UltraISO has long had a problem with enforced DEP. With EMET 3.0 and earlier I could add the app, uncheck the DEP box and it would run fine. However, with EMET 3.5 on Windows 8 x64, it does NOT seem to honor the DEP exception. Every time I launch UltraISO I get the EMET notification about a DEP violation.
My system is set to "application opt out" for DEP protection.
