I am trying to install N printing 17.3 . When i try to install N printing Sever , giving error "0x80070570 : The file or Directory is corrupted or unreadable'" on the screen. As I check the log then I get the error "Registry key not found. Key = 'SOFTWARE\Wow6432Node\Microsoft\DevDiv\vc\Servicing\12.0\RuntimeMinimum'" in the beginning.
The above error is also coming in N printing Server 17.1.
I am attaching log file of error. Please find the below mentioned errors in log .

Take a restore of the backup you took before you started the upgrade process then upgrade to 17.2 before upgrading to 17.3
Looking at the release notes you need to start the upgrade to 17.2 not 17.1 which may have caused your corruption also did you stop all the services once you had taken your backup before installing the software?
I think you will need to raise a support ticket and hope they have a repair utility.
