Solution 1: Run the QuickBooks Install Diagnostic tool from the QuickBooks Tool Hub

Step 1: Download and install the QuickBooks Tool Hub

The QuickBooks Tool Hub helps fix common errors. You'll need to close QuickBooks to use the tool hub. For the best experience, we recommend you use Tool Hub on Windows 10, 64-bit.

1. Close QuickBooks.
2. Download the most recent version (1.6.0.5) of the QuickBooks Tool Hub. Save the file somewhere you can easily find it (like your Downloads folder or your Windows desktop). Note: If you've installed Tool Hub before, you can find out which version you have. Select the Home tab. The version will be on the bottom.
3. Open the file you downloaded (QuickBooksToolHub.exe).
4. Follow the on-screen steps to install and agree to the terms and conditions.
5. When the install finishes, double-click the icon on your Windows desktop to open the tool hub.

Note: If you can't find the icon, do a search in Windows for QuickBooks Tool Hub and select the program.

Step 2: From the Tool Hub, run the QuickBooks Install Diagnostic tool

The QuickBooks Install Diagnostic Tool automatically will diagnose and fix issues with Microsoft components the QuickBooks program uses.

1. Open the QuickBooks Tool Hub.
2. In the tools hub, select Installation Issues.
3. Select QuickBooks Install Diagnostic Tool. Let the tool run. It can take up to 20 minutes.
4. When the tool finishes, restart your computer and open QuickBooks.

If you can open and work in QuickBooks, everything is fixed.

If you still see Error 1904, move on to Solution 2.

Solution 2: Manually fix Windows components

If QBInstall and the update didn’t fix the error, you can repair specific Windows components yourself.

However, you should only do these troubleshooting steps if you’re an IT professional, confident Windows user, or working with the experts from Microsoft support.

• Repair or reinstall Microsoft .NET Framework
• Repair Microsoft MSXML

If you can install and open QuickBooks, you’re good to go. If you still see problems, move on to Solution 3.

Solution 3: Change your Windows account settings

Switch to the Windows Administrator account to change some settings.

Switch to your Windows Administrator account

1. Open the Windows Start menu.
2. Type “CMD” into the search. When you see the CMD Run icon, right-click it and then select Run as administrator.
3. Type “net user administrator /active:yes” in the command window and press Enter. When the command is complete, close the command window.
4. Open the Windows Start menu and select sign out.
5. Select the account that says Administrator and sign in. You won't need a password.

Change your user permissions

1. Open the Windows Start menu.
2. Type “File Explorer” into the search and open File Explorer.
3. Search for C:\Program Files\Common Files.
4. Right-click the Common Files folder, and then select Properties.
5. Go to the Security tab, and then select Edit.
6. In the “Group or user names” section, select Users.
7. In the “Permissions for Users” section, turn on the following permissions: Modify, Read & execute, List folder contents, Read, Write.
8. Select Apply and then OK.

Reinstall QuickBooks and sign out

1. Follow the steps for installing QuickBooks Desktop. This shouldn’t impact any existing company file data.
2. When the install is finished, open the Windows Start menu and sign out of the administrator account.
3. Sign in to your usual user account.
4. Open the Windows Start menu.
5. Type “CMD” into the search. When you see the CMD Run icon, right-click it and then select Run as administrator.
