“The file name is invalid as it contains spaces.  Please rename the license file and try again”

This message is a bit misleading when trying to upload your new port license to your fabric interconnect.  It could very well be your ‘file’ that has the error, but what do you do if you get this message and your license file doesn’t contain spaces?

Put the license file in a directory path that contains no spaces.  That should clear up the issue.

ie: c:\license.lic
