not sure if it’s your problem or not :
I experienced the same kind of result when I first tried to install templates
I finally found that template didn’t set up because of the name of the folder uploaded on you template directory
I rembered that some template uploaded were uppercase and the template’s files were waiting for lowercase
Step and step for example
just check in your ACP the template’s code to see if the directory where you uploaded the template is lower/upper case and look at your install to see if it’s the same.
hope it can help
