I have installed codemanager on localhost he finalize button wasn't working because it was sending wrong path ( slashes missing backslash / forward slash ) I hardcoded path in process.php , however now the error is with projects path , its not picking up local path like C:\wamp\www\oc56 I tried to edit projects.php 

I'm running into the same issue installing on localhost with opencart 1.5.6.4

On windows I was able to fix the issue by changing the backslashes in my both admin and frontend config.php files  to forward slashes. and remove "c:" from the beginning of the paths so it begins as /wamp instead of c:/wamp ..Ajax doesnt seem to like the backslashes in the the paths and is removing them and causing the finish button to throw a bunch of errors. 

Hello guys,

CodeManager will most probably not work on a localhost since it is not designed for it. However, I see that @Raul Rodrigues is offering a solution that might work so you can try and see the outcome.

Hope this helps!
