Quickbooks Installation Error: Access Denied

I was instructed by Support to uninstall QB and re-install it, then got cutoff from the call.  Hope I can find help here.   After uninstalling, then downloading QB Pro 2018, I attempt to install.  Upon doing so, I am asked if I want to replace some files.  I say Yes to All.  I then get "Access is Denied" to:




I click OK and installation proceeds.  I choose Express installation and I get a Intuit Quickbooks Desktop Installer window with an error message.  A screenshot is attached.  It says,


ERROR Installing


MSI Returned 1622: Error opening installation log file. Verify that the specified log file location exists and that you can write to it.

Last System Error. Class does not exist.


BTW, I tried doing what is suggested here,,

which refers me to this,

"fixing" .NET Framework did not solve the problem

 Good work for doing the steps from those articles, Kar1o.


I have another article that will help you fix QuickBooks Desktop install errors. It has 5 solutions to help you resolve your concern.


Although, if you're still encountering the same issue after trying those steps, I'd suggest reaching out to our customer care support. I know you've called in before. However, a phone or chat agent has more tools that can help you fix it. Here's how:

  1. Open this link.
  2. Select QuickBooks Desktop.
  3. Click Continue as guest, then select your Desktop version.
  4. On the Contact Us page, select Quickbooks Setup & Navigation, then click Installing QuickBooks.
  5. Select either Get Phone Number or Start a Message.

Feel free to post anytime in the Community if you have other concerns. We're just around to assist you.

Thanks for suggestions.  We were on the phone with Support again today.  After fiddling with a few things, an Error Code 1622 came up during installation.   Installation was finally accomplished by doing it from a newly created Admin account

I would like to solve the Error 1622 problem.  The original admin account has no problem installing other programs.  This is a QB-only issue.  How to solve the problem?

I ask because there continues to be a problem even after installation.  The new admin account, from which installation succeeded, and other User accounts have no problem opening QB.  The original admin account, in which 1622 occurs when attempting to install, cannot successfully open QB.  The QB opening screen flashes then it shuts down.  The only way for the original admin account to open QB is to delete EntitlementDataStore.ecml in ProgramData/Intuit/Entitlement Client/v8.  Support says it is a "known" issue and is being investigated.  But, I am guessing that fixing whatever is causing the 1622 error at installation move me towards fixing the other things.

Hi there, kar1o.


I've also looked into the links you shared, and I can see that they are helpful for this scenario. Deleting the ECML file is also a way to troubleshoot this issue.


It would be best if you can get in touch with our phone support again, so they can continue helping from where you left. They have more tools to check this further for you.


If you have questions aside from this, you can always go back to this thread.

Thanks. I was talking to a Level 2 Phone Support.  He was the one that helped me get QB installed using a new admin account.  He was the one who got QB exporting to Excel again.  He told me he was unable to resolve opening QB without deleting the ECML file. So, I need to find someone that can help with that.

Welcome to Community @kar1o,


I recommend not to delete the ECML file since this file is connected between your license and your QuickBooks account. However, you can run QuickBooks Tool Hub in your computer to fix your QuickBooks software.


First, you'll need to download QuickBooks Tool Hub, let me walk you through how:


  1. Close QuickBooks.
  2. Download the QuickBooks Tool Hub file. Save the file somewhere you can easily find it.
  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.

Once done, you can refer to this link for the steps on how to use QuickBooks Tool Hub: QuickBooks Desktop doesn't start or won't open.
