Quickbooks Has Reached the Maximum Number of Unregistered Users

Quickbooks Has Reached the Maximum Number of Unregistered Users

The QuickBooks software has reached the maximum number of unregistered users and has many other serious bugs that cause serious problems with the operation of your Windows system. This problem freezes all running windows and makes them unresponsive to all commands. This issue usually occurs when the number of boot entries exceeds the installer limit unnecessarily or when there is a registry error.

Learn all about how to fix this problem in this blog.

Whether used in a single-user mode or used in a multi-user mode, QuickBooks Programming adapts to both situations. While working on a multi-user mode, you would notice that you can add the respective clients much more easily and can get in touch with organization documents. 

However, in case you are getting an error message indicating that you have reached the maximum number of unregistered users, it immediately indicates that there may have been a mistake. Don’t be concerned in case you get this error message; there are many reasons for this issue to appear in your QuickBooks applications. This article will provide the steps involved in resolving the problem of having the maximum number of unregistered users.

What is the limit of QuickBooks users? 

QuickBooks is an accounting software that can be used in single-user and multi-user modes. For each mode, you need a license to use the same mode. When a user purchases a single-user license for QuickBooks, it allows one user to access QuickBooks from two different systems. When QuickBooks has a multi-user license, it allows QuickBooks to be used by multiple people, meaning more than one person can access QuickBooks. The maximum multi-use license is 30.

1. The Single User License:

A single-user license means that only one person can use QuickBooks on a single system at a time. Purchase two single-user licenses in case you have two users who need to share QuickBooks on the system. In case QuickBooks is installed or running on a single system and both users have their own single-user license, they can share QuickBooks installed on the same system. Both users can work independently, which means they can install QuickBooks on their own systems as well as share. They can keep their personal files or databases on their own system or on a shared system such as a server. QuickBooks lets both users work on the same program at the same time.

2. License for Multiple Users:

In case more than two people need to access QuickBooks on the same system at the same time, a multi-user license is required. A multi-user license allows a fixed number of users to use QuickBooks at the same time.

In QuickBooks, there are three kinds of multi-user license categories:

  • QuickBooks Pro: Maximum Three-User License
  • QuickBooks Premier: Maximum Five-User License
  • QuickBooks Enterprise: Maximum Five to thirty user License

3. User and License specifications:

Some specific users are assigned to both single and multi-user accounts. In case someone else wants to use the software, they can’t, because these users can’t be shared across the broad group of people who want to use the product. Each user has their own unique license; no one can share another’s, however in case an employee leaves the company, you can transfer his license to another user that works on that system.

4. QuickBooks Multi User:

When using multi-user QuickBooks, the QuickBooks database is linked to the same drive on which all the users are located, allowing the user to access the data from the same drive. Main system is the server that stores all the data, and everyone can access the data base from the server. In case you have a server, you do not need to purchase a separate license for your device.

Reasons for the maximum number of unregistered users:

You have exceeded the maximum number of users who can access the company at the same time. This error occurs because:

  • You have more seats available than purchased licenses.
  • The workstation must be rebooted because the log file hangs.
  • The file used to check licenses is corrupted.
  • Your QuickBooks Desktop POS installation is corrupted.
  • A third-party firewall or internet security is blocking access to the server from the client workstation.
