Hello...
I know this issue has been on several tickets but I have not been able to find a satisfactory solution. I am receiving error 0x85640001 "...error calculating instanceid" when I attempt to install SQL Server 2012 Developer Edition DVD. I have downloaded the ISO for the enterprise evaluation product and tried burning it to a DVD-RW and decompressing the ISO to my desktop for installation without success.
The log files do state the setup process runs into a badimageformat exception.
I had SQL Server 2008 Developer edition installed on this laptop, but I have completely removed all prior SQL Server instances (using the uninstall wizard in Control Panel).
Please let me know what you suggest to correct this problem.
Thank you for your help!
