Can't open IE in Private Mode

I need to run katalon tests in IE private mode. I’ve added the following IE desired capabilities properties but it does not open IE in private mode.
InternetExplorerDriver.FORCE_CREATE_PROCESS - true
InternetExplorerDriver.IE_SWITCHES -private

Can anyone please help??

Hello,

I’ve done some poking around on this and have a bit of info that might get you in another direction to investigate.

I have entered in these settings and got more of an interesting response instead of IE just opening in the regular browser mode:

Its has given me the following error:
"Unexpected error launching Internet Explorer. Unable to use CreateProcess() API. To use CreateProcess() with Internet Explorer 8 or higher, the value of registry setting in HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\TabProcGrowth must be ‘0’"

However it looks like this is either hidden or inaccessible within my registry (might be some sort of restraint since this is a company terminal). Perhaps try the configuration I have set above and see what you get? You may have better luck than me.

Let me know what you discover!
