Hey LesK,

I apologize that didn't work. We definitely are taking a look at our installer - to see where it is failing to recognize your Operating System.

In the mean time, you can get around this by extracting the .msi package from the installer (so that it will just install the upgrade without doing the operating system and .net framework checks).

Here is how you can extract the MSI package from the installer (after you have downloaded it):

1. Open a command prompt
2. Get to the root of the C:\ drive (by typing "cd/" until it says "C:\>"
3. type the path to the installer
4. add a space and then type /extract=parameter (where parameter is the full path, as well as a name for the extracted MSI, for example: /extract=c:\ppdata\test.msi will create a new file named test.msi within the ppdata folder on the c:\ drive

I've attached a screenshot for your reference of an example of the full command line entry.

Once you have created that .msi file, you can simply double-click it to start the installation.

Let us know where this leaves you. You can always email us at support@pingplotter.com.

Cheers!
