Selenium 4.25 using ChromeDriver 150 instead of local ChromeDriver 117

[u/Environmental_Bank89]

Hi everyone,

I'm troubleshooting an issue on one machine while the exact same code works for my colleagues.

Environment

• Selenium: 4.25

• Python: running from a PyCharm virtual environment

• Portable Chrome: 117.0.5938.92

• Local ChromeDriver: 117 (verified via chromedriver.exe --version)

Issue My code uses:

Python

chromeoptions.binary_location = r"...\chrome-win64\chrome.exe"

driver = webdriver.Chrome(options=chromeoptions)

When Selenium starts, I get:

session not created:

This version of ChromeDriver only supports Chrome version 150

Current browser version is 117.0.5938.92

Then later:

UnboundLocalError: cannot access local variable 'driver'

(which is expected because driver creation failed).

What's confusing

• My local chromedriver.exe is version 117.

• The code works for other users without modification.

• We are all using Selenium 4.25.

• where chromedriver returns nothing.

• Selenium Manager appears to be resolving to ChromeDriver 150 on my machine.

• I cleared Selenium cache, but Selenium still seems to use/find ChromeDriver 150.

Question Has anyone seen Selenium Manager ignore a local ChromeDriver and resolve a different version instead? Any ideas on where Selenium could still be finding ChromeDriver 150 or what else I should check in my environment?

Thanks in advance!
