Hi,
you are trying to install SAS 9,4 M3 on Program FIles\SASHome.
Is it possible that you had a previous SAS installation on that folder? Was it SAS 9.4? SAS 9.3?
If it is SAS 9,4, then you dont need to install, but to upgrade then install the remaining components you need.
If it is a previous version of SAS, I would recommend you to install on a different folder (as Program Files\SAS94 as an example).
And now, you installed previous components. But it needs to overwrite some files of your current installation:
Check that you are installing enterprise guide only. And if you can verify that, then the last thing is to do what @jklaverstijn corretly suggested.
