    Question

  •  

    because I had a problem with a dll that was corupted and coulden't been enymore used by OWA, I decided to reinstall Client Access role. So, I've uninstalled the CA role using setup /mode:uninstall /role:CA without problems, but wen I'm trying to reinstall it I have the folowing error. The same with the graphical wizard.

     

    E:\>setup /mode:install /role:CA

    Is this for real? Has anyone tried this. I am having the same problem with CAS. I cannot install it or remove it.

     

    Thanks,

    You will receive this error if you try to reinstall the role from your original installation files/CD after you have applied SP1 to your server. If that's the case, the solution is to reinstall the role from the SP1 setup.
