Microsoft SQL server 2008 R2 error code 2337 during setup.

I could not start the Microsoft SQL server 2008 R2 setup after this error code. The solution was:

(Step 1 was not required for me!)
1. Save the following in a .reg file and merge to populate the registry:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\100\Bootstrap]
"BootstrapDir"="C:\\Program Files\\Microsoft SQL Server\\100\\Setup Bootstrap\\"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\100\Bootstrap\Setup]
"PatchLevel"="10.50.1600.00"

2. Next, copy the following files and folders from the media to the specified destinations:


File/Folder in media:   
X64/X86 folder (depending on what architecture you want to install)
Destination:
C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\SQLServer2008R2

File/Folder in media:
Setup.exe
Destination:   
C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\SQLServer2008R2

File/Folder in media:
Resources folder
Destination:
C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\SQLServer2008R2

Next, re-run the setup, and it should proceed beyond the point of error this time.
