How to rollback selenium 3.0.0 to 2.53.1?

[nhtrader]

WinXP Pro SP3 (32bit)
Python v3.4.3
PIP 8.1.2
Selenium 3.0.0
Firefox v49.0.1
geckodriver.exe v 0.11.1

Yesterday I accidentally upgraded Selenium to v3.0.0, and of course it doesn't work on my ancient PC.
Yesterday I was using FF v47.0.1 & Selenium 2.53.1 and an older version of PIP(didn't take note of it). Everything worked fine. No Errors.

Today I'm stuck trying to undo my mistake and get Selenium 3.0.0 & FF v49.0.1 to work:
Error 1 - geckodriver.exe not found in PATH
      So I downloaded geckodriver v0.11.1.zip expanded it, and transferred geckodriver.exe to valid PATH (C:\Python34)

Error 2 - selenium.common.exceptions.WebDriverException:
       Message: Service geckodriver unexpectedly exited. Status code was: 3221225781

Question 1 - How can I fix Error 2?
Question 2 - How can I rollback to selenium v2.53.1 (also tried v2.53.0 - same error resulted)?

I can tell you that I tried to rollback doing the following, two different ways, but both failed.
Method 1 -
1. downloaded win32-selenium-2.53.1.zip (131Mb, not IE driver server version 1Mb) & expanded it.
2. opened command prompt and changed DIR to location of .\selenium-2.53.1\setup.py
3. ran command: python setup.py install - FAILED.
Output:

Method 2 - This was an attempt to use PIP to install my local copy of v2.53.1

I'm thinking if you're going to roll selenium back you wouldn't need to worry about the error.

Since you're using pip I would just uninstall selenium with

pip uninstall selenium

Docs for uninstall

Once that's done, install the specific version of selenium you want with

pip install selenium==2.53.1

Docs for installing

Hope this helps,

Doug,
thanks. I missed that section in PIP DOCs. That worked (pip install selenium==2.53.1). Rollback completed successfully.

I'm almost back to where I started. Now when Firefox opens (still using v 49.0.1, not 47.0.1), this error appears...
selenium.common.exceptions.WebDriverException:
Message: Can't load the profile. Profile Dir: C:\DOCUME~1\me\LOCALS~1\Temp\tmp8y2zc13m
If you specified a log_file in the FirefoxBinary constructor, check it for details.

Just rolled back FF win32-enUS-49.0.1 to FF win32-enUS-46.0.1.

Just for the record, I tried using win32-enUS-47.0.1, but it didn't work so I went back to v46. I don't know why FFv47 worked yesterday, but I thought I'd post the results for future reference for older WinXP systems.

I now have selenium 2.53.1 working with FF 46.0.1 on a WinXP Pro (32bit).

That was a painful mistake upgrading to selenium 3.0.0 for WinXP(32bit). The good news is that I learned how to rollback or downgrade.
