The error, "Error: Object is currently in use elsewhere at System.Drawing.Image.get_Width()" is typically caused when using the anti-virus software Kaspersky. Ensure all Kaspersky updates have been installed.
If the error still persists, temporarily disable the anti-virus software, and attempt to open Boulevard. If Boulevard opens, we recommend getting further assistance with your anti-virus software, or switching to a different anti-virus solution.
