Try the instructions here: http://sites.google.com/site/oblivionpoinfo/prep/wrye-bash. The important files for Bash are all installed in your Oblivion folder.
Edit: wording, The requirements have "regular" installations, and are not specific to Oblivion.
here are the instructions.
# If you do not have it already, download and install 7-zip.
>> notes: You may have to restart your computer. If so, go ahead and do that now.
# Download the Bash dependencies: Python 2.6.4, wxpython 2.8.10.1 ansi , ComTypes, psyco 1.6 for Python 2.6, and PyWin32 for Python 2.6.
>> notes: 1) Make sure the version of ComTypes you download supports Python 2.6. 2) Some users have reported that using Python 2.6.5 works as well.
# Download the latest (archive) version of Wrye Bash and the Wrye Python 02 package.
# Install the Wrye Python 02 package: Extract and run the executables for the dependencies. "WHAT DOES THIS MEAN??
# Extract Wrye Bash to your Oblivion folder. (It should add the folder "Mopy" there.)
>> notes: Bash also adds a few folders to the Data folder as well.
# Create a Wrye Bash shortcut.
1. Right-click on Oblivion\Mopy\Wyre Bash Launcher.pyw
2. Choose "copy"
3. Right-click on the desktop or quick launch bar
4. Choose "paste shortcut."
"Extract and run the executables for the dependencies."WHAT DOES THIS MEAN??
Also, I was able to install Wrye without 7zip...is there something wrong with that??
If I need to start the WRYE installation over again, is there anything I should be on the lookout for??
