Error in DWSIM Open-CAPE editor
I'm constantly getting this error when i trying to do anything with Cape-open.
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: Não há suporte para esta interface (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
I tried reinstalling the dwsim app thrice but still this error is consistent.
DWSIM


Are you using more than one installation of chemsep in your system? Have you installed all the four components while installing DWSIM?
