I tested parallel installation on win11 of
- gpg4win-5.0.2-beta2
- vsd-4.0.0-beta1203
The GpgOL used then was the vsd version/keyring (probably the last one installed).
Uninstalling vsd resulted in no GpgOL addin.
Maybe a setting could be added to GpgOL to select the version to be used, if multiple installations are detected?
Otherwise the installer probably should make the user aware, that gpgol will be "overwritten".
Note: Might also apply to gpgol-web.
