Hello, Alberto!
Thank you for your help.
Of course, I do have local administrative privileges on this computer (and do not have administrative privileges in domain or forest). It seems like setup has failed installation and did not finish all the operations correctly. At least I do not even see system MDBs and the DATA folder. So it seems like setup registered DB service but failed to create complementary files causing service to be unable to start correctly.
How do you recommend to proceed with the uninstallation? I see multiple SQL component records in the Add or Remove applet. Which one should I start with? Microsoft SQL Server 2008 R2 (64-bit) (I have 2 records of these), SNAC, Microsoft SQL Server 2008 R2 Setup (English) or Microsoft SQL Server 2008 R2 Setup Support Files?
Thank you.
Regards,
Stanislav.
P.S.: Thanks to Malcolm for moving this thread to a correct forum. I am sorry to create it in a wrong forum.
