Cannot write project file !

Hi there, same problem here.

I’m using STM32CubeMx and Keil uvision V5.28.0.0 for a Microcontroller STM32L100RC in Windows10.

The problem: while creating a new project with STM32CubeMx and trying to open it with Keil I get the folllowing error: error creating \\RTE _components.h Cannot create directory

When I open a project that already exists, Keil give me the following error: Cannot write project file.

Already checked that:

-it has not the read only attribute.

- login with admin credentials so it allows me access

- path name contains no space

- program already re-installed

Any idea about where the problem could be?

Thanks in advance

It's not still open in Cube, is it?

That's not a valid path - is it?

If you open the project file in, say, Notepad - can you write to it from there?

Have you actually tried it? - ie,

• creating a new file in the project location
• editing & saving an existing file in the project location

Note that some applications will keep a file locked after you close it, but keep the application running - you have to fully exit the application to release the lock.

Hi Andy,

Thanks a lot!. The problem was windows antivirus. I have solved the problem  by deactivating the folders.

>>That's not a valid path - is it?

I could definitely see the Computer Saying NO!

might be a better idea to tell your antivirus to not scan project files - then you won't have to keep deactivating folders each time you create a new project in a new location ...
