Hi,I'm taking a course in FPGA design and is using Quartus Prime Lite 16.1 (Free) and constantly run into permission errors.The latest one is during compilation.Error (138001): Cannot write to directory C:/nnn/AlteraPrj/pipemultQP16_1/Schematic/incremental_db, which is required for storing incremental compilation results.I simply can't find where and how the permission is denied. I've added as much permission as I can in the security-tab in the folder option.Best Regards/Anna-Karin

So (one solution anyway):I updated to 25.1 (might not have been necessary)I started Quartus as administrator (but this was not enough)Finally I moved the project folder outside my OneDrive/System managed folders

Compilation Error (138001) Write permission

Try trashing the db and incremental_db folders and compile again.
Any reason why you must use 10 year old software?

  Didn't work, so I guess i MUST update SW.
  I'm using an online course, through my employer, that needs some updates. I hope I still can use that example files and setup.

Please try running Quartus in Administrator mode, or consider changing the project directory to a different location (for example, outside protected or system‑managed folders).
As sstrell mentioned, Quartus Prime 16.1 is a legacy version and is now quite old. No further technical support is provided for this version.
I would strongly recommend installing and using the latest supported Quartus version
