--- Comment #22 from Chris Caudle winehq@chriscaudle.org --- (In reply to Zebediah Figura from comment #21)
We don't actually prevent access to system files. In fact, we don't actually restrict access to anything at all just based on whether the user is reported as an administrator. However, some applications demand to be treated as one or the other, and call dedicated APIs to check the elevation of the current process.
I have run this application on Windows before, both from an administrator account, and a restricted user account. From the restricted user account when the application needed to update the directories in Program Files there was a system dialog which popped up to request a login from an administrator enabled account. So maybe this problem is not related to 39262 after all.
