If you're trying to open the same file under another account, then you will have to teach your co-workers to launch the software as Administrator under your username. This will give your co-workers permission to run it. However, in case they run the software on their computers, I recommend you send them the installation instructions.
On a side note, I see that the software doesn't appear on the developer's website anymore, which means it's impossible to acquire manuals or troubleshooting documents.
