Thanks for reading my post.

I'm posting on this thread because I am having the same problem than alanjune had. Tried the solution described above by Elder, but Happy DX uninstall failed to work on my win2k sp4 machine. So it made no sense to attempt yet another directx re-install. I read the read.me, and made sure TEMP and TMP were on C: and find.exe was at Winnt\system32. After a manual reboot, DX was not removed. A few more details may help:

A major system failue 3 weeks ago forced me to do a major repair, a system state backup, plus another repair. Also used a registry fixer after I got the system back up. I may have removed two important registry entries, the same as those posted above by alanjune.

All programs work, including two old dos programs, except Real Flight, a RC flight simulator (falls into the "game" category).

I get the same error message when I try to start the simulator (game), and when I run dxdiag.exe: The procedure entry point GetRawInputDeviceInfoW could not be located in the dynamic link library USER32.dll

The diagnostic info, regarding two missing registry keys, from dxdiag.exe is exactly the same as that posted above by alanjune.

I tried a new install today of directx 9.0c and dxdiag shows that all files required are present. All sound and display tests work fine, except for the two missing registry keys described by alanjune.

PC diagnostics done in Avanquest system suite 8 show all hardware is working OK

I tried several different versions of user32.dll at the location C:|WINNT\System32, and none resolved the problem. Currently a user32.dll version dated and sized 03/06/2007 and 381,200 respectively, is in place. I have two other versions, 06/19/2003 403,216 and 04/21/2005 419,600 that could be tried.

Registry and disk have been defragged, and display, sound and system runs very fast and appears clean in all other respects. Can play a CD move fine.

Have run out of ideas to repair this probelm, and would appreciate suggestions for new solution paths.

My best, Peter, Nederland, Colorado
