PowerShell 7.1.0-preview4 x64 executable removes PowerShell 7.0.2 and does not install preview4

[catthehacker]

Steps to reproduce

• Install PowerShell 7.1.0-preview3 (7.1.0.3) [PowerShell-7.1.0-preview.3-win-x64.msi]
• Install PowerShell 7.0.2 [PowerShell-7.0.2-win-x64.msi]
• Verify that both appear separately in C:\Program Files\PowerShell\
• Install PowerShell 7.1.0-preview4 (7.1.0.4) [PowerShell-7.1.0-preview.4-win-x64.msi]
• Verify C:\Program Files\PowerShell\7\ and C:\Program Files\PowerShell\7-preview\ again

Expected behavior

PowerShell Preview is updated to 7.1.0-preview4 and PowerShell 7.0.2 is not deleted.

Actual behavior

PowerShell 7.0.2 is being deleted from C:\Program Files\PowerShell\7\
PowerShell 7.1.0-preview4 is not installed (but its installation is added to registry)
PowerShell 7.1.0-preview3 is installed.

Additional info

This happened on my main PC (Windows 10 2004, build 19041.329) as well as I was able to reproduce it in VM with Windows 10 Insider Preview (build 20150.1000)
Also latest preview installation executable does not appear to have digital signature attached in comparison to the previous preview.
Something for @TravisEz13 I guess?

Will be fixed n #13036 I guess.

How to install preview-4 without .MSI?

Now I cannot use pwsh in Windows Terminal.

Might want to pull the notification of the new update that happens inside the preview 3. That's a bit of a big oopsie.

We are working to release preview 5 as quickly as possible. Feel free to file a feature request for the ability for us to disable the update notification functionality for a release, but I don't think it is viable at this time.

We already have such issue.
