Download Problem

I downloaded winSCP (I believe 5.5.1?) and whenever I click on the setup .exe, it appears to be loading (spinning circle beside my mouse), and the stops after. When I check in task manager, it says there is a running setup fill and a .tmp file, but no dialog box ever opens. Any help would be greatly appreciated.

Thanks for your report.
Can you try to run the installer with /log=path_to_log_file and attach the log here?
