Oracle 10g is successfully installed on Windows 7.

My system is win7 32-bit flagship Edition
 
Oracle 10g 2nd is installed
 
Step 1:
 
Modify the two refhost. xml files in the installation file directory in the db \ Disk1 \ stage \ prereq \ db and \ db \ Disk1 \ stage \ prereq \ db_prereqs \ db directories.
 
Right-click notepad and edit it. Find the following code snippet:
<! -- Microsoft Windows vista -->
<OPERATING_SYSTEM>
<Version value = "6.0"/>
</OPERATING_SYSTEM>
 
Add:
<! -- Microsoft Windows 7->
<OPERATING_SYSTEM>
<Version value = "6.1"/>
</OPERATING_SYSTEM>
 
 
Principle: Oracle has not released any version for windows 7 so far. During version check, it is prompted that oracle currently does not support windows OS with version 6.1. Download oracle 10g for vista and windows 2008 x86 for windows from the oracle official website supports the vista kernel. The windows 7 kernel is similar to the windows and vista kernels, after the above modification, you can bypass Oracle's check on the system version and install it normally!
 
Step 2:
 
Cancel UAC permission protection for Windows 7 by running msconfig in the Start Menu, find the "Tools" tab, select UAC related entries, click "run", and set the level to the lowest. (This step is from the internet. I don't know if it is necessary)
 
Step 3:
 
Set the compatibility mode of the folder db \ Disk1 \ install \ oui.exe by right-clicking the selected file and clicking "properties" to set the compatibility mode to Vista SP2.
 
Restart the installer and install everything as usual.
