The patch number is 6153263 and obviously it is only available for the Microsoft Windows 32-bit platform.
After you have downloaded the patch make sure you unzip it into a folder where there are no spaces in the path. A folder like this will work fine: c:\downloads\oracle\vista
After you have unzipped the patch you should notice a new folder called Disk1 containing a setup.exe file.
With the new setup you can install onto Vista in one of the two following ways:
Install Method 1:
In command line mode (aka DOS) go into the folder containing the new setup.exe and launch it pointing to the products.xml file of the original install, like this:
Note: if your path contains a space you must enclose the whole file location in double quotes, like this:
setup.exe FROM_LOCATION="c:\downloads\oracle\10g Tools\stage\products.xml"
Install Method 2:
- Within the Vista UI, use Explorer and navigate into the folder containing the new setup.exe
- Double-click setup.exe
- On the Specify File Locations screen, navigate to the products.xml file in the location where you unzipped the original Tools software
