This post describes how to resolve the error that one might encounter while installing SQL Server 2008 R2 from an ISO.
I had the setup for SQL Server 2008 R2 in an ISO file. I assumed that extracting the ISO using WinZip/Winrar and installing the setup would work and so followed the same procedure. But this was failing everytime. I even tried downloading the same ISO again and installing but got the very same result again.
The ISO needs to be mounted as a separate drive on your PC and only after that, when you run the setup, there won’t be any errors. To mount the ISO, you can use software like VirtualCloneDrive (this was what I used). VirtualCloneDrive basically takes the ISO and mounts it as a separate drive in your “My Computer”; something like this :
1) This is how the ISO file appears when Virtual Clone Drive is installed.
2) After double-clicking the ISO:
3) Open the newly mounted drive to start with the setup
This resolved the problem for me. Extracting an ISO using Winzip and Winrar will not work. An ISO has to be mounted as a separate drive.
And of course, I’m always open for corrections. Please do let me know if I am mistaken anywhere and the post needs changes, I’ll be happy to correct the same.
Hope this helps!
