New to manager downloaded but icon won't run

@rsturbolad, this error occurs if you have on Windows installed some program which is using incompatible Windows API. It’s usually some out-of-date antivirus, anti-spyware program, VPN or similar.

There is a lengthy topic on this issue. It contains names of several programs which are known to cause the problems. You will need to either uninstall those programs from your computer or obtain the latest versions of those programs which are fixing the issue.
