MATLAB: Do I receive a “File not found” error message in the license manager log file after starting the network license manager

Question

When I start my network license manager on Windows, the license manager starts, but the log file says it cannot find a file:

License server manager (lmgrd) startup failed:

(lmgrd) License server manager (lmgrd) startup failed:

(lmgrd) File not found, C:\Program

(lmgrd) Started MLM (pid 5456)

(MLM) Using options file: "Files\MATLAB\R2008a\flexlm\mlm.exe"

What does this error mean and how can I resolve it?

Answer 1

This errror occurs when the network license manager is installed in a your path that has a folder with spaces such as Program Files. When this is the case, the DAEMON line in the license file must specify the path to mlm.exe with double quotes. If you do not put quotes in the path, the license manager will be unable to find the mlm.exe file.

To resolve this issue, open the license.dat file for the license manager and locate the DAEMON line. Enclose the path to the mlm.exe in quotes. For example:

DAEMON MLM "C:\Program Files\MATLAB\R2007b\flexlm\mlm.exe"

Once updated, Stop and restart the license manager to resolve the issue.
