Firefox 32 bit work, but 64 bit doesn't work

[tanaka1003 (tanaka-hiroaki)]

I tried open Firefox 32bit(ja) and 64bit(ja) using OpenBrowser on Windows 10(64bit).
each browser is latest version and added add-on.

32bit opened, but 64bit didn’t open and occured same error here:

Open browser : Cannot communicate with Internet Explorer browser

Hi, I am trying to use open browser activity in uipath , but it is giving the following error : Main has thrown an exception Message: Cannot communicate with Internet Explorer browser. Source: Open browser Exception Type: BrowserOperationException UiPath.Core.BrowserOperationException: Cannot communicate with Internet Explorer browser. —> System.Runtime.InteropServices.COMException: Cannot communicate with Internet Explorer browser. at UiPath.UiBrowserClass.Open(String bstrURL, UiBrowserF…

UiPath doesn’t support Firefox 64bit-version? Is there any official document about browser support ?

Seems the same issue as here:

Open browser : Cannot communicate with Mozilla Firefox

@Gabriel_Tatu yes, it is the current version of 50.1.0 However, I also just got it working. Now I’m using the 32Bit eng(british) version of Firefox I also tried 64Bit de, 64Bit eng(british), 64Bit eng(Us) and 32Bit eng(US), but for whatever reason they didn’t work either. For the record, I had this problem ever since updating a 32Bit de version.
