Guys,

I think the issue is happening because the signature of the webconnector.exe itself is expired, so if you replace the webconnectore.exe with the correct version that matches your QuickBooks version, the case will be resolved.

Check the instructions in the link below. Works for us.
How to fix the error QuickBooks - Application with Revoked Certificate (intuit.com)

I managed to get it to work.  I have ZERO I.T. experience, but i did it!  At first it didn't work, because I wasn't on the ADMIN side of Quickbooks.  You have to be logged into that one, to grant the permission.  I'm so thankful this worked.  This really stressed me out.  I've seen others having more important reasons to get this up and running (like payroll etc) so I hope they too can get this up and running asap. Good luck everyone!! 

Did all these steps.

https://quickbooks.intuit.com/learn-support/en-us/help-article/web-integration/fix-error-quickbooks-...

The certificate is now valid, but this webconnector app does not open at all.  Double clicking on it does absolutely nothing.

This did not fix it for me.

That likely means you don't have the fixed webconnector.

https://quickbooks.intuit.com/learn-support/en-us/help-article/web-integration/fix-error-quickbooks-...

The fixed webconnector.exe DOES has a valid certificate.  Our problem is that this program doesn't start at all.

I am getting same thing.  Replaced web connector file as per instructions.  Web connector will not even launch now.

What is the error? Did you try to run the webConnector as Admin?

Also, you can check the Windows event viewer for both application and system for extra error log on execution 

We have run the fix.  Still getting the error message.  I cannot run the webconnector as Admin because the program I link to only allows one user to connect and it is not set up as the admin.

There is no error message. It just doesn't run. Tried as admin, nothing.  Double click on the application, absolutely nothing happens. Normal behavior is that the program window should open.

Here's the Windows event log.  Anyway it looks like it's still NOT fixed on the Intuit side.

Your instructions on how to contact you and report that I am having the same issue appear to be for online versions.  Can you please post instructions for desktop versions.

Thanks

looks like the app can not open a file either because the file does not exist or there is no permission. Did you copy the file to the directory with the original WebConnector.exe? If yes, I would
1. Uninstall the application,
2. Then install the latest version of the web connector from 2.3.0.215 from https://static.developer.intuit.com/resources/quickbooksWebconnector/QBWebConnector2_3R0_00215.zip

3. Then, depending on the version of your QB, follow this How to fix the error QuickBooks - Application with Revoked Certificate (intuit.com)

After downloading the new exe file, Remember you need to copy the new webconnector.exe in either

• 64 bit Windows - C:\Program Files (x86)\Common Files\Intuit\QuickBooks\QBWebConnector\.
• 32 bit Windows - C:\Program Files\Common Files\Intuit\QuickBooks\QBWebConnector\QBWebConnector.exe.

I hope this can help you. We were there with a few of our clients using our warehouse application with QB and know how stressful this can be.

I just called Quickbooks and your technician said it was the 3rd party field service application's fault using an outdated certficate. He said it wasn't Quickbooks and couldn't help me. He then hung up on me. Who's fault is it? How do we correct - through the 3rd party or Quickbooks? I took all the steps in your "Quickbooks - Application with Revoked Certificate" and it isn't work. Please advise.

Thank you for reaching out to the Community for help with this issue, everyone.

We are here for you and want to help get you back to business quickly.

The issue usually occurs because the QuickBooks Web Connector digital certificate has expired. Not to worry, I've listed the steps below to resolve this:

1. Update all versions of QuickBooks Desktop to the latest release.
2. Select the your version to download the QBWebConnector.exe. If you have more than one version installed, select the download for the latest version:
   • QuickBooks 2023 / Enterprise 23
   • QuickBooks 2022 / Enterprise 22 
   • QuickBooks 2021 / Enterprise 21
3. Close all versions of QuickBooks completely.
   • Press CTRL, ALT, and Delete on your keyboard simultaneously.
   • Select Task Manager.
   • Make sure QBW.exe, QBW32.exe, and QBWebconnector.exe aren't running.
4. Rename the QBWebConnector.exe:
   1. Press Windows + R on your keyboard.
   2. Enter the following: 
      • 64 bit Windows - C:\Program Files (x86)\Common Files\Intuit\QuickBooks\QBWebConnector\.
      • 32 bit Windows - C:\Program Files\Common Files\Intuit\QuickBooks\QBWebConnector\QBWebConnector.exe.
   3. Rename the QBWebConnector.ese to OLD_QBQWebConnector.exe.
5. Go to File and select Open New Window.
6. Open Downloads, then copy the QBWebConnector.exe you downloaded in Step 2 to the folder you used in Step 4.
7. Reopen QuickBooks Desktop and use Web Connector.

You can also visit our QuickBooks Status page to monitor the progress. There will also be an option to subscribe to get notifications automatically.

Additionally, I've added an article that'll help you review your bank transactions in QuickBooks Desktop to ensure you add them to the correct accounts: Add and Match Bank Feed Transactions. 

I appreciate all your patience in this matter. Please know that we're doing our best to resolve this issue. Keep us posted if you need help integrating applications or managing your books.

My IT people said that they did these steps.  It is still not working for any of our integrated applications.

What version should the WebConnector be if it is fully updated?

I did everything from the original corrections to uninstalling and reinstalling Web Connector but nothing works yet!!

I have tried the fix as well....does not work.  QB keeps saying they are working on it but still no fix.  Can someone from QB give us something other than "here is how  to tell us you are having a problem and we care about fixing it....but, we can't fix it"!!!!!!!

These steps do not work for me.  After completing these steps, the QBWebConnector.exe still doesn't work.  When I check the Windows Event Viewer in the Application folder, I see this error:

Did ALL that multiple times, very carefully.  The new version of webconnector V.240 does have a valid certificate.  But the executable FAILS TO RUN.  NOTHING happens when you try to run it.  I've posted the Windows event log earlier.  The issue is NOT resolved.

I finally got this resolved.  The most recent version of WebConnector on Quickbooks site is 2.3.0.215.

However, I had a folder on my computer with version 2.3.0.240.  I don't even know how that got there.  It must have been automatically updated.

But the new replacement version of QBWebConnector.exe only works with version 2.3.0.240.

Again, I don't even know where to get version 2.3.0.240, but that is required to make the new .exe file work.

I missed the last part of "COPY" Web Connector to the same folder you renamed it to OLD. Once we did that, then opened quickbooks and it asked for sync settings again and worked fine

Same issue.  Instructions in the Link do not work.

A.  Using the cut'n'paste  C:\Program Files (x86)\Common Files\Intuit\QuickBooks\QBWebConnector\ provided in the instructions doesn't work.  Couldn't find the application.  Went to the download folder as recommended by my 2nd QB tech support rep. Found QBWebConnector.exe.config but not QBWebConnector.exe.  Went to programs and followed the trail in the link, no such fiile.

B. In the instructions c.) uses the extension ese not exe - please proof read!!

Initially went to chat and was told to provide all this file information (some about needing payroll), gave them my info. told them I am a ProAdvisor and was told I wasn't authorized to work with the file??

The rep I spoke to when I called tried to walk me through updating but she agreed the file I found was not the correct one.  She said to try back at 5pm (LOL).  Meanwhile this is a client file and they need the sync information to do their job.

Seriously, why am I a ProAdvisor?

Doesn't work, same initial instructions.

Chat disconnected me.  Said my identity couldn't be verified after trying to sell me payroll!
