Right - solution!
I've completely changed my angle of attack on this one. I figure that if we aren't able to modify user permissions programatically (for whatever reason), then another way might be to do it at install time.
In InnoSetup, its simply a case of adding the following to the script (I put it below the [Tasks] section, don't think it matters though):
In Vista, this creates a folder at "C:\ProgramData\Your Company Name\Your Game Title\". Permissions are set to 'everyone', and all users can create/read/write/modify anything in that folder, since permissions for all created files are inherited from the parent folder.
[edit] If your users might need to delete files too, then non-owners will need full access instead:
[/edit]
Also tested this under XP and all is well.
From Blitzmax, use the code below to find the common application data path, then tack your company name and game title onto the end, so that you're accessing the same folder which your installer created:
