Hello, I’ve recently ran into an issue when working with selectors in Excel. Previously, I was able to use the web recorder and and modify the selectors and the automation would run fine. Now when trying to work with a check box selector in Excel, I receive this pop up error – “Error HRESULT E_FAIL has been returned from a call to a COM component”

This was just working a week ago. Any assistance is appreciated.

Also dealing with this same issue and would like some insight. ‘Click’ and ‘Check/Uncheck’ activities are no longer working for filter lists on Excel when they were previously and trying to select them as a target brings up this error message. Due to the nature of my process having extensive and variable filter lists, I cant use ‘Keyboard Shortcut’ activities in place of ‘Click’ activities either (which is the given workaround for this error).

It definitely seems like something has changed within UiPath Studio for this to suddenly stop working, when it was working perfectly fine just a couple of weeks ago.

Any advice or looking into this would be greatly appreciated.

This solved my problem:

Start —> Run —> regsvr32 %SystemRoot%\System32\msxml3.dll

Start —> Run —> regsvr32 %SystemRoot%\SysWOW64\msxml3.dll

Perhaps combining these two solutions did the job!
