Hi, I have the same problem as mentioned in this post and for which no answer was given.

I have subscribed to VPN Pro and downloaded the app from within the Opera browser, I first installed Opera GX and tried VPN Pro with the same result and even BSODs. After uninstalling Opera GX, I reinstalled Opera and its VPN Pro and got the same result. The taskbar app only serves to connect the VPN, i.e. the VPN works, but if you click on "Open VPN Pro" you get the annoying message that the Opera installation cannot be found.

Please, any ideas on how to fix this annoying error?
