Execute a variable in Powershell

Question

I have the following setup:

The last command is:
$("$($InstallationPath)\$($ApplicationId)\$($ApplicationId).exe install")

I want that to execute:

C:\Services\OmStudioAdministration\OmStudioAdministration.exe install

But it just prints the text of the command out. (Does not run the command.)

However if I copy that and run it, it does what I want:

How can I get it to run the command directly?
(So I don't have to copy and paste it in and run it.)

NOTE: In case it matters, I am planning to run this as an Octopus Deploy script.

Try This:

& {$InstallationPath\$ApplicationId\$ApplicationId.exe install}

Script Blocks are generally easier to run than character strings.

Replace your last line by this one:

cmd.exe /c "$installationpath\$ApplicationID.exe" install
