Common error message seen when trying to uninstall or reinstall MSN messenger. Here’s the fix.

When uninstalling MSN messenger or reinstalling it, sometimes people get one of the following errors:

Signing into MSN messenger failed because the service is temporarily unavailable. Please try again later. 800b0001

Signing in to .NET Messenger Service failed because the service is temporarily unavailable. Please try again later.

By re-registering some files, this is pretty easily fixed.

Fix:

1. Click Start
2. Click Run
3. In the textbox type: cmd.exe
4. Click OK
5. The command window will open. Type the following commands in the command window and press ENTER. Some of these commands make take up to 60 seconds to execute. Just wait for each one to complete before entering the next one.

[list] regsvr32 Mssip32.dll
regsvr32 Softpub.dll
regsvr32 Initpki.dll

6. Usually this seems to work. However, if this doesn’t work, you may need to register more files. Here are the common trouble-makers. Continue to enter these into the command window:

regsvr32 Cryptdlg.dll
regsvr32 Rsaenh.dll
regsvr32 Gpkcsp.dll
regsvr32 Dssenh.dll
regsvr32 Slbcsp.dll
regsvr32 Mssip32.dll
regsvr32 Wintrust.dll
regsvr32 Sccbase.dll
