I recently had a problem where I cannot open the MasterCook Windows program or cookbooks. What can I do?
First, please follow these instructions but not the reinstallation option yet:
If that doesn't work, make sure your antivirus program isn't blocking MasterCook.
Recently other users found that the Ransomware Protection program in Windows was blocking MasterCook and causing the issue. They disabled the Ransomware Protection program and then MasterCook was functioning fine. Try the same and see if that helps.
Antivirus programs generally have an Exclusion List. If you find that your antivirus program is causing the problem, add MasterCook to your antivirus program's Exclusion List. See the documentation that comes with your antivirus program or contact their Support Department.

If you continue having an issue, it could be you have a corrupt installation. Please reinstall as explained here:
