#1000 Certificate error

[Eitan Caspi]

Hello,
I downloaded and installed the latest version, 3.2.1, and installed in on the latest windows 10 build and updates, 64 bit.

The setup did not create any winodws start menu items, so I went to the folder of C:\Program Files (x86)\CalDavSynchronizer and run CalDavSynchronizer.vsto, which immidatly gave an error of:
Title: Installing office Customization
Body:

** Exception Text **

Sorry, my bad. It is not written, as far as I have seen, nor instructed in the setup - that the GUI for this app is inside Outlook, as a menu/tab. Only now found it.
