Seadrive Installation on Windows 10 Pro : "Setup failed" -- Error code 0X80070666

The execution of the Setup-exe File ends with “Setup failed”.
Error code 0X80070666 tells me that another version of the product was already installed. But the previous version of SeaDrive had be uninstalled after the trial to update failed as well. I even cleaned the WindowsRegistry from all entries containing Seadrive or Seafile.

The initial notes in the Logfile, pointing ta a possible problem were:
[2E1C:25B4][2020-01-02T13:35:27]e000: Error 0x80070002: Failed to read cache path from registry for bundle: {8fa83b6e-e530-4238-b368-580d261342ec}
[2E1C:25B4][2020-01-02T13:35:27]e000: Error 0x80070002: Failed to initialize package from related bundle id: {8fa83b6e-e530-4238-b368-580d261342ec}
[2E1C:25B4][2020-01-02T13:35:27]i052: Condition ‘DokanUninstallString OR nodriver’ evaluates to false
But the installation continues after that. Many lines talking about Dokan_64 follow. The setup end with the logfile entry:
“[33D8:2F74][2020-01-02T13:35:32]i372: Session end, registration key: SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall{f59adac7-c537-4e77-8030-3f04aa41760b}, resume: None, restart: None, disable resume: No

[2E1C:25B4][2020-01-02T13:35:33]i399: Apply complete, result: 0x80070666, restart: None, ba requested restart: No”

The only point, where I find Dokan in the Registry is cotained in “Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\AppCompatCache”

I then tried to install the latest version of Dokan and after this didn’t help too much, I installed Dokan ver. Also to no avail.
But now the error description is different. SeaDrive doesn’t complain about an older version already installed but has other complaints. Seadrive 1.0.10 Setup opens a little window telling “The error code is 2753”
The logfile mentions several times : Error 0x80070002 and Error 0x80070643 "
