You need old version virtualenv version < 1.8
virtualenv version 1.7 can be downloaded from (https://pypi.python.org/pypi/virtualenv/1.7).

However, you don't need to install that version, but just need to use virtualenv.py inside of package. What this means is running virtualenv.py by your default python (python2.7)

on Linux / Mac, command will be like below

python /{download folder path}/virtualenv-1.7/virtualenv.py -p python2.4 {wanted environment name}

For your case, environment is windows and if Python2.7 path is set as environment variable and also assume that you download virtualenv-1.7.tar.gz under c:\temp, then below is the exact command you want to run after unarchiving it.

C:\Users\martin> python C:\temp\virtualenv-1.7\virtualenv.py -p C:\apps\Python24\python.exe env24_v
