Yes. When I was thinking at "closing the file before running the
program" I was actually hinting at the bootloader.
Now, now.
PyInstaller does support a mode in which the .pkg file is not attached
to the bootloader. It is called "non-ELF exe"; as the name hints, it's
currently used only under Linux (see also the Manual, in the EXE section).
The main.c for the bootloader under Linux does pratically this:
if (init(homepath, &thisfile[strlen(homepath)], workpath)) {
/* no pkg there, so try the nonelf configuration */
strcpy(archivefile, thisfile);
strcat(archivefile, ".pkg");
if (init(homepath, &archivefile[strlen(homepath)], workpath)) {
where &thisfile[] is pratically the name of the executable. So Linux'
bootloader is ready for having an external .pkg: it silently fallbacks
to it if it can't find the .pkg attached to the executable.
The Windows bootloader's winmain.c does not support it though:
workpath = getenv( "_MEIPASS2" );
rc = init(here, &thisfile[len], workpath);
if (rc)
return rc;
There are also some other problems here and there to fix to do a clean
patch. I see that class NonELFEXE in Build.py is probably a little
bitrot. From a quick glance, it has duplicated code to compose the
bootloader file name, but should instead share that code with ELFEXE.
After that, one could also add an option to Makespec.py to use
NonELFEXE, so that NonELFEXE basically becomes an user-level feature,
instead of only a configuration option. And maybe rename NonELFEXE to
soemthing more clear ;)
Of course, for your own application, it will be enough to modify
winmain.c so to hardcode "program.pkg" into the init() call. This should
remove the executable lock problem and let MSI do its job.
