Upgrading SQL Server Standard 2012 from SP1 to SP2 fails

Hi there Experts,

To make the long story short.

I had an evaluation installation of SQL 2012 Enterprise SP1.

 I purchased an Open License version of SQL 2012 Standard SP2 Server and tried to convert
the evaluation version to retail version. After passing various checks I came across with the
following warning “The selected edition downgrade path is not valid”.

I decided to stop the conversion and upgrade first the SQL to SP2 (assuming that the warning will disappear)
After passing all checks with success and during installation of SP2 I received the attached error pushing me
to cancel the installation.

I then decided to bypass the first warring and convert to Retail Version although the SQL Evaluation Server
was running SP1.
The downgrade procedure went fine with no errors and I confirmed (via Select @@version query) that the
SQL was now converted to Standard SP1 (11.0.3128.0)
Following I tried to perform again the installation of SP2 which failed with the same attached errors.
I also tried to perform a repair setup with no luck.

Currently the SQL Server is running fine under SP1…
How could I bypass the errors and complete the upgrade to SP2??

Thank you for your help,

Did you chose the "Edition Upgrade" option during the setup?
EugeneZ ZhitomirskySQL SERVER EXPERTCommented:
not sure how did you downgrade Enterprise edition to standard (please post details)
So far the only way was to uninstall  Enterprise edition  and install Standard edition:
as I can see from above post: you must resolve the error" The User Data Directory in the registry is not valid...":

You may reinstall sql server after all: please make sure to do appropriate sql server DBs backups

About the SP errors:
please review the error details and try to fix them (looks like your registry for sql server was corrupted)

Dear experts,

 Thank you for your prompt replies.

I have followed the steps provided on this site in order to convert the Enterprise Evaluation to Standard Edition.

I would like to avoid reinstalling the SQL Server.Thus I tried to make a repair installation but the SP2 still fails to be installed.

Currently the SQL Server has successfully converted to Standard edition but is on SP1. When I try to install SP2 and although that all validation checks are passed the installation fails with the above attached screenshot.

Any Ideas??

as per this link ( SQL Server 2012 RTM Evaluation Edition _ I read "Real Enterprise downgrade"): ". As the Evaluation edition is a 180-day trial edition of Enterprise edition, there can be some issues when changing the edition to a non-Enterprise edition due to incompatible features used. "
it means you must on your own risk adjust Reg values to
address errors; 1 by 1 starting with this  " The User Data Directory in the registry is not valid...":'
check the master (system DBs, etc) location and adjust to this path:
(do registry keys backup)

see solution from:

and this one (similar):

SQL Server 2012 SP1 Installation issue
"Resolved by editing the registry value for HKLM\Software\Microsoft\Microsoft SQL Server\MSSQL11.<MyInstance>\Setup\SQLDataRoot - to update it to the current location of the system databases. (This value was still set to the original folder from the install)."
