Cannot run QuickBooks Desktop Pro 2020 due to IE Internet Explorer 11 requirement

Hi Chris,

We've created a built-in browser to replace Internet Explorer 11. All you have to do is update your QuickBooks so it can be patched with the program. Since you can't open QuickBooks now, you'll want to manually download the update online and run it on your computer.

1. Go to the Downloads & Updates page and select the standard setup. 
2. From Select Country, select your country.
3. From Select Product, select your product.
4. From Select Version, select your version (year).
5. Select Search.
6. Select Get the latest updates.
7. When the download finishes, open the file to install the update. Restart your computer after installing it.

If you receive an error or the update fails to install, end the following background tasks and reinstall the downloaded update file afterward.

1. Close QuickBooks.
2. Right-click on the taskbar, then select Task Manager.
3. Under the details tab, look for the following background processes to select and End task for each.
   • QBW32.exe or QBW.exeQBCFMonitorService.exe
   • qbupdate.exe
   • QBDBMgr.exe or QBDBMgrN.exe
   • QBMapi32.exe
4. Right-click on the QuickBooks shortcut and select Run as administrator.

Here are the articles about the built-in browser and the manual update for your reference.
