Can DX10 Be Overwritten by DX9x?

By BorgInva ·
Vista Business has DirectX 10. If some games and programs require DX9x (9c mainly), can DX10 be overwritten? People say it can not be, but since DX10 is not downloadable, that I can find, not a chance to just take without asking some other professionals.

Anyway this isn't an Issue as you can load Direct X 10 onto XP Systems so this isn't an Issue.

XP Gets DX10?

Really? Last I checked, DX10 was only for Vista and came preloaded. Well well well, I better check this out in the morning.
Would it be the same distribution, for Vista, as the one for XP? See, I did not know this could be done now on XP, so I did not see the need to state this was for Vista, which is the OS I am concerned for.
Thanks for the info. Will keep you posted.

As there is only 1 DX10 installation File

You use the Vista one and this can be loaded onto a XP System though M$ do not support this option.

Depending on your Hardware it may take a bit of mucking around as well but it's fairly straight forward.

So any games that specify DX9c are already catered for within DX10. :)

I tried it with some games that still wanted DX9c installed, by their own setup, and refused to work (and crash) without it. Probably a problem on the side of the game's setup.

Vista Support in mind.

Perhaps there is a Patch or Fix from the Games Makers to run the problem items on Vista. If they are new or at least Current Generation Games there should be.

That my old DX9 games play fine under Vista.

Well fine if you mean, run without any issues.

They are noticeably slower than on the same hardware with DX9/Win XP.

My problem is that some games/programs not ask if they can install DX9x, but will fail install if canceled from that part of setup. I do not mean I can cancel and still use the program. I mean it will refuse to continue the installation if I cancel form doing DX9. So, my fear is, if I say "yes" to install DX9, am I going to loose 10?

Should not

But, I would image the system just in case. Most of the MS updates will detect the newer version and just quit the install.

Good luck!

Clicking "Yes" allows the system to detect a 'newer' DX version...

It should then abort the DX9x installation.

Whatever it does, it cannot overwrite a file that it doesn't have in its installer. :)
