Business Intellingence Application Server installation hangs !!!

Question

hello i am trying to install the Oracle Business intelligence 10g Server( the BI components of the AS 10g ) on a Windows XP machine.I know its not supported but no where they say you should not install it, they only say not recommended .
I successfully installed one instance on one machine, but while installing on a second one the Oracle Universal installer just froze at "java security configuration assistant", looking in the log file i found
" Start output from spawned process:
Oracle JAAS [Mon Feb 05 10:37:14 EET 2007]: invoking command:C:\BIToolsHome\ASPlus\dcm\bin\dcmctl.bat resyncInstance "
With nothing , no errors no output nothing !!
and it stayed like that for almost an hour and when i tried to stop this component's configuration also no action occured until i decided to stop the installation becasue i had no choice, i couldnt go forward i couldnt go back and i couldnt cancel either , so i forcively terminated the installation . And when i tried to uninstall , also nothing happened the installer just froze again !
i am trying now to manually complete the configuration using the other machine's log file.
I have googled for this and seen many occurences of the problem but no specific answer, if anybody could help me i'll be grateful.
Thanks

Hello again
this is crazy, i have tried to uninstall the instance following the instructions you gave me Keith but i couldn't , the uninstal process also froze !! can you believe that !
it stopped right at the "Deinstall Products" step of Universal installer with a message saying that i have to run "<ORALCE_HOME>\perl\5.6.1\bin\MSWin32-x86\perl.exe <ORALCE_HOME>\bin\deconfig.pl" before proceeding with the uninstallation in order to properly deconfigure the instance,and that after having this completed,i can continue.
When i ran the command i got (C:\BIToolsHome\ASPlus is my ORACLE_HOME)
C:/BIToolsHome/ASPlus/jdk/bin/java -classpath C:/BIToolsHome/ASPlus/jlib/DeconfigWrapper.jar;C:/BIToolsHome/ASPlus/jlib/ldapjclnt10.jar;C:/BIToolsHome/ASPlus/jlib/ojmisc.jar;C:/BIToolsHome/ASPlus/opmn
/lib/optic.jar;C:/BIToolsHome/ASPlus/dcm/lib/dcm.jar;C:/BIToolsHome/ASPlus/config/Queries.jar;C:/BIToolsHome/ASPlus/jdk/jre/lib/ext/sslqueries.jar oracle.ias.deconfigtool.DeconfigWrapper -o C:/BITools
Home/ASPlus -osso false
OIDhost not found in ias.properties
equired parameter OIDhost was not found in ias.properties. This means that this Oracle Home is not registered with Oracle Internet Directory. To deinstall this Oracle Home, you do not have to run this tool. Instead, you can just run Oracle Universal Installer (OUI) and select the "Deinstall" option.
so far so good, i returned to the OUI and sat their for an hour and nothing happened , it kept displaying the Remove window with the progressing bar stopped at "Synchronizing inventory" (actually the bar never moved it's always at 0)
and that's it !!
can you beat that ?!
and Michael believe me i will never install this software again
