Hiya,

Recently I have not been able to work Msn Messenger 7.5. I've tried a myriad of things to fix it (I'm not that good with computers)! I've tried uninstalling it, re-installing it, installing different versions etc. The errors I am getting are:

Can anyone help?!?
Thanks heaps,
Mary

Try registering the necessary .dll files:

Click Start / Run / type in (or Copy/Paste); regsvr32 Dssenh.dll /s

Do the same, for each of the following:

regsvr32 Gpkcsp.dll /s
regsvr32 Slbcsp.dll /s
regsvr32 Sccbase.dll /s
regsvr32 Softpub.dll /s
regsvr32 Wintrust.dll /s
regsvr32 Initpki.dll /s
regsvr32 Rsaenh.dll /s
regsvr32 Mssip32.dll /s
regsvr32 Cryptdlg.dll /s
regsvr32 Msxml3.dll /s

Some times, when trying to register Msxml3.dll, you will receive a message that it has failed.
If you receive this message, go to Microsoft XML Parser (MSXML) 3.0 Service Pack 7 (SP7), scroll to the bottom, download, and install msxml3.msi.

Reboot, and try Messenger again.
