I'm very new to Inno so I haven't used Scripts yet. I compile this into
my install script and I get Unknown identifier OldExe. Is OldExe a
variable that holds the path to the old executable?
I have another question. My current package uses VFP9, if I apply SP1
and rebuild will the script handle upgrading any installations that have
RTM or are there flags to set to make sure that runtime stuff gets
upgraded too?
Regards
Rodney
