[Oracle-l] ORACLE universal installer did NOT generate response file

I tried to use ORACLE universal installer "record"
function to de-install ORACLE 9i or 10G software. it
work correctly on install software (will generate
response file), but deinstall software does NOT
generate response file.

Procedures I doing are:

put 10G software CD in

d:\setup -record -destinationfile c:\deinstall9i

click "deinstall product"

click oracle9i

click "close" or "remove"

Anyone know why?

Thanks.
