You will want to kill the PowerChute.exe, apcsystray.exe, mainserve.exe, and dataserv.exe processes if running before you do the following steps
 

1. From the installation directory in Explorer

(e.g. 32 Bit - C:\Program Files\APC\APC PowerChute Personal Edition

64 Bit - C:\Program Files (x86)\APC\APC PowerChute Personal Edition) remove the entire contents from the first 'APC' down, that is assuming you used the default path and you do not have any other APC products installed.

 

2.a In the Registry (open by going to Start->Run->type 'regedit') a. go to the

32 bit - 'My Computer\HKEY_LOCAL_MACHINE\Software\APC' key.

64 bit - 'My Computer\HKEY_LOCAL_MACHINE|\Wow6432Node\APC.

If you do not have any other APC products installed delete the entire APC key, otherwise just delete the APC PowerChute Personal Edition key.
 

2.b Go to the registry

32 Bit - 'My Computer\HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall'

64 Bit - 'My Computer\HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall and then search for PowerChute Personal Edition.

This should return a key with the following contents:
DisplayName
UninstallString.
Remove the entire key where the match occurs.

*Note: Keep a track on the 'name of the string', it should be something like {F1486DE6-CC2E-48C0-AD20-C2C142FA1636}, but this will be depend on what Windows installer assign to it.
 

2.c Go to registry on both 32 bit and 64 bit machines - 'My Computer\HKEY_LOCAL_MACHINE\Software\Classes\Installer\Products\'

search for 'PowerChute Personal edition'.

This should return a key with the following content:

ProductName

Remove the entire key where the match occurs
