I have this working line:
ShellExec('',ExpandConstant('{app}\iush.exe'),'/ui "C:\Program Files (x86)\Myapp"', ' ', SW_HIDE, ewWaitUntilTerminated, errorCode)
But i want to replace the Program Files (x86) dirctory with its constant: "C:\Program Files (x86)\Myapp"
>> {pf32}\Myapp
Then It would like:
ShellExec('',ExpandConstant('{app}\iush.exe'),'/ui "{pf32}\Myapp"', ' ', SW_HIDE, ewWaitUntilTerminated, errorCode)
ShellExec('',ExpandConstant('{app}\iush.exe'),ExpandConstant('/ui "{pf32}\Myapp"'),'',SW_HIDE,ewWaitUntilTerminated,errorCode);
