Error installing SQL 2008 R2 anyversion. Error code: 1605

Question

SQL Server Setup has encountered the following error:
MsiGetProductInfo failed to retrieve ProductVersion for package with Product Code = '{DF167CE3-60E7-44EA-99EC-2507C51F37AE}'. Error code: 1605..
What I've done so far:
1) Had to re-install Windows 7 because I kept getting a pop up that said my windows was unregistered, which it wasn't (known bug) so I re-installed as per MS recommendation.
2) Un-installed SQL 2008 + ran Microsoft Fix It tool.
3) Tried to re-install but I get this error.
4) After I got the error I deleted all the registry entries per instructions available where other's have posted this same problem. Started by reversing key and deleting what I found in the registry. 
5) When I continued to get the error I renamed the registry directory UpgradeCodes to UpgradeCodes.old. Still fails with the same error.
6) I've rebooted after every step and I've repeated this many times...
In all cases when I try to re-install it fails with Error code: 1605. At this point when I search the registry for the reversed key it is not found. It's gone.
Not sure what to do next.
Any suggestions would be appreciated. Thx

Hi gridmaster54,
According to your description, you fail to install SQL Server 2008 R2 with the error code 1605. Please help to post SQL Server setup error log for analysis. By default, SQL Server setup summary and detail logs are located in C:\Program Files\Microsoft SQL
Server\100\Setup Bootstrap\Log.
Based on my research, this issue could be due to the remains of a previous unfinished installation. To troubleshoot the issue, please pay attention to the points below.
1.Make sure that your account has admin rights and you right-click the setup.exe and choose “Run as administrator” to install SQL Server.
2.Make sure that your account has full control over the following key: HKLM\Software\Microsoft\Windows\CurrentVersion\Installer\UserData\
