vb ActiveX Cannot Create Component error

Hi,

I created a doc to pdf converter and it works fine if run on computers with microsoft visual studio installed.
However, if I run the built program on PCs that do not have visual studio, once I click the "convert button" I get this error:
"vb ActiveX Cannot Create Component error". Thus, the program, if run on machines that do not have microsoft visual studio installed, open up but does not convert the file from doc to pdf.
I also tried the Setup and Deployment option but no luck! :(

Hope some one will help.

Thank you,

A.
