I have an application that I can't seem to open. I've exrtacted all the files it just seems to be missing something. Can anyone tell what need to do to install an application from a zip file? Thanks.

Be very careful with zip files, especially if they are small filesize. There are a lot of viruses spread like that.

I you have unpacked it and it still won't install and no error about missing files pops up, then it's either corrupt or a virus... or alternatively not for your operating system.
