em Client - how to remove it completely from my pc

My OS is win 7 prof 64 bit and i had installed eM Client ver 5. ... (sorry I cannot remember) and then did a Revo uninstaller to uninstall everything (the Advanced feature), and then I downloaded eM Client ver 6.0 which is the latest version and tried to do a fresh install.  But the error says that i have still another version of em Client in my Pc, and the install was aborted.  
The Q is how do I remove all traces of em Client from my PC.  Thank u.

This reference offers a detailed procedure to remove eMClient 5...  It involves reinstalling eMClient 5...

If that does not help, have you looked in Control Panel|Programs and Features to see if there are any bits of eM Client still installed?  For example, eM Client SecurityCenter.  

Run a Search in Windows  for eM Client.  Delete as you find left over bits.

Enter the Registry and run a Edit|Find for eM Client.  Delete as you find left over values.  Back up your Registry before you do that.
