Ticket #10592 (new defect)
Documentation for "Restoring d3d8.dll and d3d9.dll" is incomplete
|Reported by:||rgsteele||Owned by:|
A recent version of the Guest Additions installer on Windows implemented a check for "corrupted" versions of d3d8.dll and d3d9.dll. When the installer discovers an incorrect version of one of these files, it opens the following URL in the user's web browser:
The instructions for Windows 7 are to replace the following files from the original Windows media:
C:\Windows\System32\d3d9.dll C:\Windows\SYSWOW64\d3d8.dll C:\Windows\SYSWOW64\d3d9.dll
The instructions are incomplete, however, as the guest additions installer also checks for incorrect versions of the following files, and fails if they are found:
C:\Windows\system32\dllcache\d3d9.dll C:\Windows\SysWOW64\dllcache\d3d8.dll C:\Windows\system32\msd3d9.dll
I believe the first two files can simply be deleted as they are merely cached copies. The third, msd3d9.dll, was not present on the Windows media I was using, and I suspect it can be deleted as well.
The documentation should be updated to include instructions about deleting these files manually. Alternately, the installer could delete these files itself.
