BE installation issue

good morning

Due to an HD issue, I have to reinstall BE 12.5

the installation runs properly until the SQL installation

the autorun.inf could not be extract, we can not add .this file anymore to our servers

I have tried to install first the SQLServer2005_BC (install without any issue) and than re-run the installation of BE

still the same issue

I have downloaded the trial version 2014, same issue

I have run with a local admin

I have run with a domain admin

without success

any idea how I can managed this ?

thanks a lot
