Windows Digital Signature verification won't allow my scanner to run.

[Michael Japzon]

We have seen some instances of various scanners unable to connect with their internal device drive due to a problem with Digital Signatures:

"Windows cannot verify the digital signature for the drivers required for
this device. A recent hardware or software change might have installed a
file that is signed incorrectly or damaged, or that might be malicious
software from an unknown source. (Code 52)"

It appears that a windows update has caused problems for a number of drivers.
