Few installs failing on 1.8.2 but not 1.8.0

I am having some installations (both from ISOs and from EXEs) failing when I click the `Install` button with the generic: "The installation was either canceled or failed." I'm not exactly sure what the issue is yet as I've seen it with just a small number of different titles that don't seem to have anything in common. I've attempted to rename folders, files, etc and it doesn't change the behavior. I've even completely wiped the add-on and library. In the case of ISO files it'll mount the ISO for a split second before ejecting it and presenting the error. If I click the `More` menu and then `Install` it runs the setup fine but then LocalLibrary won't detect the game was installed once it completes. I went back versions of LocalLibrary until the error stopped, seems 1.8.0 and earlier doesn't have this issue. My best guess is something is stopping the installer from running in specific situations and the installation monitor sees it as a failure. I edited where the file was pointing to one that doesn't exist (eg renaming `setup.exe` to `install.exe` in the Actions menu) and I get the following error. <img width="389" height="146" alt="Image" src="https://github.com/user-attachments/assets/2681739a-6a13-4b96-b1e4-9c880a9f2430" /> When I select the correct file I get the same fail error. Interestingly.. this specific example isn't an ISO, it's just a setup.exe. So maybe it is falsely seeing it as an ISO when it isn't? Though I don't know why an ISO install would fall as well. Slightly related... I can open a new issue/feature request for this if you like. But since the `More>Install` works just fine except for LocalLibrary not switching from `Install` to `Play` automatically would it be possible to add an option under `More` for something like `Manually Installed` where it'll skip the install step and give the popup to select the game exe? This would also help if you already installed the game before LocalLibrary adds it and you want to link it for easier management in the future.
