Hi Cappy.

Which version of Windows 7 are you using? Home Premium, Professional or Ultimate?

The reasons I'm asking are:

1. I rarely need install using "run as administrator". Look at the installer .exe and see if there is a small shield on it, if it is there, I have found I don't have to install as an administrator. This shield appears on almost all of my .exe files when it comes to installing on my computer, evem if they are inside a zip or rar file. My UAC is set at the second highest level that is the default and recommended setting by Microsoft. This one:

Default - Notify me only when programs try to make
changes to my computer

• Don't notify me when I make changes to Windows
  settings
  

Granted, I have Window 7 Professional 64bit and the user name I log in with is in the administrators group on the computer and that could be a difference if you are using Windows 7 Home Premium, which I believe is more strict for security reasons for basic computer users. I installed Windows 7 and chose my user name and was automatically placed in the administrator group.

2. I have FSX + Acceleration installed on a separate 500GB drive (this drive is for FSX only) and I am not having any troubles at all with FSX or any of my add-ons for it. I also do not have FSX.exe set to "run as administrator" under the compatibility tab. I did not select to "run as administrator" when I installed FSX and Acceleration either.

It's worth thinking about because everyone keeps saying this stuff about installing and running as an administrator and yet it doesn't apply to me and it never has. I wonder why? I never did anything to give my user any advance permissions and this is the third time I have installed Windows 7 on my computer (late last week). The second time was because I had a dual boot system I decided I didn't want. This last time because I had a nasty problem with my "C:" drive requiring me to buy a new drive. This situation has always been this way including the first two installations of Windows 7 Professional 64bit.
