@davidg Good to hear from you again. I always liked your support.
"Semantic Bundle is a suitable alternative if you cannot run Composer
to install or upgrade SMW (1.9+) and a number of other extensions that
require Composer, such as Maps (3.0+). Do not run Composer if you want
to install Semantic Bundle."
However, the preferred way to install Semantic MediaWiki is still by installing Semantic Bundle as I mentioned above. This is essential to use Semantic MediaWiki with forms.
