"Error 1316. The specified account already exists." message when uninstalling Quickbooks Pro 2020

Hello there, @gnocchi.

I've got a couple of steps that you can follow to uninstall the QuickBooks Desktop to avoid receiving error 1316.

Since you've already used the QuickBooks Tool Hub, it doesn't fix the issue. I recommend removing it through the Control Panel, so you can uninstall it successfully without receiving an error. Here's how:

1. Open the Windows Start menu, then search and open the Control Panel.
2. Select Programs and Features or Uninstall a Program.
3. From the list of programs, select the version of QuickBooks Desktop you want to remove.
4. Select Uninstall/Change, Remove, and then Next.  

Another option that you can do is to uninstall the software and rename the installation folder manually. You can refer to this article for more details about this process: Clean install QuickBooks Desktop.

If it still doesn't fix the issue and you can't uninstall it, I'll include this link to resolve problems that block programs from being removed or installed on your device. 

In case you want to reinstall QuickBooks Desktop, you can download and install it again on your computer to manage your accounts and business.

Thank you @JuliaMikkaelaQ 

Happy New Year to you and your team. 

Unfortunately, the same Error 1316 message always shows up upon uninstalling QB. The software

then rollsback any uninstallation tasks and I'm back to square one.

Therefore the step suggested to manually uninstall QB from one of your links is not working.

Looking forward to new suggestions.

Thanks,

Marty

Thanks for getting back with the Community, gnocchi.

Since you're unable to uninstall QuickBooks without encountering error 1316, I'd recommend getting in touch with our Customer Care team. They'll be able to pull up your account in a secure environment, conduct further research, and create an investigation ticket if necessary.

They can be reached while using QuickBooks.

Here's how:

1. In your top menu bar, go to Help, then QuickBooks Desktop Help.
   
   
    
2. Click Contact Us.
   
   
    
3. Enter a brief description of the issue in our Ask a question (or tell us what's wrong) field, then hit Continue.
   
   
    
4. Select We’ll contact you for a callback or Message Us to start an instant messaging session.

Be sure to review their support hours so you'll know when agents are available. You can also contact them outside of product if necessary.

I'll be here to help if there's any additional questions. Have a lovely Tuesday!

Install the trial version of QB Desktop 2021 to isolate the problem.

Thank you for your help, 

Since I'm unable to run Quickbooks at all, I'm not able to perform the indicated tasks. 

In addition, even though I was able to uninstall Quickbooks Desktop Pro 2020 using a third-party tool, 

I'm still unable to reinstall it. I've gotten the following errors, even though I made sure that all .NET options in Windows features were turned on.

- Error 1712. One or more of the files required to restore your computer to its previous state could not be found. Restoration will not be possible. #when installing Quickbooks with new installer

- Error 1935. An error occurred during the installation of assembly Microsoft.VC90.ATL, version = 9.0.30729.1...

I'll reach out support and go from there. I do welcome any other tips you may have. 

Thanks,

Marty

Thank you for this @4Gal 

Could you please provide the actual link so I can download it? I was unable to find it.

Have a great day,

Marty

You can download the installer file from this source

https://downloads.quickbooks.com/app/qbdt/products

But you will need to contact me in private to get the trial code for QBD 2021 US Pro. Click on my profile name and you can find our website address to send emails.

Hello Again,

I followed all the .NET steps on this link after uninstalling my antivirus.

https://quickbooks.intuit.com/learn-support/en-us/help-article/install-products/manually-fix-microso...

I now get the following screen when using Quickbooks Desktop Pro 2020.

Apparently the Error code 1935 is due to .Net installation missing or corrupted. I reinstalled .Net from scratch and these are the .Net versions I have installed:

Currently installed "classic" .NET Versions in the system:
2.0.[removed] Service Pack 2
3.0.[removed] Service Pack 2
3.5.[removed] Service Pack 1
4.0.0.0
4.8.09032

What other .NET version do I need installed for a successful install?

Thanks,

Marty

Thanks for joining this thread, @gnocchi.

Let me share info about the error code 1935 when installing QuickBooks or Microsoft .NET Framework .NET Framework and help you fix it.

When installing it sometimes you can receive Error 1935: This setup requires .NET Framework or Error 1935: An error occurred during the installation of assembly. 

There are possible reasons why you get reasons. These are: 

• Microsoft .NET Framework system files are in use by another installation.
• Anti-virus/anti-spyware applications are preventing installation.
• .NET Framework is not installed, damaged, or a program is preventing the installation.

To fix this, you don't need to install another version of QuickBooks or Microsoft .NET Framework .NET. We'll just need to perform the recommended solutions of Intuit. Here's how: 

1. Reboot your computer. And start the installation again.
2. If you have anti-virus or anti-spyware software, stop or temporarily disable it. And start the installation again.
   • If installation is successful, restart your anti-virus software.
   • If the error occurs again, proceed with the next step.
3. See Install QuickBooks in Selective Startup for detailed instructions.
4. If you continue to receive the error, see repair or reinstall Microsoft .NET Framework. And start the installation again.
