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.

Do you have a suggestion to solve this problem? (Or do you know if there is a third party product to unzip files, it must be zip)

Thanks,
Marco
