CheckFolderVersion

[jdrescher]

Hello!!

We have the following problem: We build a patch with VP3 which doesn´t work, because the function CheckFolderVersion(...) always returns 0. If we load the project with VP2, everything works.
Then we created a new project and the same problem appeared.
Here is a part of our code we use:

if not g_InstalledVersion then
	local MainKey = HKEY_LOCAL_MACHINE;
	local SubKey = SessionVar.Expand("Software\\Test");
	local ValueName = "HomeDirectory";
	local FolderPath = Registry.GetValue(MainKey, SubKey, ValueName);
	
	FolderPath = String.Concat(FolderPath, "\\bin");
	
	g_InstalledVersion = VisualPatch.CheckFolderVersion("%AppFolder%", FolderPath);
	if g_InstalledVersion then
		SessionVar.Set("%AppFolder%", FolderPath);
	end
end

Has this function (CheckFolderVersion) changed from VP2 to VP3 and how does it exactly work internal?

It now supports key files in subfolders automatically.

Try removing this line:

FolderPath = String.Concat(FolderPath, "\\bin");

You might also want to add some Debug.Print() or Dialog.Message() calls in there to see what those variables contain at run time.
