Discovery network scans fail after reinstalling VSA


After re-installing VSA on Kaseya server, network scans in Discovery module stop working.

This error is logged in Agent Procedure log of probe agent: -



A defect has been documented in the VSA installer causing it to delete this folder - C:\Kaseya\WebPages\ManagedFiles\vsahiddenfiles\LanWatch\nmap-6.00

The problem will only occur if: -

  • "Reinstall VSA 'Version installed' and install addons" is selected on VSA Server Upgrade Options page
  • Discovery module is NOT selected from addon module list





The underlying issue will be addressed in a future release.

To correct the problem on a server which has already been affected: -

1) run the installer again

2) select "install addons only" from Upgrade Options dialogue

3) select Discovery from addon module list


Please note - it is NOT required to reinstall VSA when installing patches. The "install addons only" option should be selected from the upgrade options, and "Kaseya Patch Process" selected from the addon list.

Kaseya VSA (Discovery module)
