Installing 32Bit Windows Service on 64Bit with ManagedInstallerClass.InstallHelper

Question

Is there any way to force ManagedInstallerClass.InstallHelper to use 32Bit. I have a Windows Service compiled for x86 only and I'm trying to use an application built for x64 and ManagedInstallerClass.InstallHelper to install the Service. Is this possible?

Thanks,

Ken

Hi Ken,

Do you get any exception when installing the 32bit Windows service programatically on 64bit system?  I don't think it's a problem.

Good day!

Thanks

Answer 3

Hi Michael,

Yes.

Exception occurred while initializing the installation: System.BadImageFormatException.  An attempt was made to load a program with an incorrect format.

Hi Ken,

I am afraid we cannot let ManagedInstallerClass.InstallHelper be executed in 64bit app to install a 32bit service.   Could you please consider using a 32bit app to install the service instead? 

Good day!

Thanks

Answer 5

Michael,

Thanks for the confirmation. I cannot use a 32bit app to install the service. I will add command line arguments to the Service (/i /u) and launch the Service exe with the Process class.

Thanks,

Ken
