I'll TRY to make this short.  I currently have Directx 8.1 on Windows XP Professional.  Want to run a new game that needs DirectX 9.0.  Have tried downloading complete DirectX 9.0 - Redist from various sites.  When the "Install to" BOX comes up the box is blank.  Most downloads automatically point to the correct directory to install to.  Where do I need to install DirectX 9.0 on Windows XP Professional.  On my Win98 SE, DirectX is installed in Windows/System.  When searchhing  files and folders on the XP I have about 10 items that come up (possibly half or more from failed downloads).  It looks as if the current copy of DirectX 8.1 may be installed in Windows/System/Win32.  Can someone PLEASE point me in the correct direction.  What destination goes in the blank "Install to" box?  I read somewhere that if a program requires a HIGHER version of DirectX it will be INCLUDED with the game.  I am on the verge of making a trip to Wal-Mart and reading all the fine print on the program boxes for one that includeds the DirectX 9.0 upgrade.  Please help!Have you tried going to windows update?
