Open Browser: Cannot communicate with IE

When i’m trying to open any website using open browser activity, it is throwing an error (’" cannot communicate with IE "). I have seen previous solutions to this problem in forum and tried, BUT the issue is not solved.

Hi there bhargav29494,
Firstly, can you confirm you have IE selected in the properties tab of your Open Browser Activity:

In addition, can you ensure you have IE turned on from within Windows Features.



Hi @bhargav29494,

I already had this problem before and after reinstalling IE, it started to work again with UIPath.

Hello @dhinesh110,
I got this problem earlier, but unfortunately i’am not able to solve this. So I used ‘Open Application’ instead of ‘Open Browser’ activity which is working fine. So I suggest, if possible try with ‘Open Application’ activity.

Hi @bhargav29494,

  1. Open Command Prompt with Administrative Privileges.
  2. Type Command: Regsvr32 OLEACC.dll.
  3. Hit Enter and you are ready to go.

Let me know.


Well @jiban sometimes it also does not fix the problem for me… It should be check @badita @Teodor_Hoaghea


Hi @jibanjyoti,
I tried that process for many times. For me it didn’t worked. so I tried with open application activity. Should be check if there is any other process.

Hi @aksh1yadav and @bhargav29494 This solution should work. I tried many times with different users.
Anyways lets wait for @badita. Your opinion is required. :slight_smile:
Please tell us the alternative solution for this.

Dude i have tried even more and it was but you never know when things will start falling :stuck_out_tongue:

I have experienced it many recently even-though i have tested workaround but still i m eager to listen from their side :slight_smile:


So what is your suggestion? @aksh1yadav :slight_smile:

I don’t know. OS version? ServicePack?

As a workaround, though I don’t like to recommend this, have you tried Chrome?

Thank you!! Its working fine…

I use in XAML file open browser activity set as chrome but it was run in the “chromium” why?

And throws an error too ?
