returned false Error: Action "ParseBootstrapOptionsAction" failed during execution

I had a failed SQL Server 2005 installation with the following error (not the complete error messages):

......

Error: Action "ParseBootstrapOptionsAction" failed during execution. Error information reported during run:

Called MS Support and she asked me to check and compare the following registry keys:
1) HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
2) HKEY_USERS\S-1-5-18\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders

I found that only Local AppData entry was there, others were missing. Then I added each value to the first key by referring to the values in the second key.

Then I restarted installation again, successful!!
