Difference between Microsoft Access Runtime and Retail

Hi,

One of my clients asked me to give him a list of all the machines that runs MS Access Retail and list of MS Access Run-time.

I looked and looked and couldn't find any differences between the versions. The files are the same, the DLL's are the same. I was frustrated.

I used procmon.exe from sysinternal and found that there is no difference in the actual files but only registry settings !!!

Here there are:

[HKEY_CLASSES_ROOT\Licenses\73A4C9C1-D68D-11d0-98BF-00A0C90DC8D9\11.0\Runtime]
@="rldvasjwmvjfrcatkskctmtjahdnkccdgjds"


[HKEY_CLASSES_ROOT\Licenses\73A4C9C1-D68D-11d0-98BF-00A0C90DC8D9\11.0\Retail]
@="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
