Q: 

Getting "Invalid Floating Point" error with ActiveX Control in Delphi

A vendor has developed an ActiveX control in Microsoft C++. The ActiveX worked fine when they were using the 16bit version of the compiler. The control does not work when compiled using the 32bit version within the Delphi2007/D7 environments. If you drop a control on a form and run it throws an "Floating Point Error".

It is a Delphi issue. We are able to use the ActiveX in other applications.

Anyone ever have a similar problem or have a solution for this?

+4  A: 

Sounds like an FPU problem - check out Set8087CW in Delphi's help file.

Absolutely agree. Same thing happens with Quicktime ActiveX control.

Thank you both for your answers. Turns this was the solution. For what it is worth, the ActiveX was by a company called Pictometry. This is a highly graphical software product.
