I had the same issue and the security.d replaces the current one and conversion program resolved the issue.

Turns out there is a fix for it... there is a "security.d" file in either one or two places (depending on 32- or 64-bit installation) that Epicor Support will send a fix for. He did not reference an SCR, but knew of the problem and the fix as soon as I described it to him.
After replacing the file, you need to run Conversion Program 100 (all users should be out of the system).
