Hi,
Was getting the below error while trying to install
Microsoft Dynamics CRM 2013 Report Authoring Extension (with SQL Server Data Tools support)
https://www.microsoft.com/en-us/download/details.aspx?id=40343g

The solution was to delete the following registry key
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Components\0EF1E6B4EFCDA2649B26A424D56DAACD

After deleting the key the installation was successful.

Hope it helps..
