Free Evaluation Download

If you would like to give DeployMaster a first hand try, feel free to download the free evaluation version. Obviously, we have used DeployMaster itself to package DeployMaster. The trial version is fully functional and does not expire. You are welcome to use it to create a real installation program and fully test the result.

The only limitation is that the setup applications created with the free trial version will contain a friendly reminder screen saying that you are not allowed to distribute these setups.

The trial version is fully compatible with the full version of DeployMaster. After buying DeployMaster, you can use the full version to instantly rebuild the setup you created with the trial version.

New Code Signing Certificate May Trigger Security Warnings

All downloads from Just Great Software are digitally signed. This allows you to verify that your download came from us and was not tampered with. It also allows anti-malware solutions to do the same, which generally results in less severe warnings or no warnings at all.

The certificates needed to apply such digital signatures expire after 3 years. They cannot be extended. Our certificate has expired recently. This means that DeployMaster 7.4.0 is now signed with a new certificate.

This new certificate means that we are starting from zero with any anti-malware solution that tracks the reputation of publishers by their code signing certificates. This most notably includes the Microsoft SmartScreen filter that is used by the Edge browser and Windows itself.

If you download using Microsoft Edge then it may say that this file isn’t commonly downloaded. That’s because the new release of DeployMaster 7.4.0 is seen as a completely new app. To access the download, click the button with the 3 dots and then click Keep. Edge will then pop up another warning saying to make sure you trust SetupDeployMaster.exe before you open it. To keep the download, click Show More and then click Keep Anyway. Now you can click the open file link in Edge to actually run the installer.

If you download using a different browser then SmartSceen won’t block the download. Instead, when you run the installer you may get a warning saying Windows protected your PC and that Microsoft SmartScreen prevented an unrecognized app from starting. Click the More info link immediately below the message. It should now identify “Just Great Software Co. Ltd.” as the publisher. This indicates that the file indeed comes form Just Great Software and was not tampered with. Click the Run Anyway button to run the installer.

The reason for all this is that the Microsoft SmartScreen filter believes in “safety in numbers”. It sees that thus far only a small number of people have run applications signed with our new certificate. It considers the download unsafe purely because of that. The fact that we’ve been publishing DeployMaster since the year 2000 and that all our DeployMaster releases have always been perfectly safe makes no difference. It sees DeployMaster 7.4.0 as a completely new app signed with a completely new certificate.

If you are using a 3rd party anti-virus or anti-malware solution then that may similarly block the download or block the installer from running until you tell it to accept the download as safe.

Hopefully, in a few weeks’ time, enough people will have clicked the “run anyway” button for SmartScreen and other anti-malware solutions to start trusting our new code signing certificate. In the mean time, we thank you for your trust in our business and our software.
