Can't Run ACT! Pro v18: "Resolution of the dependency failed"

[pwk]

Just installed Pro v18, upgrading from v15, on Windows 10.

Every time I try to run it, I get the error msg: "Resolution of the dependency failed,  type = act.ui.actapplication", name =""." etc, etc.

There are loads of questions about this in the forums, going back for years (how on earth can a bug like this, even a multi-faceted bug, be allowed to continue for years?!)

I've tried everything I could find, nothing seems to work. Surely there's some way around this problem! I've uninstalled and reinstalled ... how can a clean install like this be so screwed up?!

AAAAAAAAAAAAHHHHHHHHHHHHHHHH!!!!! 

I can't even go back to ACT! 2013 now!

I tried, and now here's what I get:

I did the following: 

1. Uninstalled ACT using Revo Uninstaller, which runs the ACT installer then looks for left-over files/references and removes them
2. Ran a registry cleaner, and cleaned all problems I could find
3. Let Windows Update run ... I'm totally up to date.
4. Turned off User Account Control
5. Rebooted
6. Ran the ACT Pro 18 Installer as an Adminstrator
7. Installed ACT Pro 18
8. Tried to run it. ... same problem!

I reviewed http://kb.act.com/app/answers/detail/a_id/25865

I had already done everything on this list previously. 

I reviewed http://kb.act.com/app/answers/detail/a_id/38256/kw/Resolution%20of%20the%20dependency%20failed

This is more on the .NET stuff, the last two items from the previous file. I've already checked .NET; I'm running Windows 10, which includes .NET, and anyway the checks I did on .NET earlier told me .NET is fine.

I reviewed http://kb.act.com/app/answers/detail/a_id/37947/kw/Resolution%20of%20the%20dependency%20failed, which refers to the Microsoft .NET file called System.Xaml, which I replaced earlier. 

Can someone out there tell me how I can get ACT running!?

Also just installed Act! 18.1 Update 3; still the same problem!

Do what you haven't, uninstall ACT! and .NET and then reinstall.

I'm using Windows 10; there is no simple way to uninstall .NET.

.NET is built into the operating system. I'm not sure that it can be uninstalled without doing serious damage to the operating system, though I'm certainly willing to listen to/read something that explains how it can be done safely.

Did you try deleting your preferences?  There is a KB on how to do it.
