>After reading the faq entry "What Run-Time files do I ship with my App?", I'm wondering about the statement "And you must also run DCom98.exe (95/98) on the users system."

If DCOM support is not present (generally, this applies to Win95 boxes that have never had IE 4 or later installed) you need to install the DCOM support files on the workstation. DCOM98 only applies to Win95/Win98.

There's a registry key you can check to see if DCOM is present; the VSI is capable of checking for this.

>Does this mean that I always have to do this prior to installing my app on a users machine? How do you do this?

Using Installshield, I check the registry, check the OS type, and display a dialog that tells them what to install if DCOM is not present. Now that Symantec and NAI are starting to set minimum supportable software environments for some of their products, I'm moving in that direction, too - I don't need customers who want to run a large VFP app on an 8MB Pentium 100 with original Win95; the headaches aren't worth it.
