Answer:
The default path for the company logo is C:\ProgramData\Dlubal\Global\General Data\Logo.bmp.
This path should appear automatically in the printout report header settings; see the image.
The path for the customer logo should also be visible and editable in the registry under Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\DLUBAL\AUTHORIZATION.
As an alternative, please save your company logo in the bmp format and under the name "Logo.bmp" in the directory C:\ProgramData\Dlubal\Global\General Data.
