My file I bought wont open :(

I downloaded a menu template, And have tried t open it with no success. I have found that its an INDD file, Now… This is only found using Adobe indesign program. Not cool because i went and downloaded the Adobe InDesign software and there is running issues that when a fix becomes available, they will let me know. How can I get this software I bought from here to open in a new format so I can finally make my menu… sighhhh

If it is an InDesign file then it will only open (properly) in that software. All files have a file type in their descriptions that highlights this.
