Antivirus and firewall software can potentially affect the functionality of the Splice desktop app, or even prevent it from being successfully installed. Potential effects of antivirus interference can include:
App launch failures
Sounds download failures
Sign in failures
If you suspect that antivirus software on your computer is interfering with the Splice app, try whitelisting and excluding the app from your antivirus, and then relaunch or reinstall Splice.
Here are some links on how to whitelist and exclude specific applications in some common antivirus programs:
Avast: Antivirus scan exclusions
Norton: Exclude files and folders
Windows Defender: Add an exclusion to Windows security
If adding Splice as an exclusion doesn't help, we recommend temporarily disabling your antivirus and then reattempting to launch or install the Splice app.
