Hi, We are testing this line of code to launch Edge browser from our Javascript: var WshShell = new ActiveXObject("Shell.Application"); WshShell.ShellExecute('msedge', window.location.protocol + "//" + window.location.host + "/ebb/" + fileName, "", "open", 1); (protocol, host and fileName above are all runtime variables here and are all with correct values). This line works most times and Edge browser can be launched successfully. But in one of every four or five times, it won't do anything and no Edge browser can't be launced at all. Our Edge is "Version 121.0.2277.112 (Official build) (64-bit)" on Windows 10. Do you have anu suggestion what can be the cause? Thanks, Ligong

Hi @Zhu, Ligong , Thank you for your information. I have tested your code, but I can't reproduce this issue because it launches Microsoft Edge every time. This issue occurs in one of every four or five times, which sounds like something's wrong with the application itself. As a matter of fact, I suggest you repair Microsoft Edge in Control Panel --> Programs and Features --> Microsoft Edge --> Change. If repair does not fix this issue, I suggest you still use "iexplore.exe" for ShellExecute(), which is proved to work on your side. ================= UPDATE There're 2 ways if you still need to launch Microsoft Edge (IE mode) via JavaScript code: Add --user-data-dir=<path> command line for msedge (not iexplore.exe), but with a different <path> for each session. If you use IE mode site list policies, you can configure sites like this with the merge-type="no-merge" attribute: <site url="contoso.com"> <open-in merge-type="no-merge">IE11</open-in> </site> Then the site should be in its own unmerged IE session without modifying the JavaScript code. For more information, please read Does IE mode on Microsoft Edge support the 'no-merge' option that was supported in Internet Explorer 11?

UPDATE

There're 2 ways if you still need to launch Microsoft Edge (IE mode) via JavaScript code:

Add --user-data-dir=<path> command line for msedge (not iexplore.exe), but with a different <path> for each session.

If you use IE mode site list policies, you can configure sites like this with the merge-type="no-merge" attribute:

<site url="contoso.com">

<open-in merge-type="no-merge">IE11</open-in>

</site>

Then the site should be in its own unmerged IE session without modifying the JavaScript code.

Thank you very much for your help.

There is no easy way for us to repair or upgrade our Edge version.

Is it possible that you can try our code with the version I have and use '-noframemerging ' option when you launch your server for your url since that's what we do to make sure each IE (mode) session is not shared with others for our url.

Thanks.

Hi @Zhu, Ligong,

I have tested '-noframemerging', and it works for IE11, but it will not function the same for IE mode.

Do you have any other way in Javascript to launch Edge in IE mode and make sure it has its own session? We can't hardcode "iexplored.exe" any more. Thanks.

Thanks again for your help.

I believe our server uses "IE mode site list policies" you mentioned for our application to ensure unique session. I will appreciate if you can test our code again using this approach and see if you can launch Edge IE mode every time, or it may crash once every four or five times like we saw.

I added try/catch block to our code "WshShell.ShellExecute('msedge..." but it won't show any error message when it crashes from time to time.

Thanks.

Hi @Zhu, Ligong,

I have tested again with your code and also with the merge-type="no-merge" attribute. IE mode in Microsoft Edge is launched as expected every time. No crash was seen.

Did you test it with the Edge version we have or the one you have?

Hi @Zhu, Ligong,

I tested in the latest version. However, today I have tested in 121.0.2277.112, and Edge is correctly launched every time.

OK. Must be something wrong with our side. Thanks a lot.

Sorry one quick question, when you did your test, you didn't open a second (or more) Edge tab to open the url, is that correct?

We know that if there is an Edge tab open and we tried to access our url from another Edge tab, everything always works fine for us.

Sorry just want to make sure when your did your test, you used only one Edge tab, is that correct? As I mentioned before, when there is an existing Edge tab and we try to open a new tab to access our url, it always works fine. We only have the problem when we only use one tab.

Hi @Zhu, Ligong,

I have made sure there's no existing Edge process when I launch a new one, but unlike your scenario, every Edge tab creation attempt goes well here.
