If problem not resolved, when using SysWoW64 version of regsvr32, make sure all library dependencies have same archetecture. For example, when

regsvr32 lib_x86.dll fails to register library, and %SystemRoot%\SysWow64\regsvr32 lib_x86 also fails, try to load lib_x86 to Dependency Walker application to see whole list of dependencies. If any item have 64-bit archetecture, here is the reason, why regsvr32 fails to load 32-bit library.
