Which operative system are you using and which splunk version?
have you an antivirus, because it seems that there's a problem on a single process to start.
Eventually open a Case to Splunk Support.
this means that there isn't any compatibility problem.
Check if there's an antivirus or some other protection system that requiresi a definition of the acceptable processes.
Then which user are you using to run splunk?
Anyway, open a Case to Splunk Support.
