System.IO.FileNotFoundException: Could not load file or assembly 'file:///C:\Windows\Microsoft.NET\Framework\v4.0.30319\-i

Question

I am trying to install a web service which is basically a file watcher service. But when I try to run this command Installutil –i "C:\\xxx\zzzz\ServiceTest.exe"

I get this error System.IO.FileNotFoundException: Could not load file or assembly 'file:///C:\Windows\Microsoft.NET\Framework\v4.0.30319\-i

I used to run this command before and I never got this error, I don't know what is different this time.

Try running

c:\Windows\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe -i "C:\xxx\zzzz\ServiceTest.exe"

The response you received doesn't make sense unless "installutil" has been redefined.

I get the same error if I download the windows10manager.exe (exe service sample) from the Internet. After I download the file, I go to file properties and I click in unblock button. After this operation, the service install successfuly. To automate this process, follow this thread: Unblock File from within .net 4 c#

Check the spelling of the service path specially the (") quote character write it and don't copy paste.

This works with me.

Change the compiler settings in Visual Studio from X86 to Any CPU or use the 64 bit InstalUtil inside "C:\Windows\Microsoft.NET\Framework64\v4.0.30319"

have you changed the compiler settings, recompiled the project and then tried to install it? try rebuilding the web service installer too – Razvan Trifan Nov 01 '12 at 12:18
Maybe some of your refereneced DLLs are still 32bit? You can check it with free tool depends.exe from Microsoft – Sebastian Xawery Wiśniowiecki Jun 11 '15 at 07:15

In my case, this error occur because the are some blank space in my project path e.g.: C:\user\Visual Studio 2019....

When I rename my path by deleting space, it worked fine

I had same problem, because the service name was only "Service.exe", so i change to C:\MyServices\NewService\Service.exe"

Wrong: C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\installutil /u Service.exe

Correct: C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\installutil /u "C:\MyServices\NewService\Service.exe"

works for me!

Can you explain further **what** you did? – Nico Haase Mar 06 '19 at 13:13
Did you actually meant to show *uninstalling* syntax? – Oak_3260548 Nov 01 '21 at 06:57
