Beta Release 15.1.33 is now available.
The download link seems to point to 15.1.29.
At least I have installed 15.1.29 and after starting the setup file I am only offered "Repair" as an option.
Oddly I had the same issue while connected to my Corp VPN. I disconnected and rebooted then launched Toad and it re-downloaded the 33 Beta which installed correctly.
@dirk.mika1 - Love the avatar! When I first started my professional career, I was working for GE designing ASICs and one of the old engineers gave me a wooden token with RTFM! engraved when I asked my second noob question. He became a good friend and seeing references like your avatar always brings back good memories, thx for brightening my Wed!
