CLS-DiskSpan (UltraARC replacement)

Sorry I'm bothering you.
It includes the new diskspan R3 (original Library) in CIU 3.0.0.0.1 beta and when displaying the search message for the disk, Setup.exe is terminated.
I don't know if it is because CIU has many features that require more from the system than a basic script.
I did the same tests using the Light Installer (very basic script) and there is hardly an error.
The request disk code in Light installer and CIU is exactly the same.

I have attached the examples where the installer closes when searching for the disk.
Run as is and search for part 1 and then for part 2 in folders when prompted (Most of the time the error occurs when searching for part 2).

@Razor12911, if you want to do tests I can send you the ciu beta source code.
The error I think is still in the callback, and I don't know if there is a solution for that.
