__rsignal(RSIG_BOOTENGINE) returned failure, missing definitions?

Thanks for the other link. That does work, but it appears to be an outdate engine. I'm seeing the error listed in this issue on the latest version of the engine. Would love to have a fix as well!

I see the issue, mpengine is doing a lot more work to validate all the signatures on the VDM, and not trusting the host system to do the verification. It might take a day or two, but I'm thinking about solutions!

Same here :(

Thanks for letting me know, I'm investigating.

Using the mpengine.dll from Aug 5 with the newer .vdm files seems to work for now (not familiar with the inner-workings of these files, but it does detect EICAR and several other virsuses correctly).

Thanks for all the work that you put into this project!

Thanks :)

i am also troubled by this problem :(

Same Issue,
Thanks @taviso

Looks like using the mpengine.dll from Aug 5 no longer works with the new VDM files as of this weekend.

@taviso - have you been able to make any progress with this? Thanks again.

I search another download link, it works. But I don't know why. It maybe helpful.

It works fine with older version but latest updated is not supported.

@taviso were you able to figure out the root cause for this?
