These are all different software. First, please make sure that the software installed in your environment is appropriate for your use. In addition, the functions provided and the layout of the GUI may be changed as a result of version updates.

What version of Windows does it work on?

CubePDF Utility works only on Windows versions within the valid period. There is no guarantee that CubePDF Utility will work on Windows with expired support, and no fix will be made just for it if it stops working.

As for Windows 10 and Windows 11, considering the framework and libraries CubePDF Utility uses, we believe it is unlikely that there will be a situation where CubePDF Utility will not work on a specific version. For this reason, we will only announce when there is a specific problem, and in other cases, we do not plan to specify whether or not each version will work. In the end, please install the software yourself to determine whether or not it works and whether or not you can use it.

As for Windows Server, for the same reason, we expect it to work basically without problems. In addition, we have received many reports that it actually works. However, due to the fact that we are not able to conduct sufficient testing in the development environment, we may not be able to verify or solve problems specific to some server editions when they occur. Please be aware of this.

Are any runtimes, frameworks, etc. required?

.NET Framework 3.5 or later (4.7 or later is strongly recommended) is required to use CubePDF Utility as it is developed using it. .NET Framework should already be installed in most cases, but if you need to install it, you can download it from Download .NET Framework.

Note that the executable file to be installed for CubePDF Utility differs depending on the installed version of .NET Framework. Therefore, if you update the .NET Framework version, it is recommended to reinstall the CubePDF Utility as well.

How do I update my version?
