Virtual drive fails to create/map if X: already exists

[hexa-jon]

Expected behaviour

Prompt to chose another letter or error if X: drive is already mapped to another location.

Actual behaviour

Installer finishes and then mapping X: silently fails, opening Nextcloud app gives no options to chose a folder or driver letter, files do not sync, app window shows blank.

Steps to reproduce

1. Map at network drive to X:
2. Install virtualdrive preview
3. Open nextcloud client window

We have changed our approach and now the virtual file system is set by syncing folder: https://help.nextcloud.com/t/help-test-our-desktop-client/
