I have the same error coming up, but my situation is a “little” different. I have sysprep set up, so that once my server is powered on for the first time, it does the SQL Server 2008 R2 install from command line. Works like a charm! I then have it install SP1 from command line with the following command:
“C:ServerBuildSQLInstallationSQLSPsetup.exe” /QUIETSIMPLE /ALLINSTANCES /INDICATEPROGRESS /IACCEPTSQLSERVERLICENSETERMS
…which halts at the above error. Keep in mind, I am intending all of this to be “silent”, from the unattend file. I can’t really “remove” .net4 and then “readd”. The files are already completely local (I downloaded the .exe, and extracted all into the C:…SQLSP directory. All files all there, so this should not be an issue?
Anyone have direction further on this as to how I can do this from a fully automated perspective?
