IIS Express will not start

I'm just putting this one out there since its a Google Zero-resulter which means I win a prize?

Cannot start IIS Express 7.5 after reinstall from one account, but I can when logged-in under my other domain account.

What's odd is that the account it fails under is my 'super' account with local admin rights, and is also the account I installed it under.

The error stems from diprestr.dll not loading...

C:\Program Files (x86)\IIS Express>iisexpress.exe /trace:error
Starting IIS Express ...
Initializing the W3 Server Started CTC = 2068729
W3 Server initializing WinSock.  CTC = 2068744

Process Model Shutdown called
Failed to start 'HostedWASStart'.  Error = 38246848
HostableWebCore activation failed.
Unable to start iisexpress.

The specified module could not be found.
For more information about the error, run iisexpress.exe with the tracing switch enabled (/trace:error).

Any got any ideas? I'll try Process Monitor and see.

So far, IIS Express is proving to be just another thing to learn and go wrong.

Using JetBrains Rider, I had to remove this config file and that worked:

\.idea\config\applicationhost.config

I think this was caused when I removed VS.

On another occasion, I did get this issue due to custom HOST name and that along with some other PORT binding issues was resolved by running Rider as admin.

I had installed the Asp.Net Core Module / AspNetCoreModuleV2, which got added to my applicationhost.config like this:

<add name="AspNetCoreModuleV2" image="C:\Program Files\IIS\Asp.Net Core Module\V2\aspnetcorev2.dll" />

This caused the following startup trace:

Starting IIS Express ...
Initializing the W3 Server Started CTC = 105458609
W3 Server initializing WinSock.  CTC = 105458625
W3 Server WinSock initialized.  CTC = 105458625
W3 Server ThreadPool initialized (ipm has signalled).  CTC = 105458625
Failed processing with hr = 800700c1
Error loading global modules.  hr = 800700c1

Error loading global modules.  hr = 800700c1

After removing the line above, this issue went away.

Posting a linkback here + some more detail on Rider since this answer is the first that comes up in Google

This happened for me when launching a project in Rider which was working in VS 2019

This can happen if the bitness of IISExpress is incorrectly set -> your x86 program files folder instead of the 64bit program files folder

enter image description here

I has 2 things to do to make it work

  1. try as everybody do

    1.1. Delete all files in C:\{users}\My Documents\IIS Express\config
    (Note: Don't worry it will re-create it automatically, if you afraid you can copy to some other place first)

  1. If it still not work, try this below

    2.1. Delete all files in {your project}\.vs\{your project}\config
    (Note: .vs\ folder is hidden make sure you show hidden folder first)

    2.2. in Visual Studio > Right click on your Project > select Properties

    2.3. Select "Web" Tab > in Project URL > change your port (Example: change from http://localhost:1096/ to http://localhost:1097/)

    2.4. Save and run your Project again.

Only Deleting config folder did not work for me. Also i did this

"Delete the following file <>.vs\config\applicationhost.config, the .vs folder may be hidden"

To clarify John's comment - the directory will be something like C:\users\jmitchell\My Documents\IISExpress\config. I assume John is correct in that if it doesn't exist you would need to create the directory.

Alternatively the directory could already exist and just be corrupted. This is what I believe happened in my case. I had previously installed WebMatrix but ran into all sorts of issues today. After uninstalling IIS Express, Web Platform Installer, WebMatrix, and some SQL Server Management Objects, and then reinstalling WPI & WebMatrix, I came across this post.

I actually got IIS Express to run successfully after deleting the config directory mentioned above, and then re-running C:\Program Files (x86)\IIS Express>iisexpress.exe /trace:error

And I ONLY wasted two hours of my day on this! Thanks Microsoft!

I got this problem after upgrading to Web Platform Installer 5.

The quick fix for me was to also upgrade to Webmatrix 3 (http://www.microsoft.com/web/webmatrix/)

Also, you might need to change the line 

applicationDefaults applicationPool="Clr4IntegratedAppPool"

to 

applicationDefaults applicationPool="Clr2IntegratedAppPool"

in the file...

C:\users\jmitchell\My Documents\IISExpress\config\applicationhost.config

if you continue to get the same error (as I did) after following the instructions on the post above. The issue being solved here is that you don't have .NET4 installed, and so are reverting to using .NET2

Thanks

Check that the user its failing has a IISExpress\config folder in their home folder. If not then copy it over from the user where IISExpress is working. This is a common fault when the config files/folders are missing.
