I have a windows service. In the Properties I have the platform target set as X64. In my csproj file I have changed all instances of prefer32bit to false. I am installing the service with installutil.exe when I install and run my service it runs as 32 bit. I am currently building in debug mode. What am I missing here?

Just to add to this old answer, yes use Process Explorer. You can right click on the columns and select Image Type to show which processes are 32 bit and which are 64 bit. Run Process as Administrator to see some services.
We do have third party tools as well as reference a c++ managed assembly. These may or may not be built for any CPU. In fact i know that the c++ managed assembly is only built for x86. However, the odd things is that if I specifically specify x64 the process will start up and work in x64. If the framework were to attempt to load the c++ managed assembly it would fail. I don't mind this, because in the code, we do not load the 32bit managed ++ assembly if we're running in 64 bit mode. Could it be that the build figures that since there is a 32 bit assembly in here it should mark the launching process (in this case a windows service assembly) as x86?
I had this issue when a previous version of the service had been 32 bit. I knew the currently installed one wasn't (checked CORFLAGS), but the process associated with the service was being created as 32 bit anyway, and for the life of me I couldn't work out why.
To get around this problem, please run installutil.exe outside of the appropriate Framework/Framework64 directory. If you have a snap-in built for ILONLY (ILONLY indicates that the executable contains pure IL code and can run either as 32-bit or as a 64-bit process), but want to register it under the wow64 hive, use installutil.exe that is available in the directory %windir%\microsoft.net\framework\v2.n.n.n. For the 64-bit hive registration, run installutil.exe from the directory %windir%\microsoft.net\framework64\v2.n.n.n.
Is it possible to add my own Windows service (myservice.exe) in a WinPE 64bit image? myservice.exe is 32bit applicatication that relies on the winusb driver.
How can I add (manually) my own service in a WinPE image? Or how can I start it after I boot from my WinPE image? sc.exe is not available in the image. Even if I added the right entries in the Registry for the service, it is not shown by wmic service. So net start service_name will return "the service name is invalid net helpmsg 2185"
Is it possible to inject the winusb drivers in a WinPE 5.0/10 (Windows 8.1/10) image?
The 64-bit versions of Windows use the Microsoft Windows-32-on-Windows-64 (WOW64) subsystem to run 32-bit programs without modifications. The 64-bit versions of Windows don't provide support for 16-bit binaries or 32-bit drivers. Programs that depend on 16-bit binaries or 32-bit drivers can't run on the 64-bit versions of Windows unless the program manufacturer provides an update for the program.
This article describes some of the compatibility considerations for running 32-bit programs on the 64-bit versions of Windows. This article doesn't compare the 32-bit and 64-bit versions of Windows, or different 64-bit operating systems. This article assumes that you understand the difference between 32-bit binaries and 64-bit binaries.
The WOW64 subsystem enables 32-bit programs to run without modification on the x64-based versions of Windows. The WOW64 subsystem does this by creating a 32-bit environment on the x64-based versions of Windows. For more information about the WOW64 subsystem, see the "Running 32-bit Applications" topic in the 64-Bit Windows section of the Microsoft Platform SDK documentation. To view this document, visit the following Microsoft Web site: Running 32-bit Applications.
The WOW64 subsystem creates a 32-bit environment on the x64-based versions of Windows. Some 32-bit programs may run slower on these operating systems than they would on 32-bit versions of Windows. Alternatively, some 32-bit programs that require lots of memories may exhibit increased performance on the x64-based versions of Windows. This performance increase occurs because the x64-based versions of Windows supports more physical memory than the 32-bit versions of Windows.
For more information about the differences in memory management between the 64-bit and 32-bit versions of Windows, see the "Virtual Address Space" topic in the About Memory Management section of the Microsoft Platform SDK documentation. To view this document, visit the following Microsoft Web site: Virtual Address Space
A 16-bit installer is frequently used to install and configure a 32-bit program. Additionally, some 32-bit programs require 16-bit components to run correctly. Although 32-bit programs that require 16-bit components might run correctly after they're installed, you can't use the 16-bit installer to install a 32-bit program. Programs that require 16-bit components can't run on x64-based versions of Windows.
If a 32-bit program that requires 16-bit components tries to run a 16-bit file or component, the 32-bit program will log an error message in the System log. The operating system will then let the 32-bit program handle the error.
If a 32-bit program tries to install a 32-bit driver on a computer that is running an x64-based version of Windows, the installation of the driver fails. When this behavior occurs, the x64-based version of Windows reports an error to the 32-bit program.
If a 32-bit program tries to register a 32-bit driver for automatic startup on a computer that is running an x64-based version of Windows, the bootstrap loader on the computer recognizes that the 32-bit driver isn't supported. The x64-based version of Windows doesn't start the 32-bit driver, but does start the other registered drivers.
To determine whether a program requires a 32-bit driver, install and run the program. If the program generates an error message, contact the manufacturer of the program for an update that is compatible with the x64-based versions of Windows.
The WOW64 subsystem isolates 32-bit binaries from 64-bit binaries by redirecting registry calls and some file system calls. The WOW64 subsystem isolates the binaries to prevent a 32-bit binary from accidentally accessing data from a 64-bit binary. For example, a 32-bit binary that runs a .dll file from the %systemroot%\System32 folder might accidentally try to access a 64-bit .dll file that isn't compatible with the 32-bit binary. To prevent this, the WOW64 subsystem redirects the access from the %systemroot%\System32 folder to the %systemroot%\SysWOW64 folder. This redirection prevents compatibility errors because it requires the .dll file to be specifically designed to work with 32-bit programs.
For more information about file system and registry redirection, see the "Running 32-bit Applications" topic in the 64-Bit Windows section of the Microsoft Platform SDK documentation. To view this document, visit the following Microsoft Web site: Running 32-bit Applications
The WOW64 subsystem redirects 32-bit binary calls without requiring changes to the 32-bit binaries. However, you may see evidence of this redirection when you perform some tasks. For example, if you type a command-line script at a 64-bit command prompt, the command prompt may not be able to access 32-bit programs in the Program Files folder. The WOW64 subsystem redirects and installs 32-bit programs in the Program Files (x86) folder. To access the correct folder, you must change the command-line script. Alternatively, you must type the command-line script at a 32-bit command prompt. The 32-bit command prompt automatically redirects file system calls to the correct 32-bit directory.
Some 32-bit programs examine the version information of the operating system. Many 32-bit programs that perform this check don't recognize the x64-based versions of Windows as compatible operating systems. When this behavior occurs, the 32-bit program will generate a version check error, and then close. If this behavior occurs, contact the manufacturer of the 32-bit program for an update that is compatible with the x64-based versions of Windows.
The x64-based versions of Windows use the 64-bit version of Microsoft Management Console (MMC) to run various snap-ins. However, you may occasionally require the 32-bit version of MMC to run snap-ins in the WOW64 subsystem. For more information about the behavior of MMC on the x64-based versions Windows, see the "Running 32-bit and 64-bit Snap-ins in 64-bit Windows" topic in the Using MMC 2.0 section of the Microsoft Platform SDK documentation. To view this document, visit the following Microsoft Web site: Running 32-bit and 64-bit Snap-ins in 64-bit Windows
The x64-based versions of Windows support 32-bit instructions and 64-bit instructions. The WOW64 subsystem can run 32-bit programs in native 64-bit mode by switching the native mode of the processor. Separate hardware or software layers are not required. You may not experience decreased performance when you run a 32-bit program on the x64-based versions of Windows.

Hi,
I need to run the jboss server as a windows service. To achieve that i used Native JBoss. I am able to run it as a windows service using that but i can access jboss only on localhost. I need to run jboss on a specific ipadress. It can be done by few changes in the service.bat file.
This is the snippet of service.bat file:
:cmdStart
REM Executed on service start
call run.bat >run.log
goto cmdEnd
ipaddress has to be added in the service.bat file in the above code in the line: call run.bat >run.log
Similarly should i have to add the ipaddress even during shutdown in the code:
:cmdStop
REM Executed on service stop
call shutdown -S >shutdown.log
goto cmdEnd
I dont exactly remember how to add that ip address.
waiting for reply from someone.....!
Thanks in advance...
Regards,
Raghav.
