Question:

Flexnet Error -63 (LM_NOTLICDMIN) in license checkout. Not a documented *possible* return code.

Answer:

This error can be seen only in specific conditions:

- Performing Server reread from a non admin console/account and when server was started with a restrictive privilege for server reread. (-x Lmreread)
- Performing client removal (lmremove) from a non admin console/account, when server was started with a restrictive privilege for lmremove. (-x lmremove)
- Trying to shutdown the server from a non admin console/account, if server was with a restrictive privilege for server shutdown. (-x lmdown)
- If server was started with “-2 -p” and presumably “-local”, then this error will be seen by clients, if they are not a part of “lmadmin” group.

Here lmadmin group means, a Unix group called “lmadmin”
Solution: Create a UNIX group called ‘lmadmin’ and add particular user to that group.

For windows, if the operation was not initiated with LOCALSYSTEM privilege.
Solution: Try running the operation with the reference of attached batch file. Rename it to “.bat extension”.

ALSO

This error will be seen, if a particular user doesn’t have enough privilege to query the windows registry details. While performing the checkout operation, the client application queries the registry for “SOFWARE\\FLEXlm License Manager”, to get the VENDOR_LICENSE_FILE details (as well as for other operations). 

When client tries to open a handle with specific query key (RegOpenKeyEx), and in case the operation fails - then for specific error of “ERROR_ACCESS_DENIED” (returned by windows), FNP sets this error i.e. (-63, 403).
