Hi GEORGE ,
This might be because of the file extension “.tax2017” was mapped with the AxCrypt app. As you know AxCrypt can open only with the “.axx” files. So please change the default application for the type .tax2017 from AxCrypt to some other application.
What’s happening when you are opening the encrypted file?
Actually AxCrypt decrypt the .axx file and create a temporary file in the AxCrypt local folder. So the temporarily file will be opened with the corresponding application.
Here .tax2017 file extension also mapped with the AxCrypt app. So again AxCrypt app trying to open the temporarily decrypted file, that means AxCrypt is trying to open the .tax2017 file. AxCrypt supports only .axx file. That’s why you are getting the error message.
So change the default app for the file extension .tax2017. You can change the default app for the extension by using the following ways,
