Go 1.9 gives runtime error on Windows 10

I installed Go 1.9 on Windows 10 and when I ran a class 'Hello World' program it gave me the following error.

# runtime

When I ran go env, it gave me the following output,

Really weird issues in the runtime with no obvious cause are often caused by not uninstalling a pervious version before installing the new one.

Sadly the Go installation instructions make no mention of the issue.

In general you should move or delete your old Go install, and install the new version from scratch.

If you are building from source (the way I do) it is best to move the old version to a diferent directory, and then configure a temporary environment so you can use the old version to build the new one. If installing from the official binaries just deleting the old version is simplest.

Regardless of how you are installing you should never place your own code in the same tree as the runtime code, so just deleting the old runtime and reinstalling/rebuilding should always be possible.
