Another method is to just hold down Ctrl and click on something to deselect it.

Most of the commands come from those dll's, so if those didn't load properly, it's not too suprising that the commands don't work. It seems like there is some serious issue with your install.

Things you can try is to install the newest Visual C++ runtime. Get it from Microsoft here: https://docs.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170 (Make sure to get the x86 version, even if you have a 64-bit OS)

You can also try uninstalling and reinstalling CC3+.

But if this persist, the best course of action is to contact support. You'll find the support form on your registered user page.

That's the result you get if you export it using the "Cosmographer Template" option (It is basically formatted for the Traveller System).

If you just use File -> Save Campaign Cartographer File, you should get a more "normal" result.

Thanks for reporting this. I've fixed this in the original source now, so it will be correct the next time an updated manual is released.

This is how it was with CC3 and older, the data files lived in the installation directory. But that causes all kinds of issues, because only administrators can write to that directory, so if you run CC3 as a non-admin user you get into trouble, and because of Windows UAC which runs everything in non-admin mode even if you are and admin unless you request otherwise, people would always need to right click on the icon and do a run as admin. Keeping the data files with the program itself is going right against the recommended way of doing things on Windows.

All modern programs split their data files up this way. My browser's data folder is found in App data in my user profile, my image editor puts its sample files in my documents directory, my games store their saves and settings either in my documents, or appdata (varies). It is generally a very bad idea to mix user-editable files with files the user shouldn't mess with (program files).

Some programs do allow people to pick the installation path, but CC3+ is so tiny that it shouldn't really make a difference no matter how small a C drive one have. (Note that Windows do actually make it possible to move the program files directory itself thus making all installations go somewhere else, although this isn't straight-forward to set up)
