I have created a very simple window service using visual studio 2010 and .NُET 4.0.

This service has no functionality added from the default windows service project, other than an installer has been added.

If I run "installutil.exe appName.exe" on my dev box or other windows 2008 R2 machines in our domain the windows service installs without issue.

When I try to do this same thing on our customer site, it fails to install with the following error.

Microsoft (R) .NET Framework Installation utility Version 4.0.30319.1
Copyright (c) Microsoft Corporation.  All rights reserved.

Exception occurred while initializing the installation:
System.IO.FileLoadException: Could not load file or assembly 'file:///C:\TestService\WindowsService1.exe' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515).

This solution has only 1 project and no dependencies added.

I have tried it on multiple machines in our environment and two in our customers. The machines are all windows 2008 R2, both fresh installs. One machine has just .net 2.0 and .net 4.0. The other .net 2, 3, 3.5 and 4.

I am a local admin on each of the machines.

I have also tried the 64bit installer but get the following error, so I think the 32 bit one is the one to use. System.BadImageFormatException

Any guidance would be appreciated. Thanks.

Another reason for this error might be that you copied your program from a source which windows considers untrusted. You can unblock the assembly by clicking "unblock" after you right-click and select properties on the file.

    This worked for me and answers the question more directly than the, "try a Setup Project" answer. Both work, but this is more likely the answer to the original question. – MKing Mar 21 '11 at 20:12

    If it won't unblock and it resides in your /Program Files folder then move the .exe to your documents folder, unblock it there, and then move it back. Windows Explorer won't elevate unblock requests in the /Program Files folders. – Snives Feb 16 '12 at 22:31

    Another useful advice: If you unblock a zip file before extraction, then all extracted files are automatically unblocked. Can save you a lot of work of unblocking them one by one :) – doublehelix Dec 04 '12 at 09:40

    Remember and unblock any associated DLLs as well as the main exe folks – Alan Macdonald Jan 08 '14 at 10:47
  • Unblocking the individual files didn't work for me. I had to unblock the zip file I downloaded them in. – cja Oct 09 '14 at 11:54
  • Just in case somebody needs to do this and have lot of dlls and exe as dependency, you can use powershell command `Get-ChildItem | Unblock-File` in the directory where service executables are. It'll unblock all files. – Rumit Parakhiya Apr 05 '16 at 09:50

    has MS fixed their error message yet? Is anyone aware of an MS ticket open for this? The error message gives you no indication of how to fix the problem. – Mike W Apr 20 '17 at 16:21

Need to unblock files. or at least that's what fixed mine.

To do 'bulk' unblock in Powershell

get-childitem *.* | Unblock-File 

or in DOS:

FOR %a in (*.*) do (echo.>%a:Zone.Identifier)

  • Or simply `get-childitem "C:\MyFolder" | unblock-file` – Peet Brits Feb 23 '17 at 10:46
  • If the files are being transferred to another machine, another easy way to unblock them all at once is to zip up the files, copy over the zip file, unblock the zip file, then extract it. The extracted files will also be unblocked. – cdhowie Feb 14 '18 at 21:24

When we copy executable from another computer, Windows mark a flag on them for protection. Right Click on executable and in properties Click Unblock. It would clear flag and service executable would Install.

This issue came about for me because I was trying to install the service from a network location. By copying the service.exe to the local machine prior to using installutil, it fixed my problem and the service installed successfully.

    Based on question http://stackoverflow.com/questions/8524423/could-not-load-file-or-assembly-hresult-0x80131515-when-adding-controller-to-m One could also set the runtime `loadFromRemoteSources` element to true in the machine.config. – Joshua Drake Aug 06 '12 at 19:09
  • I had to go to the properties of every file and "Unblock" the file. – Trevor Daniel Aug 25 '16 at 09:02

don't forget to vote up... Try the SC as follows: 1. open command line 2. write the below- sc create ServiceName BinPath= "ExePath". report on results...

In my case this error was caused by accidentally passing the directory containing the service to InstallUtil instead of passing the service exe.

Obviously human error but I found the error message quite misleading.

you can use this command in developer command prompt run administrator

installutil C:\...\MyService\bin\Debug\MyService.exe

I also faced the same issue. In my case I was deploying new version of utilities , i copied new exe , installog files and then trying to uninstall the utils.

I copied back the old version , uninstal the utils , copied the new version and installed it again. Anyway it is the logical sequence I should have followed in first place.

As per @doublehelix's response above, this answer put me on track for my particular issue which related to a service issue running in Windows XP (Unblock is not an option in the security tab that I could find). In my case I was attempting to run a service from a separate drive (i.e. not on the same drive as Windows and not under program files) although the actual physical disk was the same. Moving my service into the Program Files folder solved my underlying issue. (I intended to 'comment' against @doublehelix's answer but I don't seem to be able to in my current status).

Simply right click on your service files and select properties and then check the unblock checkbox

Unblocking files did the job here. Weird thing is that the blocked files came from a signed installer run with admin privileges. Had to unblock several files in several folders at once.

I used the following registry tweaks to add context menus to a folder or file when Shift + right-click is pressed (it doesn't show up if just right-clicked).

Folder tweak:

Just save it as ShiftUnblockFolder.reg and import into Registry.

You can try to make a Setup Project for your service and run the MSI file on that server.
