environment: VirtualBox4.3.16, win7 x64‍


when i added custom device EventDevice.dll to VirtualBox4.3.12, everything went well.‍


while i updated VirtualBox to version 4.3.16, started vm, get the error as follow:
VMSetError: Unable to load R3 module C:\Program Files (x86)\Windroye\EventDevice.dll EventDevice): RTCRX509ATTRIBUTETYPEANDVALUE::Value: Bad printable string: ch=0x40: \Device\HarddiskVolume1\Program Files (x86)\Windroye\EventDevice.dll

Can u tell me why?




Is it that Digital signature caused the above problems ? If it do, what are the Digital signature requirements in new version VirtualBox4.3.16 ? Which type of Digital signature can make custom device pass the signature check of VirtualBox4.3.16 ?‍
