How to Install Oracle on MS Windows 7 / Windows 2008R2


Instructions to Install Oracle on MS Windows 7 and MS Windows 2008R2.
These instructions can be used for either the Oracle Database software, or the Oracle Client software.

NOTE: Windows 2008R2 is only available for 64bit. Oracle does NOT certify the 32bit Database on a 64bit OS.
For MS Windows 2008R2, you can install the 32bit client software, but NOT the 32bit Database software.


Download the media from either of these sites:
  OTN (
  edelivery (

NOTE: The software currently says it is for MS Vista / 2008R1. This is the software you will need.

The steps for OTN are:
- Open a new browser session, go to
- On the Shortcuts menu bar (at the top), move your mouse over the Downloads option, and Click on the Database 11g option.
- Check the box for Accept License Agreement
- Scroll down the page, until you see Oracle Database 10g Release 2.
- Choose either:
- For 32bit Windows: Oracle Database 10g Release 2 ( for Microsoft Windows Vista and Windows 2008
- For 64bit Windows: Oracle Database 10g Release 2 ( for Microsoft Windows Vista x64 and Microsoft Windows Server 2008 x64

Run the installer (OUI).
Ignore the following prerequisite errors displayed by Oracle Universal Installer and complete the installation:
- Checking operating system requirements
- Checking service pack requirements
(Click on the Ignore Errors Check Box)

Another option is to run the following command from the CMD Line:
CD to the directory where the Oracle files were extracted.
Then run the command:
     setup.exe -ignoreSysPrereqs (case sensitive)
This will ignore the Pre-Requisite checks.

Or, to silently install the software, run the following command:
    setup.exe -ignoreSysprereqs -ignorePrereq -silent -responseFile ResponseFile

For Windows 7:
If you want to avoid performing an upgrade on the DB (when the patchset is applied), you can perform a Software Only installation (ie., do not create a DB at this time). Then after the patchset is applied, you can run the DBCA tool, and create a new DB.
Otherwise, if you create a DB during the installation, after applying the patchset, you will need to run the upgrade scripts (in the Readme Note for the patch).

For Windows 2008R2:
On Windows 2008R2, you MUST perform a software only installation. This is because the version is not certified on Windows 2008R2, only the version is certified. So you will need to install the software only, then apply the patchset. Afterwards, you can run the DBCA and create a new Database.

Once the installation is complete, you will need to Install the patch set.
This is patch number: 8202632.

Note: If you get the error below by installer
