Bottom Line:

I need to set up one game on my little sister's laptop to run without requiring an admin password/account. Its the only game that seems to insist on it... so far.

Detailed Version:

I set up my 14-year-old sister as a regular user on her Windows 7 Home Premium laptop, and almost everything has been fine - until she found a new game (Flyff) that doesn't seem to want to run without an Admin Password (or being logged in as an Admin).

For what should be obvious reasons, I'm not going to make her an Admin. or give her the Admin password (which she swears she'll only use to run this game... anyone else buying that? Bueller?)

Also, the parents aren't admins on her laptop (they are on their own, but that's another discussion for another day) and I'm not going to set them up as one as I know from past experience that the 3rd time my sister asks them to put in their password, they'll just tell her what it is - at which point I might as well as have just set her up as an admin from the outset.

This is a Win7 Home Premium (64-bit, but I doubt that makes a difference) laptop, so using GPEdit is out.

I also tried an answer provided in a related (but less specific) question. The app has read/write permissions for its folder in Program Files (x86), yet that doesn't seem to make a difference.

I have not yet dug through the registry as mentioned in another answer to the aforementioned question.

Just to be thorough, I have checked the "Run as Admin" option on the shortcut's properties to no avail.

Am I missing something?

Addendum 2010-11-11:

Re-Checked permissions as per Joel's answer, and it didn't make a difference.

Followed Jane T's suggestion (and Aeo's second) and created a "Games" folder outside Program Files, installing the game there - and making sure regular users had all the permissions they would need. No joy.

After the latter of the above two changes, it occurred to me that it may be a UAC issue, so for kicks I turned off UAC - still the damn message.

Last item noted: could it be a result of the publisher not being specified/verified? I've been taking a closer look at the error message and it occurred to me that the missing/unverified publisher info could have been the problem all along... Correct me if I'm wrong, but if that's the case, that means there's nothing I can do short of giving her some sort of Admin privileges (i.e. elevating her account, or giving her the password to a separate Admin account) or giving Mom an Admin account.
