A deployment fix went into 7u25 deploy.dll that created an issue with IE registration during patch-in-place scenario. This has convinced us that we need to improve our code around the RegDeploy() call. We should do the following:

-no longer treat ssv.dll/jp2ssv.dll as special cases. We should patch them like every other file in the JRE. These 2 files are always locked when IE is open, regardless of whether Java is running. In 6u17, we did a fancy hack to ignore these files, in order to reduce our FilesInUse cancels. We replace these 2 files later in the JRE install instead. This has added complications as there are temporary _patch.dll files present during PnP that is causing issues with RegDeploy.
-We should ping an evar for whether RegDeploy passes or fails.
-We may want to get deployment group to have finer grained return codes, instead of simply true/false.
