Dorico disappeared after installing the update

For what it’s worth: after installing the update from Dorico 3.1 to Dorico 3.1.10 on my pc (Windows 10 Pro), Dorico disappeared completely. The program folder was empty except for a folder called ‘fonts’. I had to use the Dorico Pro 3.1.10 Application Installer to restore the situation. Anybody else experienced the same problem?
