upgrade to cube programmer v2.20 not installing

[xuraax]

When i enter the programmer I get a signal to upgrade to v2.20.

The process of downloading appears to be proceeding ok but at the end the program just shuts down. When I rerun again the v2.18 comes up and the system asks me to upgrade again to 2.20.

You don't have to upgrade if you don't want to.

If you want to upgrade, try downloading the standalone installer directly rather than upgrading within the tool.

That is what I have been doing, but it is annoying to keep getting a message to upgrade everytime you need to do something.

On a standard windows install, installing a new version will overwrite the existing EXE.

If you can still launch 2.18 after installing 2.20, maybe you're launching from somewhere that didn't get uninstalled. You could try uninstalling 2.18 first. More details on OS and how you're launching would be helpful.
