Hi Gene,
normally your Starter programm just runs the main program, after checking
for updates, and then quits itself. The starter cannot update himself, thus
another program / task has to do this. The easiest way would be to first
install a new main program, which checks the starter for version, and
optionally does the update for the starter program. Thus the two can update
each other :)

Betreff: VFP App Startup Program
Hello:
I have seen discussions about this at various times, but I have not
ever seen details.
You have an app which might be updated and want to have that happen
automatically.
In my case, it is a VFP .exe, and I wrote a program to handle that
years ago.
What about if the startup program needs to be updated? Since there is
a change (the first since) in that, I wanted to write a version that would
update the update program, too. Somehow, it did not work. And since there
is less debugging information available when debugging a .exe, I ended up
giving up on it after some trouble.
My thought was to have two programs:
cbs2run.exe would check cbs2run2.exe if it needed updating (and maybe
update), check cbs2.exe (the app) if it needed updating (and maybe update),
then run cbs2run2.exe.
cbs2run2.exe would check cbs2run.exe if it needed updating (and maybe
update), then run cbs2.exe.
The reason that I had two programs is so that cbs2run.exe would quit
running and be overwritable. Even inserting a 5-second pause before trying
to overwrite cbs2run.exe in cbs2run2.exe did not work. I got some very
inconsistent and confusing results.
Was I overlooking something? If so, what?
Sincerely,
Gene Wirchenko

Look at my original post. That is exactly what I was trying to
do with cbs2run.exe and cbs2run2.exe. But there was trouble. I do
not know if I simply missed something or it is not possible in one
execution chain.
Sincerely,
Gene Wirchenko
