i HAVE FOUND THIS PROBLEM BEFORE.
1ST THE ORIGINAL DOWNLOAD FROM MICROSOFT MSAGENT.EXE < this does work! But there is transparency issues with some characters. I have found to Correct this problem.
SAVE YOUR ORIGINAL (VISTA VERSIONS) or (XP VERSIONS) of,
AgentAnm.dll, AgentCtl.dll, AgentDp2.dll, AgentDPv.dll, AgentMPx.dll, AgentPsh.dll, AGTUI.DLL .
These are to be copied over the ones provided by the original msagent.exe installer. (works fine on lesser versions of windows).
the ones provided in Vista and XP are Updated versions of the one provided in the msagent.exe as it was originally intended for BACKEND users of win95 / winnt as windows 98 comes with the same versions as supplied in the msagent.exe. <PREFERABLY THE VISTA VERSIONS> as these will be the FINAL VERSIONS of the MSAGENT CONTROL.
Hopefully this should clear things up.
PS: the Microsoft link only provides a hot-fix for windows 7 x86 version and will not install on the 64bit... silly Microsoft!
