Regsvr32.exe in Windows server 2008 64 bit is in two diferent places:
C:\Windows\System32 (here for 64 bit Dlls) and
C:\Windows\syswow64 (for 32 bit Dlls)
If we just run RegSrv32 from cmd we’ll beeing run the 64 bit version and we’ll not be able to install the 32 bit dlls.
we need to run cmd as administrator, go to syswow64 dir, and run regsvr32.exe from that location. That will work.
