Have got an InstallShield created vendor MSI to install but it crashes when any self-repairs happen.

"InstallationInfo failed" error occurs at the point where the MSI calls a Custom Action function "OnInstallFilesActionAfter" from "ISScriptBridge.dll"

Execute deferred Script extract:- ..
..
Call DLL from Installation Function InstallFilesActionBefore (OnInstallFilesActionBefore)
Install Files
Call DLL from Installation Function InstallFilesActionAfter (OnInstallFilesActionAfter)
..
..

Anyone know what these InstallShield custom actions do?
or anyone encountered "InstallationInfo failed"?
Is there any documentation to be found listing the ISScriptBridge.dll

These are events that call the InstalLScript code that the author has written (or the default code if he hasn't - where this default code often does nothing)
I think InstallationInfo is the point where it writes some (uninstall) registry information.

Thanks,

Any recommendations as to how to view the this script imbedded in the Binary table?

Is there any documentation listing the different CAs that InstallShield inserts into MSI and of the functions called throught ISScriptBridge.dll list what they do?

The embedded InstallScript is compiled, not human readable. You would have to contact the setup developer to request the source code.

Makes it difficult to see if it a default script or not then

But thanks again for the response
