When you run PSoC Creator, check if the log file "PSoC Creator-000.log" is getting generated at this path: "C:\Users\<username>\AppData\Local\Temp". If yes, please share the log here.
If not, please run PSoC Creator and then open the Task Manager. Right-click on PSoC Creator under the Processes Tab > Create dump file. When the crash occurs, a prompt will tell you where the dump file is located. Can you share this file as well? It will give us insight into what's causing this.
Looking forward to your reply!
Hi Dheeraj, and thanks very much for your response.
I completely purged everything on my system related to PSoC creator, which included files that, even when I used the standard uninstall procedures left various files in my user folder (various .dll's). I then reinstalled version 4.3 and then I was able to successfully open my 4.2 project and build successfully after updating some components. So, so far, I am back up and running. If anything changes, I will update this thread.
Glad to hear that everything is working. Also, thanks for sharing how you got things working, it will definitely help other users with the same issue
