Kindly I ask your attention.
Does the program not start or can't you only open the file or both?
And like shreejan86 asked:
Any error messeges?
I don't know anything about Windows 8,1.
Is it a x32 or a x64 type, this goes for the programs too?
Could you be so kind to let us known which .type file it's all about?
What did you do before it accurd, an update or whatever?
Just need to know, just in case.
Hopefully I let you known enough, that you will find the answers you seek!
Good luck and have fun doing it!
