Below is the response from our software developer about why the installation file was flagged as having a Trojan.
"This is a false positive related to the Advanced Installer that we are using for building our setups. The advanced installer is the only one (as far as I know) that can build a universal executable setup which contains both 32- and 64-bit versions of products and can automatically install one or both depending on the OS platform (another advantage of our SDKs which you can highlight to customers). A couple obscure anti-viruses confuse it with a virus, but it is completely clean."
Here is a link that talks a little about it: https://www.advancedinstaller.com/forums/viewtopic.php?t=19811
