**** Build Finished ****

Ideally you want to avoid spaces and special characters like '&' in all paths - (ie) workspace and project path, temp environment variable path, as well as paths where CCS and compiler tools are installed. Is that the case in your environment?

I changed the account name to Admin

And changed the workspace directory

but still have the same above error

What is your workspace directory and to which directory do you have CCS installed?

Could you save the complete build log to a text file (as described in this page) and attach it here?
Or even better if you could zip up the entire project folder and attach it here for us to review.
