SimHub is a popular software for sim racing that allows users to create dashboards and overlays

. While a free version exists, it is limited to a 10 Hz refresh rate for overlays. A SimHub license

(often referred to as a "Full License" or "Supporter Version") unlocks a 60 Hz refresh rate and additional features, such as automatic updates. How to Install a SimHub License File To activate your license, follow these steps within the SimHub application Open SimHub and navigate to the "Manage Licenses" "Add license" .simhublicense file on your computer. Select the file and click to complete the activation. Key Benefits of the Licensed Version 60 Hz Refresh Rate

Development Steps:

  1. Research and Planning: Understand SimHub's existing infrastructure and plan how the license feature integrates with it.
  2. Design: Create UI/UX designs for the license management interface.
  3. Development: Start building the feature, focusing first on the back-end for license validation and management, then the front-end.
  4. Testing: Perform thorough testing, including security testing.
  5. Deployment: Deploy the feature and monitor its performance and user feedback.

Part 7: Why is My License File Not a .license File?

Some users search for "simhub+license+file" and end up with a weird file named license.txt or key.txt.

What happened: If you purchased via the SimHub Shop and clicked "Copy Key to Clipboard," you copied a Base64 text string. If you pasted that into Notepad and saved it as a .txt, SimHub will not read it.

How to fix:

  1. Create a new text document.
  2. Paste your key (the long string of letters and numbers).
  3. Change the file extension from .txt to .license.
  4. WARNING: When Windows asks "Are you sure you want to change the file extension?", click Yes.
  5. Place this file into the Licenses folder.

If you are uncomfortable changing file extensions, simply ask the SimHub Discord bot for the .license file attachment instead of the text key.

Part 5: Troubleshooting Common License File Errors

Even with the correct file, things go wrong. Here are the most frequent issues users face with the "simhub+license+file" process.

Part 8: Frequently Asked Questions (FAQ)

Q: Can I use one SimHub license file on two computers at the same time? A: No. The license is per user, but for one active machine. If you race on a desktop and a laptop, you can only have SimHub Pro running on one of them at a time. You can move the license file back and forth, but you cannot run both simultaneously.

Q: I lost my email with the license file. Can I get a new one? A: Yes. If you bought via Patreon, go back to the Patreon page and download the attachment again. If via the Shop, use the "Lost License" recovery tool on the SimHub website or join the Discord and ask an admin.

Q: Does the SimHub license file work for the "SimHub Android App?" A: The Android app is separate. The Windows license unlocks the server side, allowing your phone to receive unlimited data. The Android app itself is usually free.

Q: How do I backup my SimHub license file? A: Save a copy of the .license file in a cloud drive (Google Drive, Dropbox) inside a password-protected ZIP folder. Do not share it publicly, as it is tied to your hardware.

Error 4: Windows Defender or Antivirus Deleted the File

Rare, but possible. Some aggressive antivirus software misidentifies license files as "cryptographic anomalies." The Fix: Add the %localappdata%\SimHub\Licenses folder to your antivirus exception list and re-download the file.
