Invalid project path with STM32Cube_FW_F3_V1.4.0
Thank you for reporting the issue and sorry for the inconvenience it may bring
I have reported the issue internally, this will be fixed in the next release
As a temporary solution, you can replace all accurence of "\" by "/" in your .cproject and .project files using gedit or any editor of your choice
Please keep me informed if this does not sovle the issue.
