Have Windows7 and get confused and frightened I will harm my HP. Has to be super simple and pictures and step by step easily done.
Directx is part of the Windows installation and cannot be removed. Doing so will most likely corrupt the registry.
When I try to install treasure in the royal tower all that pops up is an aplication that says modify repair or remove all installed content. Currently I have 10. If you follow the instructions for older games, you should be able to install them just fine.
