The error, "Error: Object is currently in use elsewhere at System.Drawing.Image.get_Width()" is typically caused when using some anti-virus software. Ensure all of your Windows and anti-virus software updates have been installed.
If the error still persists, add Boulevard to their exclusion list or temporarily disable the anti-virus software and attempt to open Boulevard. If Boulevard opens, we recommend visiting their support website to receive further assistance with your anti-virus software.
