Cannot Change Compatibility Mode

Yes, lowering the UAC slider leaves your pc more unprotected, that's why I mentioned to only use it as an experienced user (...knowing your way around your pc...)

Does this problem occur only with the .exe in question btw?

You can always work around a problem through the register. I found this (below) on more than one site. Before starting I STRONGLY suggest you make a backup of the register . How? Type regedit in the searchbar in the startmenu and press enter, confirm UAC, click File -> Export, choose a filename and select where you want to save the exported .reg file to, select (dot) the All option under Export range , type in a name for the .reg file, and click on the Save button.
!The register is not a place to fool around if you don't exactly know what you're doing. You'll pay dearly if something goes wrong!
You can access the register by typing regedit in the search bar in Startmenu but you probably already know this.

All of the settings in the Compatibility tab can be set via the registry

- open REGEDIT
- goto "HKEY_CURRENT_USER\Software\Microsoft\WindowsNT\CurrentVersion\AppCompatFlags\Layers"
- create a new String Value
- name or rename it as the application full path e.g. " C:\Program Files\Internet Explorer\iexplore.exe "
- right click on the new String and select Modify
- type RUNASADMIN in the Value Data row; this will classify the program to be run as Administrator.
This allows you to bypass the GUI mode of settings editing. Instead you edit the settings by registry. And of course you can ignore the advanced
properties of the shortcut. Better launch the program in default
administrator mode ! :o;)

I've used it for Internet Explorer (iexplore.exe) that is part of the
system.

A desktop shortcut can be set to run as administrative mode.
But, if i launch the IE7 browser from a URL or Favorite link this won't
work and Windows Vista will run it in User Mode... UNLESS I'VE CHANGED
THOSE OPTIONS WITH REGEDIT. To run regedit go to Start Menu and then
"Run..." type REGEDIT.EXE or REGEDIT.

Other Options and some examples .
Always in the key called HKEY_CURRENT_USER\Software\Microsoft\Windows
NT\CurrentVersion\AppCompatFlags\Layers u can add more variables:

RUNASADMIN: i've just told, Run That Program As Administrator
:rolleyes:;
256COLOR: Run the program in 256 colors;
640X480: add this value to run a game or other application in a lower
res;
DISABLETHEMES: add it to disable Windows visual themes 4 that app;
DISABLEDWM: Disabled desktop composition;
HIGHDPIAWARE: Disable display scaling on high DPI settings;

ELEVATECREATEPROCESS: i dunno, unknown function. :confused:

COMPATIBILITY VALUES (don't use'em together, only one per app !):
WIN95: to add Windows 95 compatibilty mode;
WIN98: to add Windows Millennium or 98 compatibility mode;
NT4SP5: NT 4.0 Service Pack Five Com Mode;
WIN2000: type it to add Windows 2K compatibility mode;
WINXPSP2: Windows XP Service Pack 2 compatibility mode;
WINSRV03SP1: Windows Server 2003 SP 1 com mode.

Windows also creates these option strings when you change Compatibilty
Settings in the properties of the selected executable (GUI mode, Not
Regedit Mode).
