Getting this error message when trying to update to Process Explorer v17.03 in the PortableApps platform.
"The downloaded copy of Process Explorer (https://download.sysinternals.com/files/ProcessExplorer.zip) is not valid and can not be installed. This could be due to an incomplete download or other network issue. Please try running the updater again when complete."
The publisher released a new version but didn't bother announcing it. We've updated our package. In the future, you can let us know in the Outdated Apps Thread: https://portableapps.com/development/outdated
Sometimes, the impossible can become possible, if you're awesome!
