How to set access rights in folders with the Qt Installer Framework
stvokr last edited by stvokr
I'm trying to use the Installer Framework on Windows to install my app to "C:\Program Files\My Company\MyApp".
And my App uses some config files (read and write) in "C:\ProgramData\My Company\MyApp", so I want to create this folder and set the access rights.
No I have the problem, that the folder should remain, even after uninstalling the software.
This is working, but the folder is deleted during uninstall.
var dataDir = "C:\ProgramData\My Company\MyApp"; component.addOperation( "Mkdir", dataDir );
This does not work in any configuration, I even tried without spaces in the folder name.
var dataDir = "C:\ProgramData\My Company\MyApp"; component.addOperation( "Execute", "mkdir " + dataDir, "UNDOEXECUTE" ); // or this one component.addOperation( "Execute", "mkdir", dataDir, "UNDOEXECUTE" );
I get the following errors:
- Cannot start: "mkdir C:\ProgramData\My Company\MyApp": Process Failed to start: No such file or directory
- Cannot start: "mkdir C:\ProgramData\My_Company\MyApp": Process Failed to start: No such file or directory
I also tried a batch file to call mkdir, and this is working. But I want to know if there is a better way from inside the installer to create a folder with spaces in the folder name, which is not beeing deleted during uninstall?

I found part of a solution myself.
This is working when the folder name does not contain spaces.
installer.executeDetached( "cmd", "/C mkdir C:\\ProgramData\\My_Company\\MyApp", "@TargetDir@" );
A solution with spaces is still required.
@stvokr You need to put the path into "" to make sure it works with paths containing spaces.
installer.executeDetached( "cmd", "/C mkdir \"C:\\ProgramData\\My_Company\\MyApp\"", "@TargetDir@" );
@jsulm I forgot to mention, that I already tried masking the quotes. That did not work.
@stvokr According to https://doc.qt.io/qtinstallerframework/scripting-installer.html#executeDetached-method it is actually not needed: "Windows: Arguments that contain spaces are wrapped in quotes.".
There is something you're doing wrongly I think. Take a look at this:
boolean executeDetached(string program, stringlist arguments = undefined, string workingDirectory = "")
The parameters must be passed as a string list. You're passing all parameters as one string.
@jsulm Hi, if I pass the parameters a string list
installer.executeDetached( "cmd", "/C", "mkdir", "My_Complany", "C:\\ProgramData\\" ) );
the InstallationLog.txt tells me,
"run application as detached process: "cmd" ("/C") "mkdir"
and that the operation has returned false. So the given parameter "My_Company" has somehow not been passed.
So, finally, I got a solution (even 2 solutions):
installer.executeDetached( "cmd", ["/C", "mkdir", "C:\\ProgramData\\My Company\\MyApp"], "C:\\ProgramData" );
With this trick even the addOperation() function works fine:
component.addOperation( "Execute", "cmd", ["/C", "mkdir", C:\\ProgramData\\My Company\\MyApp"] );
I think this is closed.
