Why cannot I install Yahoo messenger on company laptop and get error message could not load the dll library?

I extensively use yahoo IM and at this time on an assigment out of home using a company laptop. Tried installaing yahoo IM and get the error message could not load dll library. C:\WINNT\kernel32.dll. The specified module could not be found. However Im able to install other IM softwares like Gtalk, Rediffbol and Skype. What is the problem and why Im not able to install yahoo messenger where as able to install others. Is there any solution or work around to get yahoo installed. Let me know if any one has an answer. Thanks

im wondering if its a company computer if they have settings which stop you downloading messenger. i know some work pcs have that option. you should check with your company if this has happened.
