Do you mean virtualizor that is developed by makers of Softaculous? If so, why not get one from them. But as far as I know it does not support windows templates : http://www.virtualizor.com/templates
The Virtualizor support team is very usefull and the response times are fairly quick and it seems they would go the extra mile for their customers. You should open a ticket with their support, they will provide you with the best answer regarding this situation.
just open a ticket and add your on template on the system and you're good to go. but mostly they only provide all types of linux distributions pre loaded or downloadable from their system directly so you might want to check that as well
