If you have been provided a GAUSS license file and are still receiving a License Manager (or 491) Error, the reason you are receiving this Error is that GAUSS cannot find a valid license file.
The License Manager error, including 491-License has Expired Error, may also be caused by one of the following reasons:
- Temporary license file has expired
- License file generated on incorrect HostID number
- License file saved in wrong location
- Incorrect file extensions
Temporary license file has expired
License file generated on incorrect HostID number
Your GAUSS license is generated on the HostID of the computer on which it was installed. For instructions on how to regenerate/verify the hostid number of your computer, click here. Copy and paste the output into a License File Request.
License file saved in wrong location
Your GAUSS license file must be saved, retaining the *.lic extension, in your main GAUSSHOME folder. If the license file is saved to the Downloads folder, flash drive or other location, and doesn't get moved or copied to the GAUSSHOME folder, your license file will not work.
To resolve this issue:
- Resave the license file you were sent to your GAUSSHOME folder. OR
- Open your File Manager, Windows Explorer or Finder and drag the GAUSS license file to move it from your Downloads folder to your GAUSSHOME folder.
Incorrect file extensions
The GAUSS license file MUST end with a .lic file extension. Two of the most common reasons why GAUSS is not able to find or read a license file are that:
- File saved with a .txt file extension. The default on many Windows text editors such as Notepad/Notepad++ is 'Text Document (*.txt)'. This can cause the license file to be saved with an extra file extension, such as 'txt' if the license file is saved using File>Save As and 'Text Document (*.txt)' is selected. This will result in the license file being saved with a double extension, either .lic.txt or .lic.html.
- macOS Users/Safari. Sometimes, the Safari browser adds an extra .txt extension to some file names (not all), causing the files to open in TextEdit or to save the license file with a .txt file extension, such as 69999-01_GH18-Smith.lic.txt.
To resolve this issue:
- Save with the correct 'File Type'. What makes saving the license file particularly confusing in Windows is that the Windows File Explorer will ONLY show the first file extension, so it is difficult to know exactly how the file has been saved.
- To avoid this problem with Notepad/Notepad++, when you perform File>Save As, select the 'Save as Type' button: "All Files (*.*)" and specify the file name that was used on the file that was sent to you, such as 69999-01_GH18-Smith.lic.
- Select 'All Files' as your 'File Type' which will allow you to retain the 'lic' file extension.
For example, if we have a license file saved as temporary.lic.txt, the Windows File Explorer will show the file name as just temporary.lic like this:
However, if we look at the third column in the image above named 'Type', we see that the file type is listed as 'Text Document'. This is because, the file is really named temporary.lic.txt. We can see the real full name of the file, by right-clicking over the file in our Windows File Explorer window and selecting 'Properties' like this:
- Rename the license file. You can rename the license file by:
- Windows / Rename in Windows Explorer: -Go to your GAUSSHOME folder in Windows Explorer: c:\gauss19 -Right click the license file -Select the option that says 'Rename' -Remove the .txt file extension -Click the file to save the new name -Start up GAUSS
- macOS / Rename in Finder: -Go to your GAUSSHOME folder in Finder: /Users/YourUserName/gauss19 -Right click the license file -Select the option that says 'Rename' -Remove the .txt file extension -Click the file to save the new name -Start up GAUSS
- Use the 'copy' command from the Windows Command Prompt [macOS/Linux Terminal Window] where your file has been saved, such as your Downloads or gauss19 folder. For example:
copy mylicensefile.lic.txt mylicensefile.lic [For Linux/macOS: cp mylicensefile.lic.txt mylicensefile.lic]
- Download the license file again without opening it first. If your license file has the correct file extension, the file type column in the Windows File Explorer should report that the file is a LIC file as in this next screenshot. Some internet browsers, like Chrome will, allow you to change the browser settings so that you can specify where you want a downloaded file saved and what you would like it named.
