You didn't offer any situational information around this error. Did you try the steps in the post you responded to? It sounds like the install log doesn't exist there (maybe it was manually deleted, or some files were copied and/or moved).

Try reinstalling (to the same directory you originally installed), then uninstall. That should solve the problem. If not, please let us know more about the situation (ie: install directory, what steps you've tried, etc.).
