I am using IE7 as default browser.While downloading Iterasi plug in for the browser I am prompted that my sysem does not have .NET 2 platform which will be downloaded with the exe. Program.After allowing for the same I could download the set up exe. Program but cannot run the same as a pop up warns that the set up exe. File has changed since it was originally published(this message is from my firewall by Kaspersky)Even after choosing the allow button the set up cannot install the browser plug in.Repeated retries donot solve the problem.How do I get the plugin installed?
