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.

FixSerCom Method

On the license server, a command prompt command can be used to resolve the issue with the Sentinel RMS License Manager.

Running Fixsercom

You must be logged into the server machine as Administrator to run the license cleaning utility, lsclean.exe.
Run a command prompt explicitly as Administrator (this is a right-click option):
Change the folder to the C:\Program Files...\Computers and Structures\Sentinel RMS [8.5 or higher] Utilities folder and enter the following command:
```
lsclean -fixsercom
```
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.

Cleaning File Method

A cleaning file is generated based on the Disk ID locking code of the client machine (on which error 75 occurs) by CSI. The cleaning file is then applied on the client machine using a command prompt.

Requesting cleaning files

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 & ID number
Contact name & email
Disk ID locking code for the Client machine (see image below)
Name and version of the product license(s) 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.

Applying cleaning files

Once we process your request, you will receive by email the following files, zipped into a single zip file "Clean File.zip":

laptop - cleaning file the laptop
laptop1 - cleaning file the laptop
lsclean.exe - license cleaning utility
Cleaning Instruction.doc - cleaning instructions Word file
(issued as needed) server - cleaning file for the server
(issued as needed) server1 - cleaning file for the server

You can apply the cleaning files by following the cleaning instructions in "Cleaning Instructions.doc". The cleaning instructions are briefly summarized below:

You must be logged into the machine as Administrator to run the license cleaning utility, lsclean.exe.
Clean the Laptop.
1. Unzip the "Clean File.zip" to a temp folder on the client machine. Copy the file into the CSiLicensing folder for the product whose license is being checked out: C:\Program Files\Computers and Structures\[PRODUCT NAME]\CSiLicensing folder on the client machine.
2. Run a command prompt explicitly as Administrator (this is a right-click option):
3. In the command prompt, change the folder to the C:\Program Files\Computers and Structures\[PRODUCT NAME]\CSiLicensing folder and type the following command:
```
lsclean laptop
```
  You will run both the laptop and laptop1 file if issued both files.
4. Review the Clean.LOG file created in the CSiLicensing folder and then try to check out the commuter license on the client machine again.
(If issued) Clean the Server.
1. Ensure that no licenses are in use, then Stop the License Manager server program.
2. Unzip the "Clean File.zip" to a directory on the server. From the command prompt (must be Run as Admin), go to this directory, then enter the following command:
```
lsclean server
```
  You will run both the server and server1 file.
3. Start the Sentinel RMS License Manager server program.
