I had to install NWare 1.4.3 on my machine for some user training (having had a hardware rebuild, so lost all older versions, and now had only 1.5.3a installed).
Opening a .npa from Windows Exploiter now opens in 1.4.3, which is not unexpected.
But when I go to Open With..Choose Program, and Browse to ...NWare 1.5.3a\NWare.exe, it still opens in 1.4.3. I've tried re-installing 1.5.3a, but that didn't seem to do it.
It would also be nice if the different versions showed up as more explicit than "NWare Application".
Thanks

Phil
You can change the .npa file association.
In Explorer click on 'Tools', then 'Folder Options'.
Select the 'File Types' Tab
Scroll down until you see NPA  (Actuallt pressing the 'p' key will get you most of the way there
Highlight the NPA line and click on the 'Advanced' button
Highlight the 'Open' line and click on the 'Edit' Button
Change the path of and save what gets executed when an NPA file is double clicked or opened.

Thanks Steve,
I'd forgotten that (wrongly assumed that the similar dialogue associated with Open With would perform the same function).
Doh!
