Hamachi -Failed to connect to the engine

The LogMeIn Hamachi Tunneling Engine service failed to start due to the following error:
The service did not respond to the start or control request in a timely fashion. 

Why do I receive Failed to Connect to Engine?

The error "Failed to connect to engine" is caused by the LogMeIn Hamachi Tunneling Engine either failing to start, being in an error state, or being blocked by anti-virus software.

Engine not running properly

To find the status of the engine:
  1. Press the Windows key and the [R] key on the keyboard.
  2. In the run box type services.msc, and press [Enter].
  3. Look for the LogMeIn Hamachi Tunneling Engine.
If the engine is in any of the following states:
  • Started
  • Starting
  • Stopping
Then try restarting either the service, or the entire computer.
On all OS other than Windows 64 bit, if the service is not running or you receive an error upon start-up, check the following registry location: HKEY_LOCAL_MACHINE\SOFTWARE\LogMeIn Hamachi
On Windows 64 bit, check here: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\LogMeIn Hamachi
There should be a String Value (REG_SZ) labeled EngineConfigDir.  If this is not present, create it by right clicking in the blank space and choosing New > String Value.
C:\Documents and Settings\Default User\Local Settings\Application Data\LogMeIn Hamachi
 You may enter any folder location you desire, and it will create the necessary files there for the engine to run.
Please use care when accessing the Windows Registry.  Consult with your IT support if you are unsure how to proceed.

Blocked by anti-virus

If your anti-virus software is reporting/blocking Hamachi-2-ui.exe, you will need to add an exclusion for the Hamachi-2-ui.exe program.  Please consult your anti-virus software documentation for assistance with adding an exclusion to the allowed list.
the solution is the following for those that cannot find the service or the service seems to be always on starting

open cmd.exe
write cd\
go to  the hamachi program directory
then cd "C:\Program Files (x86)\LogMeIn Hamachi" to go to hamachi installation directory (change to your own path as necessary)
then write hamachi-2 -u
to uninstall the tunneling engine
then write hamachi-2 -i
to install the tunellingengine

if it dosn't start automatically write
hamachi-2 -s
to start the engine
Fixing this issue is very simple. Here was what I've done to start the Print Spooler:
1. Click Start, type “services.msc” and hit Enter.
2. Scroll down to Print spooler.
3. Right-click Print spooler, then select Properties.
4. Select the Log On tab, and uncheck the Allow service to interact with desktop setting.

(Microsoft recommends that you do not change the Allow service to interact with desktop setting. If you allow the service to interact with the desktop, any information that the service displays on the desktop will also be displayed on an interactive user's desktop. A malicious user could then take control of the service or attack it from the interactive desktop).

5. Once you have uncheck this setting, select the General tab and click "Start" (the Print Spooler should be able to start without popping up the Error 1053 again).
Upon installing either Hamachi again, or Kaspersky Anti Virus, various services would yield error 1503 again. Uninstalling one or the other (which ever had caused it at time of install) fixed it. So a format ultimately did nothing.
I had no idea what was causing the issue or even what it really was. I tried everything for the print spooler service, when I instead should have been thinking larger. Whatever was in fact causing it was causing issues with multiple services, notably Print Spooler and Hamchi's Engine Tunneling service. They weren't corrupted, but rather something causing a conflict. Doing the 1 second step I found at MS Answers cured everything having an issue from starting.
