Cannot open file created in KeePassXC

[krautcat]

Hi there,

I have an issue with opening database created in KeePassX and upgraded to OTP secret in KeePassXC.

This is my KeePass installation directory tree:

PS C:\Program Files\KeePass Password Safe 2> tree /f

Placing dll's into directory with KeeChallenge.dll didn't help. Also placing all dlls into the directory with KeePass's exe file didn't help too.

Tried to open local file and change the slot, nothing helped.

Error message:

Unfortunately, the OTP mechanisms used by KeeChallenge and by KeePassXC are fundamentally incompatible. One requires a ride-along XML file, while the other changes the database file itself on every save. (These have different security and usability implications, and neither is strictly superior.) Check https://keepassxc.org/docs/#faq-yubikey-no-extra-file for more info.
