mike, what is the version you are trying to install the agent on? I bet is an old one 🙂  You can see if it is officially supported in AgentsSupportMatrix.xml file.

Since ISScript.msi is the install environment provided by Microsoft, it is probably better and definitely faster to look into the microsoft communities. The first link coming in google:
