Worked for me. Thanks bro!
Here’s exactly what I did:
Uninstalled the A350.
Reinstalled the A350.
When it got stuck, I went to the folder: C:\Users\matth\AppData\Local\iniManager\app-2.4.5\resources\app\temp
Copied the file "1192-full" to the root of C:\ and extracted it there. This avoids the long path error.
Moved the extracted folder back to: C:\Users\matth\AppData\Local\iniManager\app-2.4.5\resources\app\temp
Aborted the installation on iniManager.
Closed and relaunched the iniManager.
Tried installing again — this time it worked.
