I know this installation issue has been brought up before, but it never seems to get clearly answered, so I thought I'd post it again since I'm experiencing some problems with a fresh installation of DNN4.5.1. I get the following error:

Configuration Error

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

It seems to be referencing my "dnn437" folder, which contains an older DNN installation. Why it's looking in this folder for ANYTHING is beyond me. Anyone know what's causing this, or how to address it?

Thanks!

I used the web.config file from the new 4.5.1 install, didn't make any changes to it at all.

I double-checked it, and is pointed to the correct folder. Is it a problem that I'm running multiple versions of DNN on one machine? (I've got 4.3.7 and 4.4.1 already installed)
