Hello Ron,
Please install the AxCrypt app in your other system/device, then open the encrypted file in the system.
AxCrypt application and account is mandatory is decrypt the encrypted files. AxCrypt app encrypt file(s) with the .axx extension. AxCrypt encrypted files have their own file structure and AxCrypt app only can interpret and open those file(s). That’s the way AxCrypt was designed. Other than .axx extension files, can’t be opened by the AxCrypt app. No other application(s) can open the AxCrypt encrypted files.
Please check out our video tutorials at https://www.youtube.com/channel/UCoSoXBjq6iCG5232fHoWStA and our other documentation at https://forum.axcrypt.net/information/get-started/ to get started with AxCrypt.
I hope, your problem will get resolved. If not, please write the email to support@axcrypt.net with detailed information and a screenshot.
