I’m having the same issue. I am fairly certain it is due to corporate lock down of certain functions due to security policies, since I’m multi-core and non-VM. The system is locked down to prevent rogue applications from installing malware, and unfortunately innocent programs get caught as well. I can install and run certain software, but others give me problems like this. I have the same issues with CubeMX. I’ve figured out how to work around those issues with that program, but I’m new to OpenSTM32, and have not figured out how to do that here yet. I’m trying to port some rather complicated projects from IAR, and haven’t even been able to make a Hello World yet due to lack of ability to install the StdPeriphLib code.
