Hi there and welcome
It is not slated as compatable with windows 8, and whilst you may get it to function in compatibility mode, you will likely encounter a number of issues using it if you do get it to run.
You would be best to use Microsoft Word to open the files and fist confer them using the Microsoft Works converter which you can get here
Unless you have word 2013 which can open the files by default without any need for a converter.
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
