Problem on Windows writing an XML file (permissions?)

[undavide]

Hello,
I've a script with an initialize function. The simplify flowchart is:

init()
Is there an XML file in this position?
- YES: read data and do stuff
- NO: write a default XML file then call recursively init()

Apparently I've no problems on Mac - but I've been reported stack overrun errors on Windows because no XML is found and, I assume, no XML can be written to disc. Why is so, I can't say - I'm afraid permissions are the problem.

Given that my script installs (via Adobe Extension Manager) in Photoshop CS6/Presets/Scripts/myFolder (and I do not install a default xml, but the script writes the XML itself in the same folder), what's the problem with Windows?

Would a different folder for the XML (such as some myDocuments or userData) solve the permission problem in your experience?

Thanks in advance!

The reason is that Extension Manager must be run as Administrator on Windows 7/Vista. As a normal user you do not have write access to these folders.
Putting the xml in a user folder should work.

Paul, I'm afraid I can't get why Extension Manager (EM) may be the culprit - possibly I didn't explain myself properly: the only file that EM is supposed to install is the jsx, and it does it successfully.
Then, in turn, the jsx (when launched in PS) creates the XML file - so possibly (this is my interpretation) it is the User (running PS) that doesn't run PS as Admin - so that the jsx has not the privileges to create a file somewhere.
Which may make sense, but it's damn annoying.

Putting the xml in a user folder should work.

Hopefully! I'll give this a try (userData may be an option in order to keep the user's main folders clean)
Thanks,

Panels/Extentions can not be installed without installing with Administrator. The normal user ID does not have write access to anything above C:\Program Files or C:\Program Files (x86)
Except for CS6 where they have altered the permissions for the following folder..
C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)\Presets\Deco
You could run a VB script to amend the permissions on a folder durring the first run, but inform the user they need to run Photoshop as Administrator just the once to complete the installation.

Here is a snippet that I've used before to set permissions..

Code: Select allvar newFolder =  Folder(app.path + '/' + localize("$$$/ScriptingSupport/InstalledScripts=Presets/Scripts")+"/myNewFolder");
var SCRIPTS_FOLDER =  decodeURI(app.path + '/' + localize("$$$/ScriptingSupport/InstalledScripts=Presets/Scripts"));
var testFile = new File(SCRIPTS_FOLDER + "/SecurityTest.txt");
testFile.open("w");
testFile.close();
if(!testFile.exists){
   alert("You must run Photoshop as Administrator to run this install script\rRight click on Photoshop and select Run as administrator");
    return;
}
testFile.remove();
if(!newFolder.exists) newFolder.create();
if($.os.match(/windows/gi)){
var mybat =File(Folder.temp+"/folderperms.bat");
mybat.open("w");
mybat.writeln('echo Y|cacls "'+decodeURI(newFolder.fsName)+'" /t /c /g everyone:F');
mybat.close();
mybat.execute();
}
