Can't reinstall SmartFTP after error.

I got the "Installed product does not match" error as described on https://www.smartftp.com/support/kb/ins ... f2593.html.
 
I uninstalled SmartFTP and downloaded the latest version via https://www.smartftp.com/download .
 
Although I've got Windows 7 64-bit operating system I keep on getting this message:

And I'm redirected to download a different version.
 
Why is that happening?
 
How can I solve that?
 
Thanks,
Eytan
 

The setup is run under app compat (application compatibility) mode.
Try to run the SFTPMSI.exe as Administrator: Right-click the SFTPMSI.exe, then select Run As Administrator

Thanks.
It worked  :D
