Are you still having trouble with Windows Live Messenger sign in, even though your WLM version is already the latest version? Whenever you login, you always get a very annoying error pop-up shows saying "Windows Live Communications Platform has encountered a problem and needs to close. We are sorry for the inconvenience"...

??? Windows Live Messenger Sign in Problems: THE TRIGGERS?

According to The official Messenger Support blog;
Sign-in issues with Windows Live Messenger can be triggered by a wide array of probable causes. It might be due to as simple as an incorrect date and time settings on your computer, or as complicated as problems with your Internet connection.

Below, there are some Troubleshooting Steps that may help resolve it.

A. WINDOWS XP users
0. Upgrade your Windows Live Messenger to the latest version. Get it from http://download.live.com

1. Check Date and Time Settings
Just double click your clock on Windows desktop (if you set to display it on taskbar),
-OR-
you can go to Start, click Run, type control timedate.cpl , and then click OK.
In the Date and Time Properties dialog box, confirm that the date and time settings on the computer are correct, and then click OK.

- Check whether the msnmsgr.exe is running on Processes. If it is, select the application and click End Process. If you are prompted, click Yes.
a. Open Windows Explorer. (Right-click Start, and then click Explore to open the Windows Explorer window)
b. Go to C:\Documents and Settings\ Your Windows logon name \Local Settings\Application Data\Microsoft
(If you can't see/navigate it in the folder tree, just type it in the address bar!)
(Note: In these examples, Windows Logon name is the logon name that you use to sign in to Windows.)
c. Delete the Windows Live Contacts folder.

6. Administrator Mode

Clicking on the messenger shortcut, selecting properties and checking the "Run as administrator" box.
-OR-

Re-open Windows Live Messenger and try to sign in again, and verify if the issue remains.

(Note: In these examples, Windows Logon name is the logon name that you use to sign in to Windows.)

6. Administrator Mode
Try running the application as an administrator.

Clicking on the messenger shortcut, selecting properties and checking the "Run as administrator" box.
-OR-
Go to c:\program files\windows live\msnmsgr
Right click msnmsgr.exe and Run as.. administator

7. Data Execution Prevention crashing Messenger in Vista
Vista's DEP Protection may affect your web-based applications. You might need to disable DEP in Vista:

Launch cmd command with administrator rights
a. Go to Start > All Programs > Accessories
b. Right Click on Command Prompt > Run as.. Administrator
(Click the Allow button if it asks you for permission)
c. on the command prompt window, type this:

bcdedit.exe /set {current} nx AlwaysOff

d. press ENTER, a message will appear: "Operation Completed Successfully"
e. Restart your computer and DEP should be disabled.

Re-open Windows Live Messenger and try to sign in again, and verify if the issue remains.

C. WindowBlinds users
If you're using WindowBlinds (read my previous post: How to Transform Windows XP Skins-Visual-Styles-Themes to Vista with WindowBlinds), you'll need to exclude the WLCOMM.EXE application from WindowBlinds, because Windows Live Communication Platform (WLCOMM.EXE) works only with the standard Windows screen.

Here is step by step you have to do:
1. Open your Window Blinds
2. Under "Change the look of a particular application", click "add per application setting"
3. Locate: c:\program files\windows live\contacts and Choose wlcomm.exe
4. check mark: "Ignore this application and do not skin it", click OK.
5. Under WindowBlinds Configuration > "Apply my changes"
6. ..and DONE! just restart your Windows Live Messenger 2009 and sign in.

That works for me, If it doesn't work for you, you can follow the steps appropriate for your computer's Windows Operating System above/below (Option A., B., and E.) that may help resolve the problem.

D. nVidia users
a.Most users with some Asus board with an NVIDIA chipset are going to have the option to install the NFWNAM (NVidia ForceWare Network Access Manager). Unfortunately, it has some sort of firewall built into it that could stop you from connection correctly to MSN.

Try to Uninstall NVidia ForceWare Network Access Manager from control panel Add / Remove Programs, then Restart your computer.
-OR-
Apply Option E.2. below (Move/rename wldlog.dll)

b. nVidia MediaShield might also cause this problem in Vista. You can try to uninstall it.

>>>IF ALL THE STEPS above (A.B.C.and D.) STILL DO NOT SOLVE your problem, not being able to log in, DON'T DESPAIR, you may try these:

E. PLUS OTHER SOLUTIONS ++++
1. Select Compatibility Mode + Disable visual themes on wlcomm.exe
a. Find file wlcomm.exe in the directory: c:\program files\windows live\contacts
b. Right click the file and go to Properties
c. Select compatibility
d. Try to select it to run in windows 95/98 compatibility mode and "Disable visual themes"
2. Move/rename wldlog.dll
a. Go to c:\program files\windows live\contacts
b. rename wldlog.dll to wldlog.dll_resp
-OR-
Move it somewhere safe like My Documents.
(If you need it later, you can just rename back to original or restore it back.)
3 Upgrade Your Windows OS with the latest updates
a. Upgrade Your Windows XP with Service Pack 3 (SP3)
b. Upgrade Your Windows Vista with Service Pack 2 (SP2)
4. Delete everything that involves Windows Live:
-Windows Live Essentials
-Windows Live Sync
-Windows Live Upload Tool
-Windows Live Sign-in Assistant

and then Reinstall a FRESH version of Windows Live Messenger!

IF ALL of above doesn't work for you, THEN your computer might been infected by virus/spyware/malware..

I hope the solutions above fixed your problem with Windows Live Messenger sign in. Good Luck!

:) thanks again

Mike said...

Diane said...

Colin said...

Marco said...

Didnt work :(

Windows Live Communications Platform has stopped working :( =[

Tiffy said...

yea i tried every thing its not working..

lau said...

ive also tried everything and nothing workerd, is there anything else i can try?

Robert Evans said...

Well not sure what I did but I changed the security permissions of the main exe file so that users had the same access as Administrators changed the Owner to myself (log in name) and Enabled the Administrator accunt and logged in as Administrator opened WLM and logged in. Logged off then back in as myself. Also updated to Flash Player 10 which has been suggested but not sure if that is the main fix. Whats very odd WLM worked fine until I allowed it to update to a slightly newer version so maybe the earliest WLM 14.xxxxx is the non plagued one. To be completely honest I think they need to re-think the production team for WLM as clearly somone there is not puling their weight not a good thing when lots of people need a job

Nicole said...

thank you so much!!!!! I did steps 3,4,5 and 6 and my msn is now working :)

play said...

Hi, I have tried to reinstall it on my Vista
Removed Contacts and the old msnmsgr.exe ..
Did not work

When I tried your bcedit - the command prompt said that this was not an internal commando .. i thought at first that maybe I wrote it the wrong way or put a space somewhere .. but nope.. still the same answer..

would appreciate if you knew any other solution to this..

I have not had any problems for a year - and suddenly they just appear after I chose to uninstall MSN Messengers mail service.
Odd coincidence perhaps, or....???

I have no wldlog.dll on my computer - and YES I already have the settings view hidden system files.. etc..

I will try to uninstall my nvidia driver now and restart .. its the only thing I have not tried.. will return if it didnt work

yael said...

Hi, now I have tried all of your suggestions above, except for those that did not apply to my computer.

I have scanned my system for viruses with Avast and it is clean.
Nvidia - uninstalled and restarted.
MSN - installed it again - and it installed everything but messenger and now I can not find the uninstall file so I cant uninstall it or reinstall it.

I went in to the regeditor and took all keys away for messenger, I have done this before for other programs that had no uninstall file and it removed the program completly. That did not work either.

I did not have system restor active, since some viruses takes advantage of that - i do lot of backups instead.

I do not think you can help me, but if you can find a way around this, that would be helpful. Thank you for all your input on this page, although it didnt help me, i am happy it helped a lot of others.

All the best

Yael

dheean said...

Mine doesnt work either.... :( whoaaaa

Raven said...

Just to let everyone know that the problem is not with Nvidia, or any other program. It is the result of a WLM file setting. To resolve this issue got to: (Windows XP users ONLY)

1. C:\Program Files\Windows Live\Contacts
2. Locate the wlcomm file, and right click on it.
3. Go to Properties.
4. Select the Compatibility tab.
5. Under the Display settings make sure the box is checked for disabling visual themes.

People should not be going in a deleting dll's for any reason. You can really mess up other programs, and how they operate. I can't believe it was even a suggestion. Remember, some people are not as pc savvy as others. Hope this was a help in resolving your issue. It worked for me.

jenneth said...

all the steps didnt work for me but tried the last part reinstalled a fresh copy and it worked. thanks

LuisP said...

thanks its working now I rename the wldlog.dll file thnk U very much

wanderSick said...

One simple way that works for any software problem is restore to an earlier restore point before the incident using the built-in System Restore.

Malik Kashif Habib said...

The easiest way to solve this problem is this one:

Go to:
c: program files\windows live\contacts

Right click and go to properties

select compatibility

select disable visual themes

Then you are able to log into MSN messenger 2009.

Evelyn said...

It did not work for me, all that remains is: Windows Live Communications Platform has encountered a problem and needs to close.
