I just uninstalled my old PDFCreator, restarted my computer, and ran the setup for v2.3.2. It ran briefly then displayed a window saying I needed to restart the computer to complete the installation. I thought that was strange because it was only about 10 seconds since I started it, and I had not seen any of the usual dialogs. So I restarted, and waited, and nothing has happened.
It is not in my Programs and Features.
Running Win10 Home 64bit.
I decided to post this here rather than trying to run it again.
