Hi, already submit the same question under old plesk version, but seem no response. So I'll try my luck here.

When i try to tick the SSL support and click ok button, this error occur.

Error: Unable to update hosting preferences: Unable to reconfigure Web server: websrvmng failed: The file exists. (Error code 80) at GetTempFileName in E:\Program Files\SWsoft\Plesk\admin\db\

Here the details from event viewer:
