Same command works with enter-pssession but not invoke-command

Question

I'm trying to run an executable remotely with powershell. Right now I'm trying to install Office 2013 SP1, but in the past I've had the same issue with other executables.
The command I'm running is as follows:
Invoke-Command -computername computer01 -scriptBlock {C:\windows\Temp\proplussp2013-kb2817430-fullfile-x86-en-us.exe /quiet}
It finishes almost immediately, returning no result, having not installed anything.
However, if I do the following, it works just fine:
Enter-PSSession computer01
C:\windows\Temp\proplussp2013-kb2817430-fullfile-x86-en-us.exe /quiet
Any idea what my problem with Invoke-Command is?

Answer 1

I did an Enter-PSSession, then ran the command using start-process. It hangs indefinitely. I did have to change the command a little, because I couldn't just put the whole command in quotes - that gave me an error saying the file wasn't found. I separated
it into -filepath and -argumentlist params. Below is what I ran:
Enter-PsSession -computername computer01
start-process -filepath "C:\windows\Temp\proplussp2013-kb2817430-fullfile-x86-en-us.exe" -argumentlist "/quiet"
This resulted in the session hanging indefinitely. So here is where I'm at:
Enter-PsSession then running the command works
Invoke-command with the command immediately finishes, with no output and the program doesn't actually install
Enter-PsSession then running start-process hangs indefinitely
Invoke-Command plus start-process hangs indefinitely
I was curious to see if this held true with other programs, so I tried installing a program from HP with a silent switch and got identical behavior throughout all four scenarios listed above. 
Turning off on-access A/V protection made no difference.
Finally, regarding mjolinor's question about the program running in non-interactive environments: to the best of my knowledge the program can - but I'm not positive. I would assume, however, that invoke-command would build the same sort of environment as
Enter-PsSession does, and it works there.
