I had installed SQL 2012 Enterprise on my Windows 8.1 and was running successfully. I faced some SSRS & SSIS Authentication issue. So i decided to uninstall SQL and re-install it. On doing so, i am unable to install it.
Wizard disappears from this screenshot onwards.
Tried installing from Command Prompt.
Setup.exe /q /ACTION=Repair /INSTANCENAME=instancename /IAcceptSqlserverLicenseTerms=true
Still wizard disappears.
