Newbie Trying to Set AppFolder

[rodscher]

Hi, all. I'm trying to reset the default installation folder for an app, depending on whether or not the user has already installed a previous version. I'm able to locate the EXE file itself, but then I'm stumped; how do I change the default app folder to reflect the location of that (previously installed) file?

Here's what I'm using to find the file (mostly snagged from someone else's previous post on a related subject - thanks!):

for i,v in tbDrives do
	if Drive.GetType(v) == DRIVE_FIXED then
		tbFile = File.Find(v, "MyApp.exe", true, false, nil, nil);
		if not tbFile then
		else
			-- SET THE DEFAULT INSTALL FOLDER HERE!
			break
           end
     end
end

I figure I could also do it by checking the Registry to find the app's current location, but I didn't get anywhere with that, either.

Seems simple enough, so I must just not be understanding something about syntax, variables, etc. (Or else I need sleep.)

Thanks for any help you can offer!

Try something like this:

for i,v in tbDrives do
	if Drive.GetType(v) == DRIVE_FIXED then
		tbFile = File.Find(v, "MyApp.exe", true, false, nil, nil);
		if not tbFile then
		
		else
			Paths = String.SplitPath(tbFile[1]);	
			SessionVar.Set("%AppFolder%", Paths.Drive..Paths.Folder);		
        end
     end
end
