[jamestee81]

Hi I recently purchased two apps for my my phone EasyHelper Information Hide and EasyHelper SMS Security

I am not able able to register the products with the keycodes i was given upon the purchase called tech support and they said make sure my device is correct called htc and they told me how to do so so all that is correct however the apps did not register emailed mobihand and they and they emailed thesse instructins

What should I do if the software doesn't work on Smartphone devices?
A: Most Smartphone devices are in "Security Locked Mode" and you need to unlock your device before installing the software.
Please follow the following 3 steps to unlock your device:
1. Download and install this CAB file on your device.
2. Download and install RegEdit (it is free) if it is not installed.
Then look here:
[HKEY_LOCAL_MACHINE\Security\Policies\Policies]
You have to change these keys (they may look so):
Key "00001001" value must be "1"
Key "00001005" value must be "40"
Key "00001017" value must be "144"
Key "0000101b" value must be "1"

i was able to download the cab file
but not able to download regedit

I am seeking help on doing the registry edit i think this will allow me to register my apps anyone who can please help me i would really appricate it I have a htc touch pro 2 runing wm 6.5
