How to move your Single User Global Mapper® license in a few easy steps

The day has come, you received a computer upgrade at work or you finally splurged on a new laptop. The excitement and joy of finally having a faster computer with better graphics and a new operating system can quickly be diminished by the laborious task of transferring files and software to the new machine. This blog aims to alleviate some of that headache by walking you through Global Mapper’s single-user license transfer workflow.

The first thing to do is to check the version number of your installation of Global Mapper. If you have version 20 or 21 you will be able to download the installation files directly from the Blue Marble website to your new machine. If you have version 19 or older you will need to move the installation files manually to the new computer. You’ll also want to ensure your Maintenance and Support (M&S) is still active. If you have questions or concerns about moving your license or the status of your M&S, please contact before moving your license.

Once you have checked your version of Global Mapper, navigate to the Help menu at the top of the screen, click “License Manager”, and the window below will open:

Blue Marble License Manager

Select “Release” next to the license you would like to remove. A prompt will appear to confirm that you want to move forward. Click the “Yes” button. After the removal process is complete, you should receive a message containing the removal code for your license. This code will also be copied to your computer’s clipboard. To complete the removal, send the removal code to for confirmation that your license is no longer active. After the Blue Marble licensing team verifies this information, you will be able to move your license to the new machine.

It is possible that you may not receive a prompt upon removal, but do not worry, you can access it from the C: drive. On most computers, the file can be found in the following folder location: C:\ProgramData\GlobalMapper\GlobalMapper[your version number]. The ProgramData folder is hidden by default in Windows. If you can’t navigate to that directory,  you can view hidden files and folders with the instructions below.

Navigate to the search bar next to the Windows “Start” button and type “hidden files”. This will bring you to the “For Developers” prompt.

Under the heading “File Explorer”, click the “Show settings” next to “Change settings” to show hidden and system”. The Folder Options window will open, review the options and select “Show hidden files, folders, and drives”, then click the OK button. Please note these instructions are for Windows 10, for instructions on how to access “Hidden Files” in other versions of Windows please visit the Microsoft support page.
