I was travelling for the last few days. I saw your post on my phone. I had to wait till I got home to find my older posts that I put on the forum because I ran into VERY similar issues with a new, small PC tablet I purchased last December. I kept getting DLL errors. I never got any real assistance from Carbide 3D, but someone pointed me to this thread that got me pointed to my solution: Carbide Motion Startup Error
Basically, I searched on YouTube for a video from “Tom’s Hardware” that helped me find the fix. I had already downloaded and installed the 2013 Visual C++ distribution for Windows 64 bit, but the video said to get the one for 32 bit as well. Once I did that, the DLL errors stopped and Carbide Motion started working for me. Hopefully, it will work for you, too.
