i have been using the STM32cubeide for years. I have it loaded on 2 laptops. On one I must have made a mistake initially in the setup. It will no longer update to the next release.

The computer has two Solid state drives, C is only 120 Gbytes, D is 1000 Gbytes. Currently the C drive has all the files and programs and is running out of room. What should I do? How can I use the D drive?
