How do I connect to a remote Oracle 9i database from Windows 7?

I recently upgraded my laptop to Windows 7, and I am now unable to connect to a legacy Oracle 9i database with the Oracle 10g Client or the Oracle 9i Client.  The 9i client would never fully install for compatibility reasons, and the 10g client yields this error -->

ORA-03134: Connections to this server version are no longer supported.

I have been digging around this issue for a week or so to no avail, so any help would be greatly appreciated.

Unless some other expert knows some tricks I can't think of a way around this.

If you have the horsepower on the laptop you can create a virtual machine with a supported OS for 9i and connect through it.

slightwv - That's the answer I was dreading, but I will wait a few days to see if any solution surfaces. Thanks!
Not correct...

I connect to a Oracle 9i and 10b from windows 7 using the clients Oracle provide..

Then use Toad or C#..

You will NEED to run it in compatibility mode for Vista if you download the vista client.

You can do this with the help of SQL Developer tool provided by Oracle itself. It is java based and it does not have hassles of installations. In that you can do a direct connect by specifying the IP and SID and no need for TNS configuration. I think SQL Developer can solve your problem easily.

After installing the SQL Developer v2.1.1.64, I created a connection for an Oracle 9i database with Connection Type: Basic.  Everything else is correct as I have done this many times on pre-Windows7 OS's without any issue.  Any ideas?

Here is the error I receive:

Probably you have not downloaded the sql developer which comes bundled with java. You might be using the one where you have to install java. Try using the bundled one.
for example right click on sqlplus and then properties
and change the  compatibility mode  to windowsXP/2000 ......

After attempting the above solutions as well as a few others from across the web, I finally resolved this issue with the following process:

To install the Oracle 9i Client on the Windows7 system, follow these steps:
1.      Download the Oracle 9i Client or obtain it from another admin via BigFile. The zip file ( is 610MB, so it cannot be uploaded to the sharepoint site.
2.      Extract the Oracle 9i Client zip file, i.e. C:\Users\[eid]\Downloads. The location is arbitrary.
3.      Run the setup executable: [Extract Location]\92010NT_CLT\setup.exe.
4.      If prompted by Windows of compatibility issues, click "Run Program". This usually happens twice.
5.      Click [Next] on the "Welcome" page.
6.      File Locations should already be set:

Source: [Extract Location]\92010NT_CLT\stage\products.jar

Name: Oracle92
Path: C:\Oracle\ora92
7.      Click [Next] on the "File Locations" page.
8.      On the "Installation Types" page, select "Custom" and click [Next].
9.      Under the "Oracle 9i Client", select the "Oracle Enterprise Manager Products" and click [Next].
10.      !!!IMPORTANT!!!

On the "Summary" page, you must do the following steps before clicking [Install]. The included version of the psapi.dll file will not work with Windows 7, so you have to replace it with a working version.


11.      Rename the extracted psapi.dll in the temporary location. Open Windows Explorer and navigate to "C:\Users\[eid]\AppData\Local\Temp\OraInstall2010-10-14_09-25-29AM". The actual location will vary by user and date, so you may have to do some looking around. Rename the psapi.dll file to "psapi_oracle.dll".
12.      Copy a working psapi.dll file to the install directory. Navigate to "C:\Windows\System32" and copy the psapi.dll file from there to "C:\Users\[eid]\AppData\Local\Temp\OraInstall2010-10-14_09-25-29AM". The actual location will vary by user and date, so you may have to do some looking around. Now, you should be ready to continue the installation.
13.      Go back to the "Summary" page of the Oracle client installation and click [Install].
14.      The installation takes a few minutes and should deliver you to the Net Config Assistant.
16.      Once the installation completes, click the [Exit] button.
17.      Oracle Client 9i OEM installed.

NOTE: [eid] is an arbitrary enterprise ID which could be your local user name.  Also, to start the Enterprise Manager, I had to run it as an Administrator.
