May I ask again, have you recently installed CDex or was this working then suddenly failed?
The file wnaspi32.dll is not part of Windows - it should have been produced during CDex install and most likely it is present but CDex is unable to load it.
I see that the program is still available for download (dated 2009).
There is some useful information here:
I don't believe that downloading a copy of the file is necessarily the right way forward. If you get it from the wrong website at the best you might get the wrong version number and at the worst a virus. It is more likely that the install itself has failed or is in some way corrupted. You can always search to see if Vista can find the file and whether it is already in the CDex folder or elsewhere on the system.
I recall this program - used to have it on my Windows 98.
Always pop back and let us know the outcome - thanks
