SUMo Portable is a software update monitor so you can keep track of what installed software is out of date. It's packaged as a portable app so you download on the go and it's in Format so it can easily integrate with the Platform. It's freeware for personal and business use.

SUMo is packaged for portable use with permission from the publisher.

Update automatically or install from the portable app store in the Platform.


ScreenshotSUMo (Software Update Monitor) keeps your PC up-to-date & safe by detecting the most recent version of your favorite software. Unlike built-in auto update features, SUMo tells you if updates are available before you need to use your software. The user can then download the outdated app and update it themselves. Note that not every version of every app will apply to you as beta and custom versions for specific hardware may be displayed.

I am attempting to install Sumo with the installer and I get this error "The downloaded copy of SUMo is valid and cannot be installed." Here is a screenshot:

I attempted to install it on my desktop and on my USB stick. I received the same error on both. If I download via the website it works fine. My system is a Surface Pro 3, Windows 10 x64 , 8gb Ram.
