I am trying to install SEP 12 on Windows XP, but during installing the setup.exe give rollback, and do not finish the install.
Please navigate to Start > Run and type %temp%
Look for SEP_INST log and post it here for review.
There can be various reasons for Roll Back. As adviced by Brian please upload the SEP_INST Log file to get the accurate reasona and solution
Could you please provide SEP_INST.LOG ?
Os version ?
