    Here are the error detail traces :
    *************************
       at Wasp.Rules.Inventory.WtItemRules..ctor(WtSecurityRules rulesSecurity)
                                        |    at Wasp.Inventory.Service.InventoryService.SearchForItem(String sSearchValue, Boolean bSearchOnSN, Boolean& bMoreThanOneMatch, String& sSerialNumber, WaspError& waspError)*************************

Cause

On the service PC, the folder C:\Program Files (x86)\Wasp Technologies\InventoryControl\Services contains files with the extension .rra which indicate a patch or installation has been run to conclusion, but that process couldn't update files that were in use, and the PC was not rebooted.
 

Resolution

Reboot the PC/server where Wasp Inventory Windows Service is running.
