If you get an error message “File Encryption for .NET and Mono has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.” the most likely cause is a software called “Lavasoft Web Companion”. This is not compatible with modern versions of Windows, and it modifies the way the network is accessed in a way that causes AxCrypt and other programs to crash.
Check if you have Lavasoft Web Companion installed, and uninstall it if this is the case. If you’re still having the same problem or do not have the Lavasoft software installed, please follow the instructions and file a full error report.
