Thanks for the help everyone. I suppose for now the pc is ok. Seems to be clean. But now his Windows mail won't open. Can't initialize the MSOE.dll. Looks like I've got some more work to do. But thanks again! I'll mark as solved I guess.

Following ’s report that Windows Mail fails with an MSOE.DLL initialization error and ’s earlier suggestions, here are focused diagnostics and safer recovery options that haven’t been covered yet. These aim to identify whether the problem is a per-user store/registry issue, a system-file corruption, a permissions/blocking problem, or a dependency/version mismatch — without blindly swapping DLLs between machines.

A practical first step is to capture the exact fault details from the Application log in Event Viewer (run eventvwr.msc). Note the “Faulting module” name, full path, exception code and offset. Those four values narrow the cause (access denied, corrupted binary, incompatible version, or a dependent DLL missing). If the log shows an access error, check NTFS permissions/ownership on the MSOE.DLL file (System and Administrators need Read & Execute).

Repairing system components often fixes broken system DLLs. On modern Windows versions, run these from an elevated command prompt:

DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow

On older Windows 7 installs, sfc /scannow is the primary tool. These restore correct system copies without risking cross-machine mismatches.

If the problem appears user-specific, testing under a fresh local Windows user account separates per-user mail-store/registry corruption from global system faults. Windows Mail/Live Mail stores are commonly under:
%appdata%\Microsoft\Windows Mail (Windows Mail)
%userprofile%\AppData\Local\Microsoft\Windows Live Mail (Live Mail)
Back up those folders before any changes.

Additional notes: antivirus quarantine can remove or block MSOE.DLL during a cleanup—check AV logs. Using the Windows Essentials installer’s Repair option is safer than copying DLLs from another PC. As a last resort, a System Restore or in-place Windows repair will replace damaged system files. Create a system restore point and back up mail data before making deeper changes.

That is a recurring Outlook error. I'd bet you probably have solved it by now.

If not, let me know and we can take a whack at it.

Actually, I've not fixed the Windows mail issue. Tried a few things. Backed up the folder deleted the contents. Backed up the registry key. Deleted it. He was getting pretty unhappy about losing all his saved mail. So I just hooked him up with Thunderbird, got all his old mail imported and left it at that for now. I would like to solve the Windows mail issue though. I even reinstalled Windows Live Mail and it's still doing the same. Windows live mail keeps saying it encountered an error and needs to close. So I'm wondering if I just take a copy of my MSOE.dll and put it in his windows folder if that would work?

Should I start a new thread or keep this one going? Thanks...

I split this off into a new topic for you.

Go ahead and copy the .dll and see if that helps. Also, re-register it, while you are at it.

Let us know how that shakes out.
