Well, good news!!

I rebooted the server just to be sure the bootstrap.dll issue wasn't just a fluke, then I ran the SQL installation repair utility, and it ran successfully and completed with a list indicating that all features were complete and correctly installed.  FINALLY.

Thank you for your help.  You got me there.

Hello,

Go to Control Panel -> Programs and Features and uninstall SQL Server Setup Support Files.

Disable any security software. What security software you have installed on that server?

Copy the media to a local folder, unzip the ISO file into that folder, and run SQL Server setup program from that folder using “Run as Administrator” option.

Hope this helps.

Sadly, I have done all these things.  I should probably add more background ad it may be helpful..  I downloaded and extracted the installation files.  I copied them to a folder on my new windows server 2012 machine and began the install.  About half way through the install it occurred to me that I wanted to install the software on my D drive rather than my C drive.  I cancelled the installation.  When it finished, I uninstalled the items that had just been installed, and rebooted my server.  When I reinstalled, I got the error.  Next I uninstalled the partial install again and this time loaded all the windows updates and rebooted to finish.  I tried reinstalling again with the same error.  I did a little research, and it looks like the sqlconf.dll is actually missing and as a result cannot be registered. 

Thanks,

Bill

Is there a way I can attach some screenshots here?  I'm a little annoyed Microsoft wanted me to open a $500 service ticket to look at this problem with new server and software...

Hi WWWIII,

In this scenario, to troubleshoot the sqlconf.dll missing error, you could download and register the dll on your computer referring the following steps, then check if the error persists.
(1)Download the ‘sqlconf.dll’ on your desktop.
(2)Copy the file to the root of your application directory and try running the program.
(3)If the step2 doesn’t work. Copy the file to the below system directory (according to your windows version and bits) and try again.
C:\Windows\System32 (Windows2012r2)
For more information of sqlconf.dll error, please refer to the link.

Hello,

Based on the fact an initial installation was cancelled half way, I suggest you to manually uninstall SQL Server using the following procedure and then try to reinstall again.

1. Uninstall all SQL Server 2014 components you can using Control Panel -> Programs and Features

2. Backup the registry.

3. Delete the following keys in regedit:

--HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server

--HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer

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

5. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and delete all the keys referencing SQL Server.

6. Rename all the SQL Server folders in the computer like

C:\Program Files\Microsoft SQL Server and subfolders.

Hope this helps.

OK

That helped.  I was able to complete the installation, but several items failed.  Twice I got the error - Unable to open registry key SOFTWARE\MICROSOFT\MICROSOFT SQL SERVER\120\BOOTSTRAP;Registry may be corrupted.

When the installation finished, 3 items failed - Management Tools Complete, Management Tools Basic, and Data Quality Client.  It said resolve the error, uninstall the failed items and reinstall the failed items. 

I looked in the registry and did not see any reference to Bootstrap in the location noted in the instructions.  Maybe it needs to be registered manually.  I also don't know how to uninstall and reinstall features.  Just run the install they way I did and follow the instructions?

I have attached a link to my old screenshots and the installation log file in case they are helpful.  Also, if I have to register the bootstrap .dll manually, what is the exact name of the file? I do not see a bootstrap.dll included with the installation files.  There is however a file named SQLSETUPBOOTSTRAPPER.DLL.

Thank you,

Bill

FYI - I just ran Microsoft System File Checker and there were no errors.

Hello,

Please read the steps outlined on the following article to add features to your existing instance:

https://msdn.microsoft.com/en-us/library/cc281940(v=sql.120).aspx

Make sure the issue you are now facing is not related with registry permissions:

Add you and the service account with Full permissions.

Hope this helps.
