Go into "search" and find all the copies of MSVCRT.dll. Some times when a new program is installed, it adds a new version of Windows files. The problem is, that this may not really be the problem! MSVCRT.dll is the "mother" of many "child" dll's. The last time I had a problem with this dll, it took e-mail back and forth with MicroShaft to figure it out. You may have to do a re-install of 98 over itself to solve this (won't hurt anything, but you will have to re-install all your Windows updates).
