I did read the "readme" file, I did not see anything about "Open with?" How do I begin the installation? I try 7-zip- it still asks, what program to open it with.  Thank you.

You should be able to start the install by clicking on the 02Sonar X2 part1 of the installation files. You need all 4 files in the same directory.

Your antivirus interfeared with your download. Its no good! Download one section at a time and make sure your antivirus is disabled

Thanks for the antivirus tip- I forgot to disable it, so I did now, but it still asks what program to open it with. Isn't there supposed to be "Setup" file? I click on part one- it asks what to open it with.

Vlad, if it's asking that- you may have the dreaded "no .exe" problem.  Did you use I.E. as your browser?  

yes, I did. Also all files have a number next to it, like it says, part1[1] and no .exe. However, it does not usually show extansions- it can. When I click on a link to download, it gives me option to Run or Save. So I chose "Save", and now when I click on a file, it asks "Open With". I really do not have time for this drama. IE is main Windows browser. It does not say anywhere I should not use it. Ugh. There was another thread about something simmilar today- wondering how it called.

Still not resolved :)

So I used 7-zip "Unzip here". It opened 3 bin files, and still, clicking on them, it asks what program to open with. C'mon, it got to be something easy. Any ideas?

Pleause use firefox to get the proper download !!

You have to open all the 4 parts, with 7-zip, in the same directory. you get 11 files (setup-1 to 10)
and a "content" directory.
 the setup.exe is in the last part.
