Hi, I have written an ENVI batch script which works fine on a desktop which has ENVI 4.3 installed. This ENVI installation uses a floating license. I have tested the script on a desktop which has ENVI 4.6 installed and the ENVI installation connects to a license server. This desktop produces the following error when 95% of script's commands have been executed: ``The ENVI license feature was not found. Please start the ITT License Wizard to request an evaluation license. Start->All Programs->ENVI 4.6->License Wizard'' On the server, the following message was logged: 13:15:03 (idl_lmgrd) UNSUPPORTED: "envi_bathymetry" (PORT_AT_HOST_PLUS ) RMain@RMAIN-WS2 (License server system does not support this feature. (-18,327:10054 "")) Can you please guide me to find the root of the problem. At this point I am clueless and I have no idea where to start. Regards Willem
