Q. I already have a flexlm server running for another company's product. Can I piggy back on that existing service?

Q. I got a strange log file error when installing a flex license server on Windows:

(lmgrd) license manager: can't initialize:No SERVER lines in license file.

But I have a perfectly valid SERVER line in my file.

A. We tracked this down to the fact that after editing the license file (license.dat) with Notepad.exe the administrator saved the file with Unicode encoding. This prevented lmgrd.exe from reading the file though one could not see anything unusual in the display. Re-saving the file with ANSI encoding solved the problem.

Installation Troubleshooting

Directory naming conflict with daemon name

One of our customers installed flexlm (lmgrd and the artwork.exe daemon) in a directory called:


Upon testing the installation he received an error informing him that the artwork daemon was down or that another instance of artwork was running. The actual problem seemed to be the name of the directory and some locking that the daemon does.

Changing the installation directory name to c:\flexlm, or c:\flexlm\artwork_conversion, or any directory path that does not end in artwork fixes the problem.

Older lmtools.exe reports no licenses

One of our customers installed flexlm version 8.1 on his server. When he tested the available licenses with the lmtools utility he found that it reported no licenses available.

Upon further testing and investigation we discovered that he was using an older version of lmtools, 7.0 (or lmutil) which apparently had trouble communicating with lmgrd 8.1 and later. Upon using a current version of lmtools the expected number of licenses were property identified.
