>My VFP 6 application (.exe) file funs fine on most systems. On some, however, I get an OLE error stating that the class (which class I wonder?) is not registered. The problem seems to appear most often on Win98 machines, but has popped up on a Win2K machine. I do have a class that comes from an OCX. Any help or guidance greatly appreciated.

Is your OCX included into the application setup files? Will it work if you try to manually register OCX with REGSVR32.EXE ?
