2. Temporarily Disable Antivirus/Firewall: Sometimes, security software gets a bit too enthusiastic and blocks Lunacy. Briefly turn off your antivirus or firewall to see if Lunacy launches. If it does, you’ll need to add Lunacy as an exception to your security software. Don’t forget to re-enable your security features afterward!
3. Clear Lunacy’s Application Cache: Corrupted cache files can really mess with Lunacy’s ability to launch or function. These files can pile up and cause “Lunacy not opening” headaches. You’ll usually find Lunacy’s cache in your user’s AppData directory on Windows (like C:\Users\YourUsername\AppData\Local\Icons8\Lunacy\cache) or in ~/Library/Caches/com.icons8.Lunacy/ on macOS. Delete the contents of this folder (but keep the folder itself), then try launching Lunacy again. If you’re new to navigating file systems, understanding how to get started with Lunacy can be a helpful first step for basic troubleshooting.
4. Perform a Clean Reinstallation of Lunacy: If all else fails for persistent launch issues, completely uninstall Lunacy. Make sure all leftover files and folders are gone (check those AppData/Library directories). Then, download the latest installer from the official website for a fresh installation. This ensures all program files are clean and correctly configured.

How can I fix persistent Lunacy freezing issues?

Lunacy freezing, where the application becomes unresponsive and often shows a “not responding” message, is super annoying. Here’s how to tackle those hangups:

• Close Unnecessary Background Applications: Design software like Lunacy can be memory-hungry. Other programs running in the background compete for RAM and CPU, leading to Lunacy freezing. Close extra web browser tabs, video editing software, or games you aren’t actively using.
• Reduce File Complexity and Size: If you consistently experience freezing with a particular file, it might be too complex or large. Files with too many artboards, high-resolution images, intricate vector paths, or lots of effects can strain Lunacy’s rendering engine. Try simplifying the file, rasterizing complex layers, or breaking large projects into smaller parts. For tips on managing design assets efficiently, consider exploring different graphic design file formats.
• Update Your Graphics Drivers: Outdated graphics drivers are a notorious cause of freezing and poor performance in any graphics-intensive software, including Lunacy. Make sure your graphics card drivers are current by downloading the latest versions directly from NVIDIA, AMD, or Intel.
