The locations to be searched by ARM license-managed software are stored in the ARMLMD_LICENSE_FILE environment variable. These locations are always searched before any locations specified in LM_LICENSE_FILE, before the generic FLEXlm environment variable, and before the default location assumed by ARM software.

Under Windows it is possible, but not necessary, to store a license file location in the registry at HKEY_LOCAL_MACHINE\Software\FLEXlm License Manager\ARMLMD_LICENSE_FILE. If this registry entry exists, the location it holds is searched after any locations specified in the ARMLMD_LICENSE_FILE environment variable and before any locations specified in LM_LICENSE_FILE environment variable.
