Taxonomy Manager Blank


I recently downloaded the packages to test the Receipt and Invoice AI functionality but whenever I try to use the Taxonomy Manager it comes up blank. To close the application I have to Ctrl+Alt+Delete then the message “Communication between UiPat Studio and the Taxonomy Manager ended unexpectedly” appears. I am using the Community Version of UiPath.

Could someone please help me fix this issue? I would truly appreciate it.

Hi @shauny
Maybe you need to elaborate your issue try to put some screenshot or your xaml files to easily adress the. Issue thanks

Happy learning

Sure, I have attached the Taxonomy Manager blank page error. I am testing the receipt and invoice AI so there is no xaml file to attach as I got stuck at the Taxonomy Manager set up.

Hope that helps.


Any solution ?

Guys we also facing the same issue but if you open studio via admin rights it’s working but Non-admin account it’s not working.

Any buddy please provide the solution for this case.

It was a security issue on my end so I had the IT dept. perform the necessary firewall updates.

Has the firewall updates changes working fine ?

Hi Uipath Team,

Can you please help this issue.

Hello all,

Any chance you could share:

  • a full project
  • Studio version
  • Windows version
  • user account settings and permissions
    as we would like to see if we can reproduce it.

Also, can you reproduce this issue on a different computer?

Can you also try to open this project here How to use the IntelligentOCR Package and see if it works?

Check this package: image It is responsible for this issue.

Hi @shauncy what kind of firewall updates do we need to perform?
Running into same issue on my side.

Here are the steps we took. Hopefully it helps you:

  • Run program and record time of failure
  • Open event viewer:
    • Command prompt → eventvwr → enter
  • Browse to Applications and Services\Microsoft\Windows\AppLocker\EXE and DLL
  • Locate a red error with the timestamp around the time when it failed to launch. This will identify what’s been blocked.
  • Copy the filepath in the general section - should be an .exe program which is the problematic file
  • Send to IT Dept to add to action from their side

Hello everyone, I have the exact same problem on the “DELL inspiron 7506 2n1” while it works on the Microsoft pro surface. I need to fix this problem on my Dell. Does anyone see a solution to this.
Thank you in advance.

I’m having the same issue on a Dell Latitude 7420.

Windows 10 Pro v 20H2
Studio Pro 2021.4.3

Project is the DocumentUnderstandingFrameworkTemplate from the zip package.
Running as Admin didn’t work. No entries in the mentioned EventViewer path.

I upgraded the packages from the default template to get UiPath.CefSharpBundle from 1.3.0 to 1.4.0 - no luck.

Package works fine on a co-workers laptop. The project also works fine on my personal desktop.

This issue is happening for Enterprise Edition Studio 2020.10.4 . But working fine in community edition.

Having same issue - Taxanomy is blank and not working in DELL & HP 14 inch touch screen laptops -

Temporary Fix - If you want still this to work, just change the size of “Taxanomy manager” and keep performing your steps [it looks that you are not able to write and click but when you change the size your committed operation will performed]but what you need you have to change size after every steps you performed.

*** UI Path please resolve this ***
