The error 75 occurs when checking out a commuter license. Error can occur when an issue with the Sentinel RMS License Manager cannot be recovered automatically or if there is an issue with persistence files/registry on the client machine. Persistence data may also becomes corrupted when different versions of client and server are used together in a mixed environment.

Overview

There are two possible methods to resolve this error. Please try the first option before requesting a cleaning file for the second option. 

...

1. You must be logged into the server machine as Administrator to run the license cleaning utility, lsclean.exe. 
   
   

2. Run a command prompt explicitly as Administrator (this is a right-click option):

   

3. Change the folder to the C:\Program Files...\Computers and Structures\Sentinel RMS [8.5 or higher] Utilities folder and enter the following command:

   Code Block
   lsclean -fixsercom

   

4. Review the Clean.LOG file created in the Utilities folder (C:\Program Files...\Computers and Structures\Sentinel RMS [#] Utilities) and then try to check out the commuter license on the client machine again.

...

Only request a cleaning file if the Fixsercom method above did not resolve Error 75. To request a cleaning file, please email the following information to license@csiamerica.com:

• Company name Customer & ID number
• Contact name Contact & email
• Disk ID locking code for the Client machine (see image below)
• Name and version of the programproduct license(s) license you are checking out

Disk ID locking codes can be obtained by running, "as administrator", the wechoid.exe utility located in the program installation folder. When copying the locking code, ensure that only the box for Disk ID is checked. Once we receive this information, we will send you the cleaning files along with instructions how to apply them. The instructions are also provided in the following section.
