Hi All,

I’ve installed Acumatica multiple times, but I’m still encountering an HTTP 404 error when trying to access my local instance. Could someone please advise on how I can resolve this issue?

Hi ​@AKR2025, try to open/access it in Internet Information Services (IIS).

Confirm IIS site is running

Open IIS Manager

Go to Sites

Check your Acumatica site (ex: AcumaticaERP)

Make sure:

Status = Started

Application Pool = Started

If not, Start them.

 

Verify the URL + Virtual Directory

Most local URLs look like:

http://localhost/ERP

https://localhost/ERP

http://localhost:port/ERP

In IIS → Sites → your site, check if you actually have an app/virtual directory called:

 

Check if the Acumatica folder exists in the physical path

 

In IIS:

Right click your Acumatica site → Manage Website → Advanced Settings

Check Physical Path

Confirm the folder exists and contains:

web.config

Frames

App_Data

Bin

If those are missing → installation is incomplete.

Hi ​@AKR2025,

Please copy below highlighted URL and paste it into your browser. I believe the issue is related to your instance not having HTTPS configured in IIS.

You may need to access the site using HTTP instead of HTTPS, as suggested by ​@aiwan .

Thanks all for the reply.

Is there something wrong with our setup?

Hi ​@AKR2025,

I see you have added bindings for SSL. Have you tried your local site without SSL. Local instance does not need SSL, unless you have a specific requirement. Try removing binding and run your local site with the default settings. Also, try with just a http://localhost, does it give you a local IIS or errors out. If it errors, then there is some issue with your IIS installation. Let me know if above suggestions are helpful.
