Hello,
SEP_Inst.docx shows the following errors:
ScriptGen: ShowServiceProgress() script execution failed.
ScriptGen: ShowServiceProgress() reset script failure event.
ScriptGen: ShowServiceProgress() is returning an error (so close to the end!)
CustomAction ShowServiceProgress returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)

and SIS_Inst.docx shows

In your case here are the suggestions -
Please ensure that the UAC is disabled on the Windows 7 machine and Disable Windows Defender before installing the SEP client
Could you try installing the SEP 12.1 RU4 on the Windows 7 machine.
