Method 3: Re-install the .NET Framework

If you’ve tried uninstalling the POS software and still encountered the 08W01 Quickbooks Point of sale error, then you can try uninstalling the .NET framework. Therefore, reinstall both the components.

To remove the .NET framework, try these steps:

With this action, you have removed it from your system. Now install the .NET 4.5 framework from the Microsoft store (4.0 client and extended).

Method 4: Create Windows User Account

You have to create a new account with administrator rights.

Here is how you’ll do it:

  1. Windows-> Start-> User Accounts (Search Bar)->Manage User Accounts -> Manage another account.
  2. Now click the Create a new account button.
  3. After that, rename this account.

Method 5: Uninstall QuickBooks Desktop POS

Another way to fix QuickBooks Error 100 is by reinstalling QuickBooks Desktop POS software. However, make sure to take a back of your data before uninstalling the POS software. Keep essential files with you and close the rest of the programs.

    • QuickBooks Point of Sale XX folder.
    • QBPOSDBSrvUser folder

    • After you’ve created and logged out of the user account, log in again. Then, open the POS and check if the QuickBooks Error 100 persists or not.

Method 6: Restart QBPOSShell

If you’ve tried closing and restarting QBPOSShell and found no success with QBPOSShell, then you can troubleshoot this error. For this:

  • Task Manager-> Processor-> Image Name-> Right-click QBPOSShell.exe file->End process-> Close Task Manager

This way, it will stop the POS software from running in the background. Then you can relaunch Point of Sale software.
