The LsPush data file that is created after running the LsPush executable is actually compressed, which makes it unreadable, of course. The LsPush file that is created is meant to be imported into the Program Files (x86)\Lansweeper\Service\import folder on your Lansweeper installation. Lansweeper will then be able to read and import the file directly into your Lansweeper database. The file is successfully imported when it disappears out of the import folder.
Afterwards, you will be able to see the Windows asset in your Lansweeper web console. More information on how to individually scan Windows computers with the LsPush scanning agent can be found in
this knowledge base article.
