Help! Error in CAPE Open Unit Operation

I am currently using CAPE Open Unit Operation for distillation column. But whenever I try to solve the flowsheet, following error appears:

"Unable to cast COM object of type 'System.__ComObject' to interface type 'CapeOpen.ICapeUnit'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{678C0998-0100-11D2-A67D-00105A42887F}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."

I tried searching on the internet but couldnt find a solution. Please help me!

This is because Chemsep and CAPE-OPEN Unit Operation is not properly installed in your system. Please ensure that all the components that you see while installing DWSIM are installed correctly.
