>>>>We like to unzip a file from within our VFP 6.0 program. So we call pkunzip to do the job (!PKUNZIP ...) On most machines this works fine but on one machine we get the message 'Cannot find command.com'. However we can start a dos-prompt and even pkunzip manually. The machine has a correct path and comspec. There is no FoxRun.pif because there is no VFP6.0 installed but if I create one it won't work. Even make copies from the command.com to all common directories won't help.

If this is Win9x, make sure that the \WINDOWS and \WINDOWS\COMMAND directories are in the search path. If this is NT, check the AUTOEXEC.NT for the system, and you might want to associate a custom one with PKUNZIP.

Going back to the original problem, look in your config.sys file and see if there's a SHELL= command. If there is, try REMmin it...
