Update to the 64-bit version of our Windows app

A 64-bit version of the Light Blue app for Windows has been available for a while now, and it gives you a better experience than using the 32-bit version of our app:

• 64-bit apps are able to make better use of modern computers and operating systems.
• Whenever someone has reported an unexplained crash or other strange problem with Light Blue on Windows, updating to the 64-bit version fixed the problem.

The only reason why you might not want to switch to using the 64-bit version of our Windows app is if you’re using a 32-bit version of Windows, but that’s very rare among our subscribers.

How can I tell which version of Light Blue I’m using?

To check which version of Light Blue you’re using on a PC:

1. Open the Help menu in Light Blue and select “About Light Blue”.
2. If you’re using the 64-bit version on that PC, it will say “Light Blue 2022.x (Windows 64-bit)”.
3. If you’re using the 32-bit version on that PC, it will either say “Light Blue 2022.x (Windows 32-bit)” or just the version number, e.g. “Light Blue 2021.2”.

How do I update to the 64-bit version?

To update to the 64-bit version of our Windows app:

1. Quit Light Blue if it’s running.
2. Go to the “Program Files (x86)” folder (which is where 32-bit apps live on a 64-bit version of Windows) and use the uninstaller for the version that’s in there to avoid accidentally launching a 32-bit version in the future. The uninstaller can have a name like “unins000”.
3. Restart your PC.
4. Download the 64-bit installer of Light Blue from the “Download Links” section of your account page on our website.
5. Run the installer.
6. Launch Light Blue and use the “About Light Blue” command from the Help menu to check that you’ve successfully updated to the 64-bit version.

I’m using a Mac, how do I make sure I’m using the right version of Light Blue?

macOS applications can include multiple versions of an app and the operating system will automatically run the correct version for you when you launch it, so there’s nothing that you need to do.

For example, macOS currently supports 64-bit applications that run on their own Apple Silicon processors and 64-bit applications that run on Intel processors, so the current version of Light Blue includes both.
