While the process was running, I made a big mistake, I interrupted the install process.  I rebooted then tried again and I ge the same error. It bombs while trying to copy the Transct-SQL ScriptDom. I tried using the SqlDom.msi (x64). Any ideas? Registry or conf file?

Hi Rich Vallefuoco,


Could you please share the installation log to us to analysis? You can get it from %programfiles%\ Microsoft SQL Server\120\Setup Bootstrap\Log, please find the latest log and package it, then share it by Onedrive.


If you have only installed this instance on your machine, you can remove the previous installation manually, please use the following steps:


  1. Backup the registry and operate on the following keys:


--Delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server


--Find HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and delete all the sub-keys referencing SQL Server.

--Find HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and delete all the keys referencing SQL Server.


  1. Rename all the SQL Server folders in the computer like C:\Program Files\Microsoft SQL Server and subfolders.


Best Regards,
