Sorry guys! we were silent for a long time. Our team was too busty or enjoying annual breaks.
We noticed recent comments complaining about failing to install oracle database and developer suits.
Please please, read the enitre post thoroughly, then try to install the product as suggested with the post.
No Oracle proudcts were certified for Windows 7 when we posted the work arounds. These are just work arounds and you would hit the “jackpot” only if you would follow the post as it is!
