ServiceInstall dependency problem

[bilsla]

The ServiceInstall part of my project fails. There is no indication of failure during the install; the service just does not show up. InstallShield tech-support requested a log file, which did not appear to show a failure. But on closer examination I noticed that the line containing "Executing op: ServiceInstall(Name= etc", there was no right hand parenthesis. The line ended with: "Dependencies=RpcSs" and that's all. There should have been 5 or 6 more ServiceInstall table values. Orca or DirectEditor showed RpcSs[~][~] as it should. I built the project with the dependency removed, and the line in the log file completed as I think it should (last entry shows Description). But the service was still missing, I assume because the missing dependency data. When the dependency was added again, through DirectEditor, the log showed everything properly, but the service was not installed.
Has anyone experienced service install trouble like this? I have tried dozens of variations, with no luck. The command line invocation "app.exe /service" works just fine. I have tried this via both a standard and basic project.
So far InstallShield tech-support has struck out.
Help.
