I downloaded SQL Server 2012 and installed Evaluation with full option but I can't find SQL Server Agent.

Should I download it separately?

What edition you installed? Express or some other?

Did you check agent component in the list while running the wizard

Hello - It is quite likely that you installed SQL Server 2012 Express edition in which case SQL Server Agent does not get installed. SQL Server Agent is not a part of SQL Server 2012 Express or Express edition with Advanced services.

You need to execute the following query to confirm this (See the edition information displayed by this query):

SELECT ServerProperty('Edition')

Alternative/Other Solutions:

• Put your script/ code in a script file and
• Invoke the batch file using SQLCMD utility, such as sqlcmd -i script.sql, where script.sql contains T-SQL commands that you need to call
• Call this batch file using Windows Scheduler

Hope this helps !

For Express Edition there will be NO SQL agent.

If the version is other than express. Go to SQL Configuration and start SQL agent manually

It's not Express version.

I downloaded standard version from here

I selected full options when I installed it.

Try repairing or re-installing.

You installation might have corrupted agent. From your link I can see that you have not installed express edition. 

The output of SELECT ServerProperty('Edition') is 

Enterprise Evaluation Edition (64-bit)

Hi Jeff0803,

Is the SQL Server instance installed successfully on your computer?  Please repair the SQL Server instance as other post and then show the screenshot of SQL Server Services node in SQL Server Configuration Manager.

Thanks,
Lydia Zhang

Jeff,

Before repairing to confirm whether installation was correct and you selected required features can you shares summary.txt file Below link will help you locate it

View and read setup log files

Hello

Open SQL Server Configuration Manager and see if SQL Server Agent is present.

If it is try and start the Service; if it isn't then you will need to reinstall SQL Server.

I can't find even SQL Server Configuration.

It seems that I should uninstall and re-install.

I don't know what's wrong.Can anybody give me any advice?

Your SQl Server installation passed with NO FAILURES this means SQl server agent must be installed and since you installed evaluation edition it has to be there.

Can you once more login into SSMS and see if you can find SQL Server agent , can you also check in SSCM and services.msc if you cannot fid it it seems like bug, but I have hunch that you are doing something wrong I have not seen scenario where you install SQl Server successfully and agent does not appear

I could find SQL Server Agent on the left window of the SSMS.

however I couldn't find it in the Apps.

Is this normal?
