We recommend updating to the latest available version for best compatibility:
Windows 10 users: Update to version 22H2
Install Windows 10 updatesWindows 11 users: Update to version 22H2 or higher
Install Windows 11 updates
2. Check for Antivirus or Firewall Interference
Some antivirus software or firewall settings may block the Splice installer.
Try this:
Temporarily disable any third-party antivirus software (e.g., Avast, CCleaner, BitDefender).
Disable any network firewalls.
Try installing Splice again.
If it works, add Splice to your antivirus/firewall exceptions list or whitelist to prevent future issues.

3. Verify Microsoft .NET Framework Installation
Splice depends on the Microsoft .NET Framework. Make sure you have the latest version installed:
Download here: Microsoft .NET Framework
4. Try Installing in Safe Mode with Networking
Booting into Safe Mode with Networking disables third-party software and services that may interfere with installation.
If installation works in Safe Mode, the issue is likely caused by:
Antivirus software
Firewall settings
Background applications
5. If Installation Still Fails
Download the installer again from splice.com/download.
Run the installer and note any error messages or take screenshots if it fails.
Check for error or log files in these folders:
