是P4的机子吗？如是，请参考：
Oracle 8i在P4上的安装方法一: 1、将ORACLE软件拷贝到硬盘。
2、将 硬盘目录文件\stage\Components\oracle.swd.jre\1.1.7.30/1
\DataFiles\Expanded\jre\win32\bin\symcjit.dll 的文件改名为
symcjit.old
3.从\install\win32 目录下运行SETUP.exe 文件进行安装。 前提是：机器上没有装过Oracle产品。如有的话请先卸载，再将注册表中Oracle项删除。
方法二、（此方法斑竹成功安装，但较麻烦,方法的核心是加 -nojit)
.. Copy only the install directory from the CD to the hard disk ,say, e:\temp. b. Open oraparam.ini and make the following modifications (Assuming CD
drive is f:) * Change the "SOURCE=" line to use the full path to the CD instead of a
relative path. (i.e., SOURCE=f:\stage\products.jar) * Change the "JRE_LOCATION" line to use the full path to the CD instead of a
relative path. (i.e.,
JRE_LOCATION=f:\stage\Components\oracle\swd\jre\1.1.7\1\DataFiles\Expanded) * Change the "OUI_LOCATION" line to use the full path to the CD instead of a
relative path. (i.e.,
OUI_LOCATION=f:\stage\Components\oracle\swd\oui\1.6.0.9.0\1\DataFiles\Expanded * Change the "JRE_MEMORY_OPTIONS" line to add "-nojit" as the first argument.
(i.e., JRE_MEMORY_OPTIONS=-nojit -ms16m -mx32m)
^^^^^^
* Other entries should remain the same c. Launch setup.exe from the temporary location on your hard drive (i.e.
e:\temp\install\win32\setup.exe). This will use the modified
oraparam.ini and pick up the information from the CD since the absolute
locations are specified. Choose a Custom install and choose not to create a database during the
install. This way, the Database Configuration Assistant will not be launched
during installation. The Net8 Configuration Assistant will still be launched, and there is no way
to suppress it. You will need to kill the Net8 Configuration Assistant if it
hangs due to the bug. The installation still will have been successful, and
you can run the DBCA and NetCA after installation. To kill NetCA if it hangs during installation:
In the "Configuration Tools" window, highlight the "Net8 Configuration
Assistant" and click "Stop". If that does not work, look for the most recent
JRE process using the Task Manager, and kill it manually. NOTE: the OUI
itself will also have a jre process. Be sure to kill the one with the most
recent date, which should be the jre process being used for Net8CA, not the
one for OUI itself. After killing the configuration tools and continuing through the installation
to the "End of Installation" screen, you should modify the configuration tools
to use "-nojit", then call the appropriate tools from the Start Menu. Once installation is complete, each of the following files in the ORACLE_HOME
needs to be modified: assistants\dbca\dbassist.cl
assistants\dbma\dbmig.cl
assistants\ifa\ifa.cl
bin\elogin.cl
bin\owm.cl
ldap\oidamdin\oidadmin.cl
network\tools\netasst.cl
network\tools\netca.cl
owm\install\instelogin.cl
owm\install\instowm.cl Edit the contents of the above files to add "-nojit" as shown below:
Command=("C:\Program Files\Oracle\jre\1.1.7\BIN\JREW" -nojit -classpath ....
this is the only thing you need to add --> ^^^^^^ 方法三：
升级oracle带的jre。
试一试，不知能否解决你的问题。

首先排除安装程序，你先保证安装程序在别人的机器上安装过；
其次要保证你系统的jdk可用，出现这种问题最好安装一个新的jdk版本，1.3.1就可以了
如果这样还不行那我以前的解决办法是重新做系统，可能有某些冲突，其实老奥就这么挑的^_^
