To determine if the problem is connected to permissions, try stopping the Bamboo service
(Start Menu >> Run... > services.msc)
manually starting Bamboo
(BAMBOO INSTALL/BambooConsole.bat)
and running the plan again. If the plan was successfully produced, please check the Bamboo service >> 'Properties' menu >> 'Log On' tab to see if the account configured has permission to run the file.
Please double-check that the service does not use the USERNAME or SYSADMIN variables. It must be a genuine username.
