I have a similar situation (although the update tool is not automatic, users
launch it when they want an update or to check for an update), and like
someone else suggested I find the best solution is to _skip_ the middle man.

Don't write to a file. Get the version information directly from your
program.

Since your update tool clearly knows the install location of your program,
have the update program call your program with some "--version" flag and
read from stdout what version the program itself reports. With QProcess,
running a application and reading all of it's stdout is like a two liner.

If you have trouble because your application is built with subsystem:windows
and doesn't have the ability to write to stdout, there are multiple
workarounds, including a project I posted:
http://code.google.com/p/dualsubsystem/

Why would you want to trust the accuracy and up-to-date status of a file
sitting on a customers hard drive anyway?
