Certificate Error

Question / Problem

I get a Certificate Error on start. How do I fix this?

Answer / Solution

Treesize.exe is digitally signed using an AuthentiCode certificate issued by GlobalSign. One possible cause for this error is that the GlobalSign root certificate is missing, so the certificate chain is broken. The GlobalSign root certificates are deployed through Windows updates and during the installation of TreeSize.

There are only two possible resolutions if you want to use our products on that system:

• Install the product using our installer, or
• please make sure all available Windows updates are installed on this system.

In the unlikely case both options did not resolve the option, please point a Windows Explorer to “C:\Windows\JAM Software\TreeSize\”, right click on TreeSize.exe, select “Properties”, go to the tab “Digital Signatures”, select the item “sha256”, then press the “Details” button, then press the button “View Certificate”. Please send us a screenshot of the tab “Certification Path” of the dialog window which pops up then and a screenshot of the actual error dialog.
