First, do not be concerned.  These are controls for charting and the application will work even if you see this error.

During installation of BioComp Profit or iImprove, setup reports that the ocx's olch2x7 and olch3x7 do not register properly.  The cause is unknown and does not occur on Windows 2000 Professional, but we have observed that if you reboot your machine and close all memory resident programs, specially virus scan, you won't get the error.  Charting works okay even if you receive this error.
