I've had many problems with MSHFlexgrid because of the updates, I already tryed many things, for example I registered it, put the DWord value as 0 in regedit, changed UAC values, etc, and nothing works. I still get the "The subject is not trusted for the specified action" message.

So I decided to replace MSHFlexgrid control for Spreadsheet control.
I use the control in a userform in a Excel file, and the control is only going to display data.

Any comments or suggestions?
