I have a Windows 7 x64 with PowerShell 5.0 and IIS7.

IIS Manager crashes when I try to open the node for my server with the following error with the following error:


IIS Manager terminated unexpectedly.

I found a couple pages on the web link1 and link2. I tried installing the Upgrade Readiness Tool and rebooted, but it didn't help. Any ideas?

  • The first thing you should do is add/remove IIS. Why are you running a tool to help solve Windows Update problems? – Ramhound Jul 15 '16 at 20:42
  • I am running the tool because it fixed the user's problem in link2. – Eric Jul 15 '16 at 20:47
  • You are not running it on a AppFabric server nor as you using Powershell 4.0, the problem in your links, are not cause by the samething. – Ramhound Jul 15 '16 at 20:50
  • Removed iis, rebooted, added it back. Same problem. The error message doesn't mention AppFabric, but it does mention Powershell. I have websites that use AppFabric. – Eric Jul 15 '16 at 20:59
  • downgrade PS from 5 to 4, does it fix it? – magicandre1981 Jul 16 '16 at 7:03
