@flakzeus: MSI installer should be available with the final release

@powder21: unprotected means that the immunization couldn't applied for some reason. Usually, it's another security product, e.g. ZoneAlarm, blocking the immunization.

@Fred51: When you highlight which file exactly?
I just checked, both the installer (spybotsd152rc1.exe) and the installed main executable (SpybotSD.exe) have version available. That it is not 1.5.2 yet is just because it's still the release candidate, the final will have a (or .21 ...) version number.
