Well.. sorry. I suppose I might have copied them in there manually to try and get SU to use those versions. It seems I remember a previous post awhile back about SU using old msvcrt versions.

Anyway, the point of the post was where are the DLLs. They are usually put by the application installer into the Windows/System32 folder and registered using regsvr32.exe, but normally the installer is not supposed to overwrite newer versions with older versions. If an application must use and older version, it can keep a local copy in it's program folder and specifically load the local copy. (Which may be how I ended up with copies in the SU folder, I was trying to see SU would use those instead of the ones in my Windows/System32 folder. I have a problem with the MCVCRT and I cannot update several applications, including MS Visual Studio and .NET; something has gotten 'out of whack' on my machine.)
