Qt installer framework doesn't extract archives

DevAlone

I have created two packages and in second of them following config:

<?xml version="1.0" encoding="UTF-8"?>
<Package>
        <DisplayName>Example of courses</DisplayName>
        <Description>Examples for demonstrating capabilities of program</Description>
        <Version>0.1</Version>
        <ReleaseDate>2017-08-11</ReleaseDate>
        <Default>true</Default>
        <Script>installscript.qs</Script>
</Package>

and following script:

function Component()
{
    // default constructor
}

Component.prototype.createOperationsForArchive = function(archive)
{
        component.addOperation("Extract", archive, "@TargetDir@/subdir/");
}

But it just copies archive file(.zip) to @TargetDir@/subdir/
TargetDir is program files if it does matter.

I have found solution. Qt installer framework doesn't work with .zip. Archive must be 7z http://doc.qt.io/qtinstallerframework/ifw-component-description.html#data-directory
So stupid mistake...
