    Hi @Sandeep_28 ,

    The Relink ANSYS getting greyed out usually happens when the customization tools are not installed. You might have missed checking the box to install Ansys customization files during installation. If the box is checked and the files are installed, then that option should be active. Please right-click on setup and choose "Run as administrator." Please make sure 'ANSYS Customization Files' is checked when selecting products.
