Thank you so much for this detailed guide! It worked perfectly for me on Ubuntu 24.04. The environment variable section was especially helpful. Anyone struggling with license issues—double check your MAC address and make sure pubkey_verify runs successfully. Really appreciate the time you put into this! I had never written a proper business case study before, and my professor expected professional-level analysis. Feeling stuck, I made the decision to buy case study online through https://academized.com/buy-case-study-online I went with Academized because their site looked professional and easy to use. The writer followed my instructions perfectly, and the final essay was spot-on. I submitted it confidently and used the extra time to prep for an important exam instead.
