Madcap flare cannot run and have errors after Win10 updates

Post by joemecha »

So Flare 2020 would not load and throws this error (I've already contacted support)

Code: Select all

at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor, Boolean& bNeedSecurityCheck)
   at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache, StackCrawlMark& stackMark)
   at System.Activator.CreateInstance[T]()
   at B3.WpfKit.WpfMain.<RunAsync>d__1`1.MoveNext()
So I tried to go reinstalling - but even the installers quit unexpectedly after the installers is progressing with "System Package .Net Core 3.1.100". I tried installing both with the company VPN on and the VPN off..

What could have gone wrong? Do I need to get a new WIN10 computer to install this? Registry issues don't seem to be it after checking with the Microsoft Troubleshooter.

I re-installed all .Net runtimes from 1.1 through 3.1, and my .Net Framework is up-to-date (.Net Framework 4.8)

Windows 10 version 20H2 (Build: 19042.1237)

Thanks! Appreciate any help.
