I am using the .NET PowerShell host. I have version 5 and 7 installed of PowerShell. When running:
$PSVersionTable.PSVersion
- it returns:
Major Minor Build Revision
5 1 18362 1110
How do I make it run version 7 of PowerShell?

3"I am using the .NET PowerShell host", I assume this means compiling against .NET Framework? PowerShell 7 runs on .NET Core >3.1, so you won't be able to use it from a .NET Framework host.Mathias R. Jessen– Mathias R. Jessen2020-11-06 12:45:56 +00:00Commented Nov 6, 2020 at 12:45

From Microsoft's documentation, you should be able to load a previous version of PowerShell.
Separate installation path and executable name
PowerShell 7 installs to a new directory, enabling side-by-side execution with Windows PowerShell 5.1.
Install locations by version:
Windows PowerShell 5.1: $env:WINDIR\System32\WindowsPowerShell\v1.0
PowerShell Core 6.x: $env:ProgramFiles\PowerShell\6
PowerShell 7: $env:ProgramFiles\PowerShell\7
The new location is added to your PATH allowing you to run both Windows PowerShell 5.1 and PowerShell 7. If you're migrating from PowerShell Core 6.x to PowerShell 7, PowerShell 6 is removed and the PATH replaced.
In Windows PowerShell, the PowerShell executable is named powershell.exe. In version 6 and above, the executable is named pwsh.exe. The new name makes it easy to support side-by-side execution of both versions.
Have a read of the webpage, using the link provided.

Powershell (Core) 7 is a different executable: pwsh.exe
powershell => Windows PowerShell (latest: v5.1)
pwsh => PowerShell Core (latest: v7)

From a console just do
where powershell.exe
-and-
where pwsh.exe
you should obtain:
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
-and-
C:\APL\Microsoft\PowerShell64\pwsh.exe
then you can call the .exe(s) direcly...
to bypass any issues with .cmd(s)/.bat(s)/.lnk(s)/alias/hijackers/etc. etc.
