Our IT plans to host our license server on Linux, will I be able to invoke the 17.4-2019 tools installed on my Windows client systems? The Cadence License Manager works on TCP/IP protocol.

Our IT has implemented IPv6 network at our site, will I be able to invoke 17.4-2019? 17.4-2019 products will not invoke because client-side implementation of IPv6 is still not supported. You would need to configure a dual-stack network consisting of both IPv4 and IPv6. Why will not my licensing work when we cut and paste the new 17.4-2019 features into the existing 17.2-2016 license file? Copying features from one license file to another is not allowed. All licensed features must be generated at the same time or they will not work. Attempting to add these kinds of features into your existing license file will cause licensing errors when trying to invoke products. Use the new license file in its entirety to invoke your Cadence products.
