solman 7.0 to 7.1 upgrade issue in execution Phase

Hello All,

we are facing an issue (execution phase) while doing solman upgrade from 7.0 to 7.1 SP08

My kernel version 721 300 level

I have tried few methods to overcome this issue

1) we are performing Upgrade on clone machine copy of production system (Clone machine its not in domain)

but production system solman 7.0 has installed in domain

2)Given full authorization for sid<adm>, even its not deleting dll files

3)tried manually deleted dllfiles, if i run next step, asking another dll files to delete

Please help me
