I created a small app so I could go through all the step of creating an app. My computer's operating system is MS Windows Vista Business. I have tried two unzip programs and each report an error in the souce code file. Any suggestions?

This is a strange report, I've not heard of anything like it before. It could be that you don't understand what unzipping an archive is. Unzipping utilities don't understand source-code and have no ability to 'analyze' anything. Also, it's unusual that you would use two unzip programs to unarchive the download. Simply right-click the file then choose Unzip or Unarchive If you can't see the files included in the download, you won't be able to use Eclipse to work with your project. Focus on unzipping the archive without any special software or utility, your Windows machine will do this wihtout installing anything ;-)

The source-code file I downloaded is named buzztouch_v14_AndroidB130730D81EC45D4.zip. It is my understanding that I had to unzip this file before using it with Eclipse. Is that correct? If so, I loaded buzztouch_v14_AndroidB130730D81EC45D4.zip onto another Window Vista based computer to make sure my system was not correupted. I then right-clicked on the file and selected Extract all. Windows Vista could not extract the file and gives an error. Is there a way I can send you a copy of buzztouch_v14_AndroidB130730D81EC45D4.zip ?

Yes, that is the file you are needing to unarchive (unzip)... send it to info at buzztouch.com and I'll see what I can come up with?

I just downloaded the same source-code file using another internet service provider. This time the file unzipped without a problem. I suspect the original file I downloaded several times, was corrupted by my HughesNet (satellite) internet service rovider.
