How to reproduce the error:
1 – I encrypted some critical spreadsheet files.
2 – When I start working I open the encrypted file in LibreOffice 126.96.36.199 (x64) and enter my Axcrypt password.
3 – Libre office makes automatic backup files and temporary files in the windows profile.
4 – The day after working in my spreadsheet. AxCrypt says either. Can’t decrypt or can’t encrypt this file for an unknown reason. I suspect the backup files which are created automatically by LibreOffice (default in every LibreOffice) have to do with Axcrypt being unable to identify or locate the file.
I will post more details as soon as I get the message again.
