InstallShield 5.5 Pro and services

Hello all, I’m trying to install a driver and service in one installation. I have updated the InServ.ini as follows:

[Services]
service1=filedrv
service2=simple

[filedrv]
ServiceName=filedrv
DisplayName=filedrv
DesiredAccess=SERVICE_ALL_ACCESS
ServiceType=SERVICE_KERNEL_DRIVER
StartType=SERVICE_BOOT_START
ErrorControl=SERVICE_ERROR_NORMAL
BinaryPathName=Drivers\filedrv.sys
LoadOrderGroup=filter
TagID=1
Dependencies=NULL
ServiceStartName=NULL
Password=NULL
ServiceExists=0
StartService=0
ServiceArgs=h
Component=Driver

[simple]
ServiceName=Tantaranka
DisplayName=Aide Kuche!
DesiredAccess=SERVICE_ALL_ACCESS
ServiceType=SERVICE_WIN32_OWN_PROCESS|SERVICE_INTERACTIVE_PROCESS
StartType=SERVICE_DEMAND_START
ErrorControl=SERVICE_ERROR_NORMAL
BinaryPathName=simple.exe
LoadOrderGroup=NULL
TagID=NULL
Dependencies=NULL
ServiceStartName=NULL
Password=NULL
ServiceExists=0
StartService=0
ServiceArgs=h
Component=Service

The installation is giving me the error - Invalid parameter. If I install the two things separately, there is no problem. But when I try to combine the driver and the service in the InServ.ini, the error appears. Can someone help me?

Best:

Mark
