RemoteScanEnterpriseASP.exe - The name of the 
installer, keep in mind that this may be slightly different depending on
 the version of RemoteScan that you have purchased. 
/s - A flag that tells the installer to run in "silent" mode with no user interface 
server - Indicates which RemoteScan component to install. The "server" is the component to install on the local workstation. 
"install path" - This is the path to install RemoteScan to. Typically "C:\Program Files (x86)\RemoteScan Server". 
update_citrix_client
 - A 'Y' or 'N' flag indicating whether to update the Citrix ICA client.
 Only put a Y here if you are using RemoteScan with Citrix. 
start_server
 - A 'Y' or 'N' flag indicating if you would like the RemoteScan Server 
component to run after installation is complete. Normally, you will want
 to put a Y here. 
hide_program_group - A 'Y' or 'N' flag indicating whether to hide the RemoteScan program group. Normally set to 'N'. 
as_service
 - A 'Y' or 'N' flag indicating whether to install and run the 
RemoteScan Server as a service. For Terminal Services and Citrix, we 
strongly discourage running RemoteScan as a service and suggest using a 
'N' here.
update_scansnap - A 'Y' or 'N' flag indicating whether to update for Fujitsu ScanSnap. Only put a Y here if you are using RemoteScan with Fujitsu ScanSnap Manager or Fujitsu ScanSnap Home and ScanSnap Manager or Home is already installed.
Example script for installing RemoteScan Universal onto a workstation which does not use Citrix, instructs RemoteScan to not run after install, doesn't hide RemoteScan in the program group, doesn't run RemoteScan as a background service, and does utilize Fujitsu ScanSnap drivers:
RemoteScanUniversalASP.exe /s server "C:\Program Files (x86)\RemoteScan Server" N N N N Y
