Any way to download update files

Hi,

I'm helping someone out at the moment updating a couple of their computers. I'm installing microsoft dynamics RMS store operations on a new machine but I don't seem to have the necessary files to update to 2.0.6, I can only get to 2.0.4 but the database is updated to 2.0.6 so I can't access anything from the manager or the POS.

I tried the company that set it up originally but they seem to have gone out of business. It seems to get the files I need I have to log in to download, but all I have is a handful of information scribbled which doesn't include any details that help, is there any other way I can get these files? 

Thanks in advance
