Oblivion - UAC messages and Visual Glitches (2 separate issues)

Hello again!

Thanks to guidance from online communities, including this forum, I now have Oblivion installed and working with all of my mods (there really aren't that many mods in my list at this time). HOWEVER, I am still experiencing a few issues that I am unable to figure out on my own, and I was hoping this forum could help.

THE ISSUE #1
This issue is entirely due to my inability to understand UAC. I can't seem to get the UAC prompt to go away upon startup of this game, no matter which icon (of the several possible shortcuts or the .exe in the game folder) I click on to start the game, or if I use the built-in launcher of OBMM.

I'd prefer not to disable UAC entirely (which is the only way I have succeeded in eliminating the UAC prompts thus far). Oddly, I have set nothing in the OBMM properties to dissuade UAC, and it launches without interruption. I have this installed in the same folder as the Oblivion.exe (C:\Games\Oblivion).

I have gone to the .exe in the game folder, and right click to set various conditions in Properties, as suggested by various online sources. This is what I have set, thus far:
-Compatibility Tab-Disable visual themes/Disable desktop composition/Run this program as an administrator/Changed settings for all users

-Security Tab-Full Control/Modify/Read&execute/Read/Write ; All Users Listed

Also, on the Shortcut Icons:
-Shortcut Tabs-Advanced Button-Run as administrator (This always resets itself to unchecked)

THE ISSUE #2
It's very hard to describe what I am seeing. I get one set of glitches when I enable V.Sync, and another when I disable it or run it in windowed mode. It's kind of like the 'tearing' described in the TweakGuides that was recommended in the above pinned troubleshooting topic, kinda.

If I enable V.Sync, (which was my former setting on my old XP system) I get very rare random flashes of electric-blue OR grey where a texture ought to envelop the mesh of a certain object/wall, AND I get random grey/goldenrod flashes like diagonal creases reminiscent of 'tearing', especially when I am standing still near flickering light. Also, tho not a glitch, I do notice less than smooth running of the Map movie in the main menu.

If I disable V.Sync or run the game in windowed mode (a full screen window), the issues listed above seem to be eliminated; however, a new sort of 'tearing' manifests in the game menus (not the UI). This looks more like the 'tearing' described in the TweakGuides document, as it is horizontally aligned, and seemingly shifted. Also, for comparison, the Map movie at the main menu runs smooth and evenly.

If I can't eliminate the visual glitch, I will play it with V.Sync off, as that seems to leave the world experience of the game alone; tho, of course, I'd like to figure out how to be 'artifact' free.

TROUBLESHOOTING
HISTORY - ISSUE #2
I include the following so you can know what I have considered/tried thus far...
I looked at the troubleshooting topic pinned above and I think I have done due diligence? This is numbered according to the pinned troubleshooting topic. Please correct/redirect me if I have missed something... Or if there is a way to verify an unknown/uncertain variable...

1. Update drivers: When I go to device manager, and right click to update driver, they all say they are up to date.
2. Correct drivers?: How do I know/how can I tell for sure?
3. Patch Game: GOTY comes fully patched to 1.2.0416
4. Windows Update: says," Windows is Up to Date"
5. Update DirectX Files: I installed 9.0c when I installed the game. How can I tell if I need to update?
6. DirectX 10/11: I believe I have these, but since Oblivion is meant to use DirectX9, this should be a non issue.
7. Game Settings: I adjusted them to desired adequate levels. I did not touch my .ini file (makes me nervous). I also referenced TweakGuides.com for guidance, by reading the guide for Oblivion, as well as the gamer's graphics and display settings guide.
8. Video Card Control Panel: I did not alter anything; nothing is competing.
9. Display Settings: A-ok
10. Antivirus: avast! is a non-issue. No change if on/off/gamers mode.
11. Game Managers: n/a
12. secuROM: I think that's also n/a
13. Overclocking: n/a (I am not intentionally doing this, and doubt it is an issue)
14. Permissions: I think these are not an issue with regards to my visual glitches. I am still reading about and trying to understand these and UAC for my other issue with the game.
15: Game Mods: Same issues pre-modded and post-modded; not the cause.
16. Compatibility Mode: No difference either way.
17. Known issues: I can't find my exact issue, but I find similar, with no resolutions.
18. Game forums: I've been visiting those too (for years).
19. Tech Support: Not tried, I don't expect it'll help (Win7 not officially supported).
20. Search: I have. Maybe I am choosing poor key words? I have read much relative and helpful info, but I have yet to find my particular issue/answer.
a- Overclocking: Not something I have ever knowingly attempted.
b- Overheating: I doubt it. Lotsa fans. New rig. Overqualified hardware.
c- Case Cooling: again, I doubt it. Lotsa fans with washable filters.
d- Power Supply: again, I doubt it. Overqualified and brand new.
# Game Compatibility List: Oblivion did not make the initial list, but was mentioned later in the topic (several times, including my particular edition), and many gamers on other forums have Oblivion working fine on Windows7x64.

- check your CCC (- via right-click on desktop)

- what is listed under Information/Software..?
- it should show which version AMD/Ati gfx driver you have installed..

I don't get problems with UAC - are you set up as the Administrator account..?

BugMeister
Thanks for your reply. Yes, I am set up as the Administrator account. In fact, it is the only account on the machine. Any other settings I ought to check or ideas I can try? ~Nom

Sygnus21, thanks muchly for your response!

The files/game is installed in C:/Games/Oblivion.

I did not create an 'Everyone' category as directed in the tutorial, as I only want to free up the game for myself on this one computer. I have four 'names'/accounts listed under the security tab (but I recall only making one, so I assume Windows made the others by default/for system requirement): Authenticated Users, SYSTEM, Administrators(me), and Users(me). I eventually gave permissions to all four names/accounts on the list, to the .exe, the launcher, the Oblivion folder, and then to the Games folder.

I gave permissions to the .exe and launcher (previously), then (after your response) to the Oblivion folder, and the Games folder; I was about to for the C: directory, but was advised by the system that giving permission to the 'root directory' may have unforeseen repercussions; so I canceled out. While poking into the security tab of the C: folder, I saw that I already have full permission for the SYSTEM and the Admin account. I am using the Admin account...(Or so I thought).

I tested to see if the game would skip the UAC prompt after altering permissions to each item/.exe/folder change; after having all listed accounts/users marked with full permission on the launcher, the .exe, the Oblivion folder and the Games folder; I am still receiving UAC prompts.

Do I truly need to make an 'Everyone' listing to get the desired UAC interaction? Or is there something else I am missing? Like a proper way to log in as an administrator, perhaps? [I checked my User Accounts Page, and I am listed there by my name, and the word Administrator underneath... I assume that means I AM in fact using/logged-in as the Administrator...]

Insights Welcome...

P.S. I have the OblivionModManager(OBMM) installed to C:/Games/Oblivion ; the same location as the .exe and the launcher... OBMM will initiate without triggering a UAC prompt. It has the same permissions as I have given to the .exe, the launcher, and the two folders they are contained in (under C:/). Might this mean that it isn't a permissions issue after all?

P.P.S. I apparently also have a guest account that was created by default. It has never been logged into.
