When I first installed desktop version 21.2.30 it also didn’t run at all on the first three times I clicked on it. I checked the Task Manager and couldn’t see anything that looked like Manager running. I restarted my computer and then ran the install file again to repair the installation. After that on the first attempt at opening it I got the same error described by the original poster in this thread, and on the second attempt it opened fine.
I just upgraded Desktop version 20.2.24 to 20.2.96 (from memory, because I can no longer see)
2.24 worked fine, but I cannot open 2.96
My system is Windows 10, 64bit
OS Name: Microsoft Windows 10 Pro
OS Version: 10.0.19042 N/A Build 19042
Ok, so I did the upgrade and when I clicked the icon, the wait circle showed for a second, then nothing. No error message.
After reading previous posts, I decided to uninstall and start again.
This time, during the install, it prompted me to install Webview2 runtime and after that, it is now working.
So, to summarise, the update didn’t prompt me for Webview2, but the new install did?
All OK now, thanks for your follow up.
