This doesn't work on OSX 10.7 10.8 and 10.9 for Adobe Drive 5 using aamee 3.1. I also get the message a valid installer could not be found. It worked fine on my Windows 7x64 machine.
Was your issue resolved markc0?
I just noticed that when i run the Adobe Drive 5 installer it wants to install adobe drive at the following location
/Library/Application Support/Adobe/Adobe Drive 4 
So i looked at the AdobeDrive5-mul.install.xml contents
<Deployment>
<Properties>
<!--Note that the INSTALLDIR value is machine specific. The value below is a suggested default value but may need to be overriden.-->
<Property name="INSTALLDIR">/Library/Application Support/Adobe/Adobe Drive 4</Property>
<Property name="installLanguage">cs_CZ</Property>
<!--The set of valid languages includes:
cs_CZ
da_DK
It installs just fine when running outside AAMEE and i don't think the install location matters but just wanted to point it out as this is the only discrepancy i could find.
