I messed up when uninstalling solid works and now

Ok so from the begining... I was told to do a fresh instal and remove the solidworks 2011-2012 and install version 2012-2013

So i deleted all of solidworks files that i could find but then relized i was supols to run the solidworks uninstaller. So i ran tht anyways and it said it worked so then i followed what everyone said online about the regedit keys and all the other files i needed to delete. Now i thought i got everything but everytime i click to install it it stop with the error log below. So after so mnny trys i was told to use ccleaner and delete all reg errors and i did this but still nothing. Is there a program i could download and run tha will scan my computer of all the solidworks files and clarify that they are deleated and find the ones that arnt. ----ERROR LOG BELOW---

I will enthisize this part... If you want more of the logs you need to ask me because i didnt know what codes on there are private.
