All our installation programs are digitally signed by our software developer, Dexadine, Inc.

So why should you care? Because it's statistically improbable that a digitally signed program can be altered in any way without invalidating the digital signature. Thus, if the digital signature is OK, you're assured that the program is exactly as it was when it was signed. If a file gets corrupted during download, infected by a virus, or modified by someone else the digital signature will be invalid.

Corruption of a file by the download process does occur often enough that it's prudent to check the digital signature of any setup file you download before running it to install software.

To verify one of our files, open either File Explorer, Windows Explorer, or My Computer and browse to the folder where you downloaded the file to and then right mouse click on the file name. In the menu that pops up select Properties as shown below.

The Properties dialog opens and displays a number of tabs near the top. Select the Digital Signatures tab and you'll see Dexadine, Inc in the Signature list. Click on that name and then click the Details button to open the Digital Signature Details dialog as shown below.

If the file is exactly as it was when it was signed it will say This digital signature is OK and Dexadine, Inc will be listed for Name in the Signer information box. At that point you know you have a good copy of one of our files.

However, if there has been any change to the file you'll see the message This digital signature is not valid as shown below.

If a file's digital signature is not valid, delete it and download it again and then check that file's digital signature. Only run the file when the digital signature is OK.
