>I seemed to have found what was causing the problem, using a very scientific method (metodom nauchnogo tika <g>). If I exclude the Foxpro 9 HTML Help Support msm I don't get the error message. My application comes with a .CHM help, hopefully it will work even without the VFP 9 HTML Help support.

I don't think VFP help will work w/o those files but you can always include them w/o merge module.
