We want to inform you about an issue where the Sage 50 application may not open due to a recent BitDefender update.

If you encounter this issue, please note that antivirus programs such as Acronis and BitDefender may cause this. Try temporarily disabling your antivirus software or temporarily removing it from your machine(s). If assistance is needed, please work with your IT. If that resolves the issue, follow Files to allow through firewall and antivirus to add exceptions for Sage 50 into your antivirus.
