Installing NetBackup 7.5 client on to a 64-bit Windows server running postgreSQL fails.


When attempting to install the NetBackup 7.5 client on to a 64-bit Windows server running postgreSQL, a popup error is displayed:  "PostgreSQL is already installed on this machine.  Uninstall the existing PostgreSQL and retry this setup."

Error Message

From the NetBackup install log:

02-21-2012,14:08:37 : ERROR: PostgreSQL is already installed on this machine. Uninstall the existing PostgreSQL and retry this setup. 




The PostgreSQL validation check should not be active in the client installers. There was a bug where the check existed in the NetBackup 7.5 x64 client package.

The check is executed during server installations, and that is by design, it is to prevent installation of 7.5 servers in cases where PostgreSQL already exists.  In case the above error is received, make sure a client package is being installed, and not a server package.



This issue is resolved in version and above.  An upgrade to is recommended after applying the following engineering binary (EEB) to complete the initial 7.5 install:

Symantec Bug ID: ET2696992

Version:  NetBackup_7.5

Installation Location:  Installation Media

Installation Instructions: 

Replace the GA version of "Symantec NetBackup Client.msi" file in <MEDIA_ROOT>\PC_Clnt\x64 with the version provided in this EEB. That will disable the PostgreSQL check in the client installers.

Re-run the installation.

Note: If you are trying to install NetBackup Media Server you would need to first install the client binaries. Once the client binaries are installed then proceed with the installation of the server binaries. If you directly try to install the NetBackup Media Server binaries the installation will still fail.

So the steps would be as follows:

1. Replace the GA version of "Symantec NetBackup Client.msi" file in <MEDIA_ROOT>\PC_Clnt\x64 with the version provided in TECH182539
2. Install Netbackup 7.5 client
3. Install Netbackup 7.5 Media Server on top of the client.
