Agent failed to get executable plugin PsExec.exe output

In OCSInventory.log I find this error:

EXECUTABLE PLUGIN => Searching for VBS script(s) in folder <C:\Program Files (x86)\OCS Inventory Agent\plugins>
EXECUTABLE PLUGIN => Searching for executable(s) in folder <C:\Program Files (x86)\OCS Inventory Agent\plugins>
EXECUTABLE PLUGIN => Found executable plugin <PsExec.exe>
ERROR *** EXECUTABLE PLUGIN => Failed to get executable plugin <C:\Program Files (x86)\OCS Inventory Agent\plugins\PsExec.exe> output

Could this be related to my already posted issue with PsExec account problem (see http://ask.ocsinventory-ng.org/2748/ocs-agent-service-and-deploy-account) ?

Or is something else going on here ?
