The uninstall process has failed... you need to ensure the uninstall is clean, before proceeding.

Try to consider a reboot after uninstall.

btw, try to install from a diferent iso... ensure also the OS is compatible with your SQL version

do you mean install different ISO of same version 2008 R2, like install standard instead of Enterprise?


i am using windows 7 x64 ultimate OS

i downloaded en_sql_server_2008_r2_standard_x86_x64_ia64_dvd_521546.iso and started installation, but before install finish i got same error of "Could not find the Database Engine startup handle"
