so the software does not employ certificate stores at all but loads the certificate on launch?

in any case, like I said, dir() will be your ticket.

you can search the board for some dir() code and the manual most likely has an example as well. something like:
 Code:
$folder=dir('c:\users')
while $folder<>''
 if '%userprofile%'<>'c:\users\'+folder
  del 'c:\users\'+folder+'\thecertfile.cer'
 endif
$folder=dir()
loop
