Running vb6 app on 64 bit windows server 2008 R2

i have vb6 app and i have installed it on windows server 2008 r2 64 bit.

but it gives me,

339 - Component 'MSCOMCTL.OCX' or one of its dependencies not correctly registered: a file is missing or is invalid

i copied ocx in system32 as well as syswow64 folders. Still gives me same error. I could not load form having list view control.

But can't register it (If i try to register it gives me error DllRegisterServer failed with error code 0x8002801c).
