Though a quick test with IEDriverServer_Win32_3.9.0 doesn't shows any error. Though IEDriverServer_Win32_3.9.0 and IEDriverServer_x64_3.9.0 are put up but was never explicitly pushed/published to be available on the Download tab of seleniumhq.org page.

The CHANGELOG of IEDriverServer.exe clearly mentions the following disclaimer :

The "major" and "minor" fields are synchronized to releases of the Selenium
project. Changes in the "build" field indicate interim releases made publicly
available via the project downloads page. Changes in "revision" field indicate
private releases checked into the prebuilts directory of the source tree, but
not made generally available on the downloads page.

Additionally, the CHANGELOG of IEDriverServer.exe v3.9.0.1 mentions the following disclaimer :

Finally, there is every chance that, despite all efforts to the contrary,
it's possible that there are new regressions introduced by this change.
Multiple test suites have been run using this change, and none have
failed thus far due to the changes herein. Claims that this change is
causing a specific failure should be accompanied by a full test case, or
issues reported against this change will be summarily closed.

Solution

The simple solution would be either to :

• Use IEDriverServer_Win32_3.9.0 on both 32bit and 64-bit platforms.
• Revert back to IEDriverServer_x64_3.8.0
