batch will not execute if included with installer, or compiled into exe, or called from an exe

This seems odd to me and I am not sure what is causing it.  

I have a batch that adds the following registry string

reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /v "%ProgramFiles%(x86)\bquest\bq.exe" /t REG_SZ /d "WINXPSP2 RUNASADMIN" /f >NUL

All it does it make the shortcut with admin privilages for the user.  

Problem:  This is one script among many in my larger batch file I will issue to my gaming community.  When compiled into exe it does not work.  If I make it a .bat it works, but if I call it from an exe file it does not work.  So I made an installer, which has the.bat as an include and launches it first before anything...and it does not work.  It only works as a bat file executed directly, nothing else can call on it.  

I have to get this working, it can be a .bat file i dont care, but it has to at least allow me to include it in the installer.  

What could cause this?  Some sort of windows permissions?

Get procmon from Microsoft, run it up.  Run your installation.  See which part it is failing on.  It will tell you the call or the file it it trying to get to.  You can filter on processes to reduce the amount of output - procmon monitors all processes.

Maybe "will not execute" was poor choice of words.  If I pause the batch, then add to winrar, then execute, it says "the operation completed successfully" for each regedit line item.  Its just not there when I open registery.  So there is no error messages.  However it is there if I exec bat outside of the installer.  Bizarr, I will still try your utility when I get a chance later

Is it asking for input, timing out and exiting incorrectly?

No to all.  In fact is seems to run normal.  It just does not edit the registry if compiled in winrar, or bat to exe.  Its got to have something to do with windows7.  I ran the .exe on windows xp and it works.  
I also tried not using batch at all, instead using .reg script, and the same thing happened.  

Is there something in windows 7 that would block a program from editing registry?

Did you try this on XP32 or XP64?  Your regedit will only make sense on XP64.

Yes - Windows Vista and Windows 7 have added security features. It is basically to stop viruses messing up your registry.  That was the good side.  The bad side is genuine stuff is difficult to install.

Is your executable digitally signed?  You have to create a strong name key (.snk file) and embed it into your executable.  Could give that a try.  If that fails,  it is a big trawl through the internet to figure out how to get around it.

Sorry I can't help any further.

The other alternative is to tell the user to run the command manually with apologies that MS security won't allow you to do it automatically.  It is just another batch file and most users will be quite happy to do it.
