I have a application and I compiled to an exe file. After I did the setup and installed to other computers, some are working well and some are not. The application was looking OCX file and the error message I gor is "OLE error code OX80040154, class not registered. OLE is being ignored." When I did the setup, should I includ some system files? Is this the reason I received the error message? Anyone could help me? Thanks!
