Well I copied the 5.0.1 release files from C:\Program Files\Oracle\VirtualBox\ExtensionPacks\Oracle_VM_VirtualBox_Extension_Pack to the location of the installed debug version : D:\VirtualBox-5.0-amd64-debug\bin\ExtensionPacks\Oracle_VBoxDTrace_Extension_Pack but I guess thats not correct, as I still get the same error. Anyway, it works for the newly created vm now. - Maarten
