Hi,
Normally the runtime files come with the developer version of the software, I'm not sure if the runtime files are available seperately, but have you tried searching the internet to see if the runtime files for your version of access is available serperately from the developer version.

Edit: No sooner had I said the above I did a quick search of the internet and up pops downloadable runtime files for Access 2013. So all you need to do is search for them and you will find them.

John
