Oracle 9 Client Windows 7 64 Bit

So I need to have both the 32bit and 64bit clients for Oracle 11g coexist on the same machine. I have installed both together before, but there are many issues where applications that need to use the 32bit client seem to reference the 64bit client and vice versa.

Contains the Oracle Client Libraries. Download if you want the client libraries only Oracle Database 11 g Release 2 Grid Infrastructure ( for Microsoft Windows (x64). Download oracle 9i client for windows 7 32 bit. Oracle 9i client for windows 64 bit. Select Oracle 9i Release 2 Client for Windows 98/NT/2000/XP. Many of the enhancements in Oracle9i were seen in bits and pieces in later releases of Oracle8i. Oracle9i client software can run on any computer with Windows 95, 98, Me, NT 4.0.

I've searched for a long time on various Oracle forums and Oracle specific resources and tried various techniques for getting the ORACLE_HOME and such set so the two clients will play nicely side by side, but really nothing has worked.

Is there a legitimate best practice way to do this? Specifically I'm wondering about whether each client needs to be in its own BASE directory (say C:oracle and C:oracle32) or if they should be within the same base direct but have their own client folders.

I've used this persons guide to installing both versions for .NET developers for a few years now, works like a charm.

  • I want to install Oracle 9i on Windows 7, but compatibility issues. Right now I am using Oracle 10G and in 10G we cannot copy code from anywhere else. I am supposed to take print outs of the queries but 10G opens in command prompt like mode.
  • Our current application is written in Oracle Forms 6i and runs on an Oracle 9i database. Our long term goal is. To migrate both to 11g. The old server being used is running Windows 2003 (32 bit). The new server was ordered with Windows 2003 (64 bit) O/S. Is there any version of 9i database and 6i.

In my scenario, I need both clients because I have ESRI's ArcMap application (32 bit) and also their Server product (64 bit) on the same machine. I installed the 64 bit client with no problems a couple days ago and just got around to installing the Desktop application. Now I need the 32 bit Oracle client. The installer was failing stating it couldn't 'access the temporary location.' I am an admin on the box and that is not the problem. The problem was simply that the OracleRemExecServiceV2 service was running on the machine. I stopped the service and the 32 bit client installation proceeded.

I am happy with Windows 7 RTM x64 overall as everything in my development environment works well with it except for Oracle Client 64 Bit version. I downloaded the latest release and as soon as I begin installing it, it stops with an error saying that it will install on Windows version 6.0 (Vista) but does not support Windows version 6.1 (Windows 7). There does not seem to be an option to ignore and continue. Anybody know a workaround for this? Cheers!

Edit: Changing compatibility to Vista or any of the other options does not seem to work either. I am also running as administrator and have administrator rights.

Fix: See my comment below for a solution!

I have found a solution for anyone else having the same issue. Just run the installer from the command line as shown:

setup.exe -ignoreSysPrereqs

and you will be fine, you dont have to set compatibility mode (doing this will probably cause it to fail).

I got this off the Oracle forums, thankfully from someone who tried to do it on Windows 7RC.


Try right clicking on the executable, clicking properties, clicking the compatability tab and setting 'Run this program in compatability mode for' to Windows Vista or something earlier.

My problem was different, I was getting an error installing it on my Windows 7 64 bit Enterprise SP1. I would get OS not supported. Even when I tired the -ignoreSysPrereqs, it still found it as a prereq and failed it. So I modified the Oraclestageprereqdb_prereqsdbdb_prereq.xml and deleted the section that tried to verify the OS type as well as the service pack. Installed fine after that. Hope this helps

  • Run the application with the switch ignoresysprereqs
  • Removed the Oraprereq jar file which is checking the prereqs during the runtime.

If it's an MSI you can use the Microsoft Orca tool to tweak the version requirements.

You might fall foul of your license agreement by doing this.

I can confrim this solution it worked fine for me on a windows 7 enterprise edition and indeed don't set the compatibility mode cause it will fail, a second commandprompt will appear and the -ignoreSysPrereqs' will be lost the causing the installation to fail.


in some cases, (i dont knw exactly why), right click on the exe file, then going to the properties and then compatibility, you'll find the Compatibility mode disabled.Try using the 'Change setting for all users' some where below.
