Just wanted to update this. I, too, am a Win7 user and also found that DaVinci Resolve became "broken" on my system after v.14.2. But I found this thread (some years later) and was enthused to try it. I grabbed the most recent Resolve (16.2.3) and Sandboxie (now released as freewqre) and gave it a go. First, I tried installing Resolve using SandBoxie. That didn't even allowed Resolve to finish installing. Wiped that clean and tried again, this time installing Resolve and then using Sandboxie to run it. That didn't work either. So I got rid of both. Then, not wanting to give up, did more searching and came across this YouTube video - "How to run DaVinci Resolve on Windows 7 and 8? The procedure entry point DeleteCrytical... error" (). A few users had other problems (too weak hardware, too old video drivers and/or .DLL files), but for most it worked ... me included! It's so simple. Just install Resolve. You must be online while doing this to allow Resolve to grab additional parts from Blackmagic Design. After installation, when you run it, you'll get an error message "Resolve.exe Entry Point Not Found -- The procedure enty point DeleteCriticalSection could not be located in the dynamic link library api-ms-win-core-syngh-l1-2-0.dll" and it will not run. The YouTube video tells you to find "opencl.dll" in the Resolve folder and rename it to "openncl.dll" (adding another "n" so the program will not find it). Run Resolve again and this time it will run (no error messages). That's it! Then it works! The Blackmagic Design programmers really need a flogging for not fixing such a nonsensical code error, which prevents untold numbers of potential users from getting hooked on their software. Then again it is buggy software -- meaning you can't do anything you want. You must "learn" what it can do, and do only that. Anything else produces wrong results, or it crashes. (For "free" we can't complain too loudly, I guess.) *rolleyes*
