I have some problems with the NCSU_TechLib_FreePDK45:
- I looked for the file divaDRC.rul for the DRC but I did not find it.
- cadence is not able to integrate the FreePDK45.tf technology file.it shows me an error that it fails to load it.
I think this is the cause of the problem that prohibits me to visualize the low layers of the layouts of the components to interconnect.

Is there another tech library that I can download to solve thes issues.
Thanks

I have no idea if the file you are using is meant for virtuoso. You say the extension is .tf, but other tools/formats also use that extension. The messages don't give any hints about what is going on.

If you change the tech library, you change the technology. I can't possibly know if you are allowed to do that. Is this homework? Maybe ask the instructor/boss/support person...
