Method of searching any application installed or any file related to that on Macbook? Recently I installed LogMeIn app, and installation was done properly. There was no icon of app was made. I am searching but I am not getting the file or app related information in the system file. I am not sure whether it is Hidden or not. Or it got uninstalled automatically. Now, What I want is, how can I search my entire Macbook which looks into all files either hidden or not hidden, and tells me whether there is any file related to that app or not with complete surety.

Note: I did search about this app on internet and people are saying that it is hard to locate the files of this app and it is hard to delete and does not show up in normal search, even I tried their methods but it is not helping. So first I want to make sure that whether that app is there or not.
First off, if you just google the words uninstall logmein mac, you will find the vendor's Help entry on where to find and delete the relevant files... 

In general, it's rather difficult to track every file installed by one application installer (that is if the application files are not consequently self-contained within the .app file).

A) The Finder's Spotlight search has an option to search files by their date of addition, but the Spotlight search doesn't include Library and System folders. A better search application I would recommend instead would be Easy Find (freeware by Devon Technologies). It has extensive search options and will walk through the whole system, and includes hidden files/folders. 

B) If the application installer came as a standard installer package, a '.pkg file', you can often use the package tool Pacifist (shareware by CharlesSoft) to open it and list the contained files with their target folder locations (in Unix: directories) on the machine. Then you go to these folders in Finder (or the Terminal) and delete files/folders 'manually'.
