Excited by all the hype about Revit 2022.1, I just downloaded and installed it.
All went well apart from a couple of minor glitches:
1 - Parallel Installs
It decided that it could not install more than 33%, and sat there for ages before announcing that it had failed due to some other install going on. I have no idea what it was - some kind of system update, which required a reboot?
After rebooting the computer the install worked smoothly and quickly
2 - Trash the Installer
After completion, I decided to make a backup of the installer software and remove it from the hard-disk to save space - all 851 Mb of it.
Where the heck was it? I searched high and low - in the Download folder? In the Software folder that I had previously moved it to? No.
Eventually I found it in the 'Recycle Bin'. How did it get there?
I may be getting a bit forgetful, but I surely would know if I had somehow deleted the installer?
Could it be that Autodesk have built this "Self-Destruct" capability into the installer?
Or could it be some new trick that Windows 10 performs?
Conclusion
If you want to save time, reboot your computer, and then make a backup of before installing this update.
Now I look forward to testing the new features
