creating windows template for vra

I am following this url to prepare my windows 2008 template for vra

vRealize Automation 6.2 Documentation Center

but when I ran

install.bat password=Password cloudProvider=vcac vcacServer=IaaS_Server_FQDN httpsMode=true

There was no darwin_user created

the user created was darwin

not darwin-user

Also I do not see the vra agent installed

dont see much in the logs either

for Iaas_Server_FQDN, I used an ip instead of fqdn since the template is on a workgroup.

any idea?
