Windows Live Messenger 80040154 Sign In Error

Heres what I came up with to fix the Windows Live Messenger 80040154 Sign In Error
and it works for me
First of all you can try what microsoft suggests when you google this error,
which is what I tried...nothing work!!! Heres my solution that worked for me.
My operating system is windows xp home edition.
Lets get started with the fix that worked for me...

1. First of all you need to uninstall windows live messenger...just a normal uninstall
will do fine...

2. Now you need to have either two hard drives on your computer or
at least one hard drive which has been partitioned.

3. Providing step two has been fulfilled go to Start - Run - then type in Regedit
& back up your registry... If you are unclear on how to do this just google it.

4. Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

5. Find ProgramFilesDir whose default should be C:\Program Files

6. Change this to whatever directory you wish. I changed it to D:\Program Files for example.

Remember you have to reboot for your changes to show.

7. Once you have rebooted go ahead & download windows live messenger & install it...

8. Once you have started it up and all is working well, turn off windows live messenger.

9. Navigate again to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

10. Find ProgramFilesDir whose default should be now be D:\Program Files
or whatever you changed it to & change it back to what it was before.
You don't have to... its up to you... but if you don't all new programs you install
from now on will go to D:\Program Files instead of C:\Program Files for example.

11. If you didn't change it back then you are done... if you did change it back
go to the next step...

12. If you did change the default program directory back to where it was,
do a right click on your windows live messenger icon then click properties
& change the path from "C:\program files\Windows Live\Messenger\msnmsgr.exe"
to "D:\programme\Windows Live\Messenger\msnmsgr.exe" or where ever you
changed it to in the registry. All you do is replace the C with a D or whatever
drive letter you changed it to in the registry...
All done I hope this helps everyone who has been troubled with this problem.
