VERR_LDR_MISMATCH_NATIVE

Post by Motorpsycho »

Hi there,

all of a sudden my virtual machines stopped working giving me the error "VERR_LDR_MISMATCH_NATIVE". I am using virtual box 4.2.4 on a windows 8 host. I already tried several things, reinstalling virtual box, wiping virtual store (which was empty anyways), downgrading to some older version of virtual box and now i am bumped. Any help appreciated, here's my log:

Code: Select all

As far as I know the message usually means a botched install. I'm sure I've seen this message e.g. when someone has been copying executables out of the VBox folder, these will not run when the services they call on change versions.

Basically: uninstall the software, reinstall (in the default location and don't leave anything out), and do not move executables to non-standard locations.
