Hi,

QProcess supports accessing environment variables for the current process with environment(), setEnvironment() and QProcess::systemEnvironment().

To change the system's environment you probably have to change the registry, see: http://msdn2.microsoft.com/en-us/library/ms682653.aspx

Please take into account that in many corporate systems, users are not administrators and are not guaranteed to have read/write access in the HKLM where these keys are maintained (actually its HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Executive\Path). This had been the source of many a jolly issue where HKLM registry keys are being opened with KEY_ALL_ACCESS which subsequently fails (in other peoples apps i should add)

BTW the environment variable might not be set permanently. Probably the variable might me reset just after system function.
So i'm not sure whether it works or not.
