"System.InvalidOperationException" was thrown---error message


Recommended Posts

Hi, I am a cvitp volunteer and have done many taxes with auto fill.  Yesterday I tried doing a 2020 tax and got the error message "System.InvalidOperationException" was thrown.  I was able to do a 2022 file auto fill.  I looked up the error message on the board and none of the situations seem to apply to me.  I am using firefox browser but when I do auto fill it automatically pulls up edge browser. 

Does anyone have any idea of how to fix this?  Thanks, Yasmine

Hello yasdaz

UFile Windows - Auto-Fill Return (AFR) :
We have updated UFile 2018 to UFile 2020 (and was always included in 2021 and 2022) to use Microsoft EDGE which uses Edge WebView. (we no longer use Microsoft Internet Explorer 11).  Note that this also applies to the AFR for 2021 and 2022.
If you are receiving error messages, for AFR, relating to Internet Explorer (IE11) you should uninstall and reinstall your current versions of UFile 2018 to UFile 2020.
Download the latest versions here :
>>Previous Versions: 2021, 2020, 2019, 2018, 2017, 2016, 2015, 2014, 2013, 2012, 2011.   
Click on the year for the installation file required.
 You should also verify if Edge WebView  has been installed :
C:\Program Files (x86)\UFile 2020\DTWebViewApp\bin\Release
 If it is not installed then go here to download the installation:
Edge WebView installation from the official Microsoft website to download the installation file “MicrosoftEdgeWebview2Setup.exe”
Microsoft EDGE download :
