[Closed]registering DLL and OCK files

you need to run regsvr32 from windows\SysWOW64 for 32-bit libraries

For 32 bit DLLS in Windows 64 bit platforms:

1. Copy whatever.dll to c:\windows\sysWOW64\
2. Open a CMD prompt AS ADMINISTRATOR (very important)

In the CMD window:

1. CD c:\windows\sysWOW64\
2. regsvr32 whatever.dll

You will then be executing the 32-bit regsvr (c:\windows\sysWOW64\regsvr.exe) on a 32 bit dll
