Why did you decide to cancel the installation?

It seems like you cancelled the installation of Free File Viewer. Did the installer fail, did you get a virus or malware warning, or what changed your mind?

If the installer failed, then please download this version to avoid the problem - it uses another installer technology.

Did you get a warning from your anti-virus? Sometimes anti-virus products are hit by what is called "false positives" - issuing warnings for legitimate products. Sometimes installers are blocked just because they are not used by as many people as more known software products - how fair is that to small vendors?
