Microsoft Windows 7 Service Pack 1 64-bit Download

[Hebe Newnam]

Ihave 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?

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?

In case anybody runs across the same thing I did: I had created two new config settings (copied from the Debug config). For some reason "Prefer32Bit" flag was set to true, even though the checkbox was greyed out and unchecked in the project config page.

Though I didn't find such utility in .Net v4 folder, the setting applies to Net4 AnyCPU assemblies as well. This flag is saved in DWORD registry value Enable64Bit under the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework

I often use a starter application, where I explicitly compile the .exe as x64 or x86 and ship x86 and x86 versions of the .msi. This is probably the easiest route - The performance gain is generally worth the overhead of managing additional files.

Edit: I found out how to uninstall an existing service in my installer here:

I built theapplication and it runs fine in the Visual Studio web server, but itdidn't work in IIS -- it seemed that the threads I launched to processthe engine events would die after a short while. I rewrote theapplication to put the TS Engine into a Windows Service. This worksfine in WinXP (32-bit). The service works in Visual Studio'sWfcSvcHost (a test client) on Windows 2K3 (64-bit), but doesn't workwhen installed as a Windows Service in 2K3 (64-bit). The TestStandengine code just hangs at the constructor for the TS Engine ... itdoesn't crash, no exceptions are thrown, and if I stop it with thedebugger, the thread is in the constructor.

I'm not sure about the service problem, but if it's possible to create your own threads in IIS you might be able to workaround the problem you were seeing there by creating your own thread that then creates the teststand engine, that way you can control the lifetime of the thread.

Also, the TestStand engine expects the thread that creates it to be the one that will process window messages for dispatching UIMessages, so for things to work correctly you will need a message loop running in that thread at some point after creating the engine.

How does one control the lifetime of threads in IIS? When I tried in IIS my threads were dying unpredictably and I decided that maybe this was a normal behaviour for a web server .. who would normally want processes to outlive the duration of a request? (I say ironically, because I do!)

With regards to your second comment, I discovered this also. Though what I find weird is that the engine only seems to run during my calls to execution.WaitForEnd(...) ... I couldn't find any other method that tells the engine to do work. So I wind up calling WaitForEnd(....) on executions I know to be already complete (when I have no active executions) in order to "run" the engine. Is there so other method I'm missing?

I don't really know anything about IIS so I'm not really sure what is best, but if you keep running code in a IIS thread and never return from it until your application is done then the thread will likely be around at least as long as your code is running. The code you should be running is likely a message loop, which is related to the other issue you are asking about, about the engine running.

The other issue you are asking about, about the engine running, is that you need to have a message loop in your main thread (the one that creates the engine) in order for the UIMessages to be processed (i.e. for the engine to run). Typically, programs which display windows have code which does this for you whenever your application is idle. If your program does not really have a UI, then you might need to implement the message loop yourself. In C a Windows message loop looks something like the following:

Ideally, the thread that creates the engine should be doing Window message processing whenever it is idle until the application exits (Typically until a WM_QUIT message is sent at which point GetMessage will return FALSE thus exiting the loop, or you can create your own mechanism for telling the main thread when to exit the loop).

Thanks. Though of course this doesn't solve my win2k3x64 problem, it does make my message pumping much cleaner. I used your advice to generate the code below. It isn't a loop itself, but I already had a loop -- just no mechanism to pump windows messages. Now I do! (Thanks again!)

Glad the message processing information was useful. I think to fix the issues you have with doing things from a server you need to create and own the thread that you create the teststand engine in and have a message processing loop in that thread (it will also be the thread than the UIMessage event callback is called in). That thread should just never return until you are done with the teststand engine (you can use some sort of inter-thread communication to tell it when to exit). I'm really not sure what you are currently doing though. Perhaps if you explain it in more detail, like what threads exist, how your code is being run, how the engine is being shared between threads, etc. I might be able to suggest a better solution.

My problem is WCF in Windows Service on Win 2K3-64... my thread just disappears into the constructor for the Engine ... never comes back. If I hadn't seen so many cases where it does work (on 2K3-64) I'd just let it go.

One thing that might be a factor is that on newer versions of Windows (at least on Vista so maybe they also do this on Windows server) it is no longer possible to run a service as interactive (i.e. an interactive service is one that displays windows). I think they do this for security reasons. Perhaps a messagebox is being displayed, but can't be shown because it is in the process of the service?

The issue is with the federated arcgis server, second machine. We have noticed that on panning, zooming webmaps in a desktop browser, is causing the arcgis server to slow down and eventually services don't respond. the windows service for arcgis server is terminated, while we see the arcsoc processes are still around, almost all of them,

Could you comment on whether or not RAM and CPU resources are meant to scale based on demand? Or are they static? If static, do they meet the minimum requirements as listed here: -requirements/latest/windows/arcgis-server-system-requirement...

So if my guess is right there are a few possible solutions, I have seen the arcgisserver.exe crash when the server has a lot of services 500 and the server has low clock speed around 2.4 GHz, in this case the solutions was the reduce all the pooling minimum instances to 0 -You can up the pooling for critical services- and that stabilized the system.

The Second case that I had was a ArcGIS Server that had over 1000 services it generated the low memory error that you mentioned even though it had more than enough swap memory, the solution is shared instances , but this only works for services published out of pro so you will have to convert any ArcMap Services.

If the Windows OS is reporting virtual memory exhaustion, that's usually a pretty reasonable diagnosis and is hopefully trivial to remedy. An important thing to keep in mind is that in the latest Windows Server operating systems (2016 and 2019), the page file growth is limited to the size of the volume it is on divided by eight. This means that for a 60GB C: volume, the default system-managed settings would restrict growth of the page file to 7.5GB.

With that in mind, you may want to work with your IT team to either define a static value for the page file (old-school recommendations range between 1.5-3x the amount of physical [or virtual] RAM on the machine), or move the page file to a volume with a larger size to allow for additional expansion of the virtual memory.

I don't know why the site is now throwing cert errors, try It is a popular way to convert exe's into windows services. You can download it from their site or search google and find an alternate location.

Running metabase using java is great, but what if you want to run it all the time. On windows you have the options of adding it to start up, but even then you will have to login to the machine to start metabase. So to convert it to something like a service, the best option is to run it as a windows service.

"Windows could not start the Metbase-Service service on Local Computer.

The service did not return an error. This could be an internal Windows error or an internal service error.

If the problem persists, contact your system administrator."

Problems may occur when trying to set up Crowd to run as a Windows service with JDK 1.6. The problem is caused by a failure to locate MSVCR71.DLL, which can be found in your %JAVA_HOME%/bin. There are two options to resolve this problem:

If you are running 64-bit Windows, please note that Apache Tomcat cannot run as a Windows service if you are using a 64-bit JDK. Please ensure that you are using a 32-bit JDK. This is the recommended solution.

Alternatively, you can install a 64-bit JDK and set JAVA_HOME to its location. Then follow the same steps above for Installing Crowd as a Windows Service. You'll need to replace CROWD_INSTALL\apache-tomcat-5.5.20\bin\tomcat.exe with one compiled for 64-bit from these locations:
