We had been running a e2e_appmon on Win7 workstation. However, recently we started moving them to Windows 10 and though setting-wise both machines look identical to me 
The same script on Win10 is not able to start the browser, it runs well when run through nimrecorder, but does not run when done through the probe.

- WTBho class (32bit) needed to be enabled

Release : 9.2.0

Component : UIM - E2E_APPMON 2.52

Enabling the WTBho class (32bit) allowed the test to execute and the browser to start for tests as well.

IE 11 should work fine as long as you review and follow the requirements, so please refer to this link and the comments regarding WTBho.
