is it possible to create SIS_Inst.log manually?

hi all,

there's equivelent command that use "msiexec /i "SEP.msi" /L*V SEP_Inst.log to create SEP_Inst.log while the installation failed at initial period.

is there any equivelent command to create SIS_Inst.log?

I met a SEP install failed case, SEP_Inst.log was  generated successfully but SIS_Inst.log is missing, I've searched whole disk still can't find it.

thanks!

Regards,
