Computer had a problem lost turbo tax 2015 but still have the document. How can I open the document?

[Critter · Accepted solution]

If it is a PDF then any PDF reader can open it  ... if it ends in .tax2015 then that file can only be opened by the 2015 program so you would need to reinstall and update it.

Here lies the problem    No disk found for 2015 to reinstall

Thanks Intuit called me back and got me the program to open things
