Standalone does not need Python installed .. Thats the only difference oh except you cant run standalone in debug mode I think.
294 Standalone and 294 Python based were both built from the same code so functionally neither is better than the other, they both have all the same capabilities which work the same way.
The Installer version includes both Python based and Standalone versions of Wrye Bash.
The archive version includes Python based but is a manual install, and you need Wrye Python 04a installed too.
The Standalone version is similarly a manual install. But doesnt need Wrye Python 04a.
Notes about the Installer:
Choose Oblivion and Standalone, but no Python options should just install Standalone.
or
Choose Oblivion and Python - Will install the Python version, but on the next screen it will ask if you want to install Python, just click next and dont put a check in the box because this bit is currently bugged and you still need to install Wrye Python 04a.
Notes about Python: Should you decide to go down the python route instead ...
If you have had a previous version of Python installed, fully un-install the previous version first before using Wrye Python 04a - Re-installing python, either over the top of the last one, or by using the python un-installer first .. can cause problems too.
Best procedure is to fully un-install python via the windows Control Panel, Porgrams and Features, Un-install a program
Once the list of installed programs is up, scroll down it and find all Python components (wxPython, Comtypes etc), uninstall each of them BUT leave the main Python installation until last. Then uninstall that. http://www.bild.me/bild.php?file=9634804WBTips-Uninstalling-Python.PNG
Now install WryePython04a (dont un-check anything, just yes, next everything), and let each part finish writing to your HD before going onto the next part (ie dont just quickly next next next)
Then using Wrye Bash 294 beta, check in the box for Oblivion, and Python - Next, on the next screen it may not recognise you have python installed (but you dont need it because you have just installed it) so click next.
When alls done, go to your Oblivion\Mopy\ folder, and find Wrye Bash Launcher, right click it and send to desktop for a convenient icon. Launch it.
