VirtualBox 5.0.10 error 1790 (VERR_UNRESOLVED_ERROR)

This appears when trying to install any guest on Windows 7 64 bit:

Unable to load R3 module C:\Program Files\Oracle\VirtualBox/VBoxDD.DLL (VBoxDD): GetLastError=1790 (VERR_UNRESOLVED_ERROR).

Result Code:

EDIT: problem solved, logs deleted.

is problem in uxtheme.dll?

[mpack]

If you are using a hacked theme then yes that could be the source of problems. Are you?

[kosamja]

yes, i use custom theme. how to use virtualbox without disabling uxtheme patch (since i cant get uxstyle to work)?

[mpack]

There are no guarantees. However, others have reported success by placing a copy of the unhacked uxtheme.dll file in the same folder as VirtualBox.exe. That way Windows finds the unhacked copy first when finding DLLs to load into the VBox process.

thanks for suggestion, but that didnt work. disabling uxtheme patch before starting virtual machine and enabling it after virtual machine is started seems to work.
