Hello Ayman,
Please avoid sending the same query in different mediums. You may get duplicate response.
There is no problem to open the encrypted file with a different operating system and version.(windows 7,8, windows 10).
As per logs, you have changed the AxCrypt password successfully today.
I think you perhaps are not careful enough when you type the password – or you are not aware that upper and lower case characters are different, and spaces and accents are significant when typing the password.
Are you getting any exceptions or error message while open the encrypted file? If yes, what type of exception or error message you are getting? Please share the details of that exception or error message. We are investigating the problem and solve the problem as soon as possible.
Please ensure you are typing the file password correctly or not? Please check again.
If the above doesn’t help, please provide detailed information about the issue and screenshot.also write a email to support@axcrypt.net.
