FIXED: “Application SID Does Not Match Conductor SID…”

If you are trying to run an application on Windows 10 and you encounter an error message that says “Application SID Does Not Match Conductor SID…”, you are not alone. This is a common error that affects many users, especially those who have upgraded from previous versions of Windows. In this article, we will explain what this error means, what causes it, what impact it has, and how to fix it.

Understanding Application SID Does Not Match Conductor SID…

SID stands for Security Identifier, which is a unique identifier that Windows assigns to every user account, group, and object on the system. Every SID consists of a domain identifier, a relative identifier, and a set of sub-authorities. The SID of an application is the SID of the user account that installed the application. The SID of a conductor is the SID of the user account that is currently logged in and trying to run the application.

Causes of the Error “Application SID Does Not Match Conductor SID..”

The error “Application SID Does Not Match Conductor SID…” occurs when there is a mismatch between the SID of the application and the SID of the conductor. This means that the application was installed by a different user account than the one that is trying to run it. This can happen for various reasons, such as:

  • The application was installed by an administrator account, but the user is trying to run it with a standard account.
  • The application was installed by a local account, but the user is trying to run it with a Microsoft account, or vice versa.
  • The application was installed by a user account that has been deleted, renamed, or disabled.
  • The application was installed by a user account that has been migrated from a previous version of Windows, but the SID has changed due to a different domain or sub-authority.

Impact of the Error “Application SID Does Not Match Conductor SID…”

The impact of the error “Application SID Does Not Match Conductor SID…” depends on the type and function of the application. Some applications may not run at all, while others may run with limited functionality or performance. Some applications may also cause security or compatibility issues, such as:

  • The application may not be able to access or modify certain files, folders, or registry entries that belong to the original user account that installed it.
  • The application may not be able to communicate or interact with other applications or services that rely on the same SID.
  • The application may not be able to receive or install updates or patches that are specific to the original user account that installed it.
  • The application may not be able to use certain features or settings that are dependent on the user profile or preferences of the original user account that installed it.
