AutoUpdater.NET: Extractor fail to extract/replace all or some file

I face an issue lately (I believe this is happening after the latest Windows update), where in some cases the extractor fails to extract/replace some or all of the files.

private void SoftwareUpdate()
{
        AutoUpdater.AppTitle = "PayrollPlus";
        AutoUpdater.LetUserSelectRemindLater = false;
        AutoUpdater.RunUpdateAsAdmin = true;
        AutoUpdater.ShowSkipButton = true;
        AutoUpdater.Start(@"https://www.codeworks.com.cy/cw!Downloads/PayrollPlus/ver-10.1/updater/updater.xml");
}

This happens both with version 1.4.10 & 1.4.9.

I do not know why this is happening. The extract path is C:\Program Files (x86)\Codeworks Ltd\PayrollPlus
