I had the same issue. I found the root cause after anabling ntfs-audit on file vstscannermaster.exe. The process helper.exe (C:\Users\admin\AppData\Roaming\Microsoft\Windows\Helper.exe) deletes vstscannermaster.exe each time when you start cubase 10. I don’t know why. Maybe it’s a virus or windows security etc…
I did it. I wrote about it in the first message.
I uninstalled Cubase , and then Installed 21.5Gb FULL distributive with unzipping before it.
Cant remember about As administrator...but Im administrator by default…
Can I found Only Cubase with small size?…only program, because installing wizard tell me that all components installed - only Cubase will be installed.
Then installing about 1Gb of 21,5Gb downloaded FULL distributive - only cubase re-installed
Got the exact same problem
been trying to reinstall … same issue , Vstscannermaster.exe disappears at start up of cubase
tried disabling firewall and antivirus … sameresult
tried in admin … same
tried compatibility mode … same
I keep on digging …
hotline was helpless
