Or just uninstall 15.1 if you don't plan to use it after 16.1 is installed (which I assume is likely the case). For legacy device support, I have both 13.0sp1 and 16.0 installed, and just play with ENV variables to select which version I need to use for a particular design. --- Quote End --- Thankyou,ak6dn.
