Error exceeding the number of floating licenses

Error exceeding the number of seats in the floating license, returned when setting up TerrSet on a client machine.

This may be due to semaphore files not not being deleted on the server. 

Each time a client machine opens TerrSet it writes a semaphore file to the License folder to indicate to the license that there is a user occupying one of the licenses. Once the user closes TerrSet the semaphore file is usually deleted, allowing another user to open TerrSet. When a client machine does not have ‘delete’ privileges to the License folder on the server, this semaphore file is not deleted when TerrSet is closed.

To check to see if this is the issue, follow these steps:

1. Make sure that all instances of TerrSet are closed on the server and client machines.

2. Log in to your server machine and navigate to the TerrSet License folder. 

3. Look for the semaphore files. They should look like “”.

4. Delete all of these semaphore files from your License folder, this will free up licenses for your client machines.

5. If possible, give delete privileges to the client machines to this folder.

    I have this problem, but Idrisi Selva 17. I have a server license for 15 computers.

    And the foregoing is not resolved, I still appears in error "you have exceeded the number of seats in this floating licence"

    On server machine, if the Idrisi Selva works, but on client machines not working, although run as administrator.

    Please help.

    I have the same error for TerrSet 16 floating licenses since 2016, l asked for help every year and I have tried all the methods on this website and from idrisi help service. In my lab. I have 16 client computers (window 7 os) and the server computer (window 7 os), the installation and TerrSet running on each client computer is ok when I checked one by one. When we have class, more than 10 client computers try to run TerrSet, only the first 7 client computers are running ok, the other client computers are getting error message of "Exceeding the number of floating licenses" . If I asked the students using the first 7 client computers to quit the TerrSet program, other client computers with "Exceeding the number of floating licenses" error will start running TerrSet without the error. I have submitted the same problem 3 times in 2016, 2017 and 2018. Any new suggestion this year?

    I followed the suggestion of IDRISI help to install the latest 18.31 TerrSet on the the Window 7 server after I deactivated the server lab kit license. The installation and activation server license went well but the clients still have the same warning message of   "Exceeding the number of floating licenses" . The only different is this time I only turned on 4 client computers in our computer room. I see two and in my server license folder. Any suggestion or help? By the way I have 16 licenses.
