You can override the User Environment Manager configuration share Group Policy setting with the -FlexConfig argument.
"Flex+ Helpdesk Support Tool.exe" -FlexConfig <path>
Replace <path> with the path to the User Environment Manager configuration share without using General in the pathname. This is the path for the Immidio Flex+ Helpdesk Support Tool.xml configuration file.
To explicitly specify the location of the Helpdesk Support Tool configuration file, use the -ConfigFile argument:
"Flex+ Helpdesk Support Tool.exe" -ConfigFile <configFile>
For <configFile>, enter the path to the Helpdesk Support Tool configuration file.
