Do one thing
Delete this oracle key.Do a fresh installation as fromyour attach file shows that u have other oracle versions isntalled there.
Note: Doing any thing on Win95 as is Rock age system is not preferrable.Rather than wasting time better do testing on good system with good configuration as this is going to solve lot of your problems.
