is shown in the Group-Column.
All test (42) runs successful.

On create package I choosed the driver+symbol path, os and locale.
Then I got a error message pointing to eventlog:

Message : Could not add drivers into package due to empty driver path, locale list, target list objects or targets not being found in the writer object- The driver package must support at least one operating system.
Parameter name: operatingSystems

Any hint?

Thx
Norbert
