No thumbnail appears for flv files.
flv is included in the list of filetypes; I tried to deactivate reactivate Icaros; also to deactivate reactivate thumbnailing inside Icaros.
Then what? Thanks.

Choose to clear the Windows Thumbnail Cache from within the Tools section of the Icaros GUI.
Then reboot your system.

I tried to open 'Tools' but it is greyed out, wouldn't open.

I've cleared Windows Thumbnail Cache via Disk Cleanup, didn't help.

Can't run your file, nor open [HKEY_CLASSES_ROOT\.flv\ShellEx\ (attachments)

On the Help TAB, choose to [Remove ALL] and start with a newly acquired set of files from me (overwrite your existing files).
By using [Remove ALL], it will correct your issue.
The newly released file set (version 20.0.6) has several improvements that require a fresh start to get implemented.

Just no success :-(

Also, Tools and About are still greyed out.
