You can start the Widget manually by executing the jv16Widget.exe from the program's installation directory (c:\program files\jv16 PowerTools\).
To ensure an Anti-Virus product does not block jv16 PowerTools from analyzing your system, simply add "c:\program files\jv16 PowerTools\" to the AV product's exclusion list. If the AV product requires executable files to be excluded, then please exclude all the executable files from c:\program files\jv16 PowerTools\.
