As I said, this works fine for me. If I allow the rights elevation, the 
other application is started, while the first one continues to work just 
fine. If I refuse the rights elevation, the other application is not 
started, and an OS Runtime Error is raised: 1223 -- "The Operation was 
canceled by the user", which can be Ignored, after which the original 
application continues to run without any issues.

But, if you don't need asynchronous behavior, as indicated above, you could 
try using the ShellExecuteA() API function instead, and see if this works 
better for you.

Can you post some actual code that produces the error? What error is raised? 
What Xbase++ version do you use? Have you tried without UAC? Have you tried 
to start a different application (that requires rights elevation)? Have you 
tried it on a different computer?

The problem is probably not RunShell(), but something else you are doing.
