The printer not activated – QuickBooks Error 20 is one thing which you might experience simply because that when you’re upgrading from or windows 7 or Vista to Windows 7, the latest operating system eliminates the employment of the HKEY_CURRENT_CONFIG\Software key within the registry settings. Which means that the entries found in that key are not updated when you’re upgrading the OS, plus some applications use that exact key to store internal settings, causing them to fail after an update.

This issue will likely appear if you’re a person who has upgraded his operating system to Windows 7 (a clear installation of Windows 7 won’t cause this), and you’re with the Quickbooks software. This might be one of many applications that uses the aforementioned key to store its internal settings, and simply because that the registry key is certainly not updated, the application won’t work properly.

There are two fairly easy methods that we can use to resolve this process, and we'll describe in both order to help you using this issue. Take note that these two methods will require one to have Administrator access to the device, otherwise they're going to fail.

NOTE: Before you make changes towards the Registry, make sure you take a backup of one's registry hive and create a method restore point incase something else goes wrong whilst you’re performing the steps you ought to be in a position to restore the device.

Create a Registry Backup
To take a Registry Backup, Once in the Registry Editor, click Computer from the top of the folder tree into the left pane and then Click File -> Export -> And Save It.

Create a System Restore Point
To generate a system restore point see steps (here). The restore guide is actually for Windows 10 however it works on Windows Vista / Seven and Eight as well.

Method 1: Reinstall Quickbooks

you upgrade the operating system, the settings for the app are lost, and reinstalling it will lead it to store its settings into the appropriate registry key again, and begin working again. You can download the application from here, after which it the installation is an easy process. When you’re done, you can continue being employed as before.

PRO TIP: If the issue is with your computer or a laptop/notebook you need to try using Reimage Plus that may scan the repositories and replace corrupt and missing files. This works in most cases, where in fact the issue is originated due to a system corruption.

Method 2: Manually update the registry key

Option 1: Grant Permissions via Registry Editor
In the event that you choose for this technique, please be mindful to adhere to each step of the process word after word, as an error might cause more headaches than the error itself. To start with, you need to open the Registry Editor. Press the beginning button on your own keyboard, and type regedit. DO NOT press Enter yet. When you get Regedit, right click about it and select Run as administrator. This can offer you an administrator use of the Registry Editor. What you’re looking for this is actually the HKEY_CURRENT_CONFIG folder, inside of that you will find an application folder. Right click the Software folder and select Permissions. When you look at the window that opens, make certain you have checked Full Control for the Users user in the table. When done, press OK to close the window, then close the Registry Editor. This may again give Quickbooks access to the main element it requires to store its settings, and everything will likely be working properly again.

Both methods are fairly easy, and if you’re having this problem with Quickbooks or any other software that uses that key to store settings, they will help you get rid for the problem, and you can continue your work as if nothing happened.

Option 2: Use a Powershell Script to Grant Permissions (Windows 10) only
The consumer account that needs permissions ought to be logged in and may be an administrator to execute the command. Head to Start -> type cmd and right click it, then choose Run As Administrator

Once within the Command Prompt, type powershell and press ENTER.

Then, type or copy the following command since it is:

PowerShell.exe -NoProfile -NoLogo -NonInteractive -Command “$key = [Microsoft.Win32.Registry]::CurrentConfig.OpenSubKey(‘Software’,[Microsoft.Win32.RegistryKeyPermissionCheck]::ReadWriteSubTree,[System.Security.AccessControl.RegistryRights]::ChangePermissions); $acl =$key.GetAccessControl(); $rule = New-Object System.Security.AccessControl.RegistryAccessRule (‘Users’,’FullControl’,’ObjectInherit,ContainerInherit’,’None’,’Allow’); $acl.SetAccessRule($rule); $key.SetAccessControl($acl);”
