On Windows 2000 and later, it now uses Windows' own regsvr32.exe to handle DLL registration/unregistration instead of an internal program. This should address errors seen on Windows Vista when registering certain older DLLs. (Windows Vista applies a compatibility fix known as "WRP Mitigation" to regsvr32.exe, which allows it to successfully register DLLs that attempt to write to system registry keys in violation of Windows Resource Protection.)
Some messages have been added and removed in this version. (View differences in Default.isl)
