Aras Innovator 2025 Installation Error - HTTP 500 on IIS

Hello,

I am trying to install Aras Innovator 2025 on Windows 10 with the following configuration:

• SQL Server 2022 Express (HOURANI\TEW_SQLEXPRESS)
• IIS 10
• ASP.NET 4.8

The installation wizard completed successfully, but when I try to access the application at http://localhost/InnovatorServer/Client/index.aspx I get HTTP Error 500.

What I have done so far:

• SQL Server authentication is enabled
• Database InnovatorSolutions created successfully
• Users innovator and innovator_regular created with correct permissions
• InnovatorServer application added manually in IIS
• ASP.NET 4.8 enabled in Windows Features
• ASP.NET Core Hosting Bundle installed

Question: What could cause HTTP 500 after a successful installation? Is there a specific IIS configuration needed for Aras Innovator 2025?

Thank you!
