VBox 5.0.0 > Can't install Guest Additions on Win8.1

[superme]

Host > Windows 7 Home Premium
Guest > Windows 8.1 Pro
PC > Asus UX31 (i7 second gen, 4GB ram)

I used VBox without problems up to version 5.0 RC3. After upgrade to 5.0.0, was unable to update Guest Additions on my Guest OS due to the error (attached).
Then I removed Guest Additions 5.0 RC3 and did 'VboxWindowsAdditions /uninstall', rebooted and tried again to install...failed.
I have also WinXP guest and upgraded GuestAdditions to 5.0.0 from 5.0 RC3 here without any problems.

Can somebody point me where my problem can be?

I can't tell you why but this error…

Verifying file "C:\Windows\SysWOW64\dllcache\d3d8.dll" ...
Skipping to file "C:\Windows\SysWOW64\dllcache\d3d8.dll"; not found
Verifying file "C:\Windows\SysWOW64\dllcache\d3d9.dll" ...
Skipping to file "C:\Windows\SysWOW64\dllcache\d3d9.dll"; not found

seems to be the problem.
My Windows 8.1 guest has no dllcache folder and I don't know why the guest additions would be looking for it. I had no trouble installing the GAs.

The lines above don't indicate an error. Just that the installer is looking for a file at different location, and succeed in finding the files, just not there.

The following lines represent what failed to work tho:

Can you zip & attach the file C:\Program Files\Oracle\VirtualBox Guest Additions\install_drivers.log please

Error excuting

Seems to be a typo in the logs.

That's why I said "seems" btw. I wasn't sure. I just knew my install wasn't looking for a dllcache folder.
