Title: Fix install command in case of errors

Running "choco install xyx" failed and I got a hard error:

```
The term 'true' is not recognized as the name of a cmdlet, function,
script file, or operable program. Check the spelling of the name, or if
a path was included, verify that the path is correct and try again.

Command 'install' failed (sometimes this indicates a partial
failure).
