COM server creation error - Invalid ProgID after first use of actxserver() with CST MWS

Hi,

I am trying to control CST MWS with MATLAB by creating a COM server using...

cst = actxserver('CSTStudio.application')

as described in the user/application note from CST found at: https://www.cst.com/Content/Support/UserNotes/documents/Application%20Note_Matlab_calls_CST.pdf

After re-installation of CST, this works fine for the first time, but all other attempts after this result in the error:

Error using actxserver (line 91) Server creation failed. Invalid ProgID 'CSTSTUDIO.Application'

and indeed on calling the function actxcontrolselect, the progID is not listed, for it to work again I have to reinstall CST.

I understand this may not necessarily be solely a MATLAB issue (and I have also contacted CST), but does anyone have any ideas???

Many thanks
