Thanks José. Your response is similar to how I resolved the problem but not exactly the same. I looked at the uninstall String in the registry then came up with the following...

1. Change directory to C:\Program Files\InstallShield Installation Information\{F653AB56-DB37-415B-8DDD-EF5BC1982150}
2. Record removal using "is_setup.exe -l0x09 UNINSTALLING -r -f1D:\temp\SA9app.iss"

This saves the iss file to D:\Temp\SA9app.iss

I then copied this file to D:\temp on the target system:

1. Change directory to C:\Program Files\InstallShield Installation Information\{F653AB56-DB37-415B-8DDD-EF5BC1982150}
2. Remove App using "is_setup.exe -l0x09 UNINSTALLING /s /f1D:\temp\sa9app.iss /f2D:\temp\sa9app.log"

The /f2 switch creates the log.

One problem I encountered is that some files could not be removed and I received the following message:

Setup has detected that some items have not been removed. Setup can present a list of items which can be selected individually for removal. Click YES to see the List. Click NO to skip viewing the list"

I tried selecting YES and then some additional options but the responses are never correctly recorded. The only acceptable response seemed to be to select NO to the prompt, otherwise the .iss response file would not generate a silent uninstall and the same question would be present when the Uninstall was run.

If anyone knows how to resolve this additional little annoyance, please let me know.
