Build Failed...Styles.css is denied

[BParker]

Last week everything was fine, now I can't build my project.

When I try to build I get the following message:
Build failed: Access to the path:.....Resources\Stylesheets\Styles.css is denied

Can some one please tell me what happened and how to fix it?
Thanks

Two guesses: The file is open in some editor that has a lock on it. Someone changed permissions on that folder.

Root Cause
This issue happens when the affected files are marked as Read-only.

Solution:

Right - click on the .htm file from go to 'Properties' . Un-check 'Read-only' under attributes

Thanks for the help, but my IT guy turned out to be the problem. He moved stuff around and didn't tell me.

But Thanks again for trying.
