Error [1.5.-124] attempting to return a borrowed license early

Issue

When you tried to return a borrowed license from a client workstation, the following error message was displayed:

License Return Error - Your license cannot be returned. For more information, contact your system administrator. Note: you can still use your borrowed license until (midnight): <Date>. Error: [1.5.-124]

Solution

This error usually indicates that the client and/or license manager have changed in some way since the license was originally borrowed. There is no way to force the early return of a borrowed license. However, the following procedures will often resolve the error.

Method 1 - Wait out the borrow period

Depending on how long your license is borrowed and how urgently you need to return it to the network pool, it may be easiest to simply wait out the remainder of the borrow period when the license will be automatically returned. Network administrators might consider implementing an Options file to restrict the maximum borrow period or limit who can borrow licenses so the impact of future borrowing problems can be reduced. Refer to the following solution for details about configuring an Options file. Controlling network license access using an options file.

Method 2 - Reborrow the license and then return it

2. On the Start menu (Windows), click Run (Windows 2000/XP) or StartSearch (Windows Vista).
