Thanks for the comments. It's been a useful learning experience anyway - I'm
a good deal wiser and only a little older and that's always a winner:)


Best wishes.

It kinda could have, I suppose, still automatically changing permissions on
folder to facilitate requested write/create/modify would go very much
against my expectations.

As for the original question, creating appropriate folder structure with
installer would imo be a proper way to go.

Subject: [Boost-users] boost::filesystem and writing to Windows programdata




I've an application that has been working fine under Windows 7, but I'm now
fixing up for running on later Windows versions. I've been hitting unhandled
exceptions when writing to c:\programdata\(my company)\(my app name)\ and
understand that this is due to the permissions for such folders being more
restrictive on Windows 8, 8.1 and 10.


My research seems to indicate that I can modify my installer to set up my
folders with appropriate permissions at install-time, but I'd prefer to use
boost::filesystem to check folder/file permissions then change them at
run-time, if necessary using appropriate csidl values.


Can anybody offer any advice, please?


Best wishes.
