Windows: update custom software installed on Program Files
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
Im the developer of a Windows software application which I currently release as "portable", meaning the user needs to extract it somewhere into his disk. Along with it I ship a small update tool (external app / python script converted into an .exe through pyinstaller) that handles updates as follows:
- Main app calls the update tool in the background and quits
- Update tool runs: fetches new files, removes files in the main app directory and extract new ones (the new main app .exe, dlls, and
other files that might be required) - Update tool call main app again
Questions: by creating an installer (NSIS / InnoSetup) and letting the user to install the app in Program Files, will I be able to keep this update tool? I mean, can it have enought permissions to do the update like that? If not, how can/should the updates be done?

It sounds like you just need to have the updater app be able to elevate privileges.
I found the following gist here:
https://gist.github.com/GaryLee/d1cf2089c3a515691919
import sys
import ctypes
def run_as_admin(argv=None, debug=False):
shell32 = ctypes.windll.shell32
if argv is None and shell32.IsUserAnAdmin():
return True
if argv is None:
argv = sys.argv
if hasattr(sys, '_MEIPASS'):
# Support pyinstaller wrapped program.
arguments = map(unicode, argv[1:])
else:
arguments = map(unicode, argv)
argument_line = u' '.join(arguments)
executable = unicode(sys.executable)
if debug:
print 'Command line: ', executable, argument_line
ret = shell32.ShellExecuteW(None, u"runas", executable, argument_line, None, 1)
if int(ret) <= 32:
return False
return None
if __name__ == '__main__':
ret = run_as_admin()
if ret is True:
print 'I have admin privilege.'
raw_input('Press ENTER to exit.')
elif ret is None:
print 'I am elevating to admin privilege.'
raw_input('Press ENTER to exit.')
else:
print 'Error(ret=%d): cannot elevate privilege.' % (ret, )
