HI ,
I suggest this might be file associations.
I suggest you download a good quality zip tool
izarc (free)
Then open the program -
In the toolbar go to Options - Configuration - File associations - tick zip, tar, rar or whatever you wish to run.
If this doesn't work please get back with details.
Thanks
