Empty Command Line Parameters Merged Together

[leeroy]

Hi, we are running an Inline Powershell Script and passing in parameters, but when a user passes in empty parameters on the command line the values are munged together in an unusual way.

Command:

Code: Select all

msiexec.exe /i installer.msi /qn HP_URL="" IDS="123456"

Powershell Inline Script:

Code: Select all

Parameter values: 
-cfPath "[APPDIR]/Config.json" -tkURL [TK_URL] -hpURL [HP_URL] -ids [IDS]

Params (cfPath and tkURL are calculated from other scripts): :

Code: Select all

Param($cfPath , $tkURL , $hpURL , $ids )
$hpURL = "IDS=123456" <-- This has been munged together
$ids = ""

However if HP_URL is provided a value other then empty string it works fine.

Hello,

If possible, could you please create a sample project that reproduces this and forward it to me?

I'm afraid I wasn't quite able to reproduce this on my end.

Best regards,

Hi Catalin,

I made a simple install. After you build it just run it like the following.

Code: Select all

msiexec.exe /i paramTester.msi /qn BAR="" BAZ="2041860278"

Output:


The baz param ends up in the bar param.

Hello,

I have tested this using the AIP file you provided, but I'm afraid I'm not able to reproduce this:

Hi Catalin,

I wonder if you ran this in a regular command prompt, not PowerShell. I believe this only occurs in PowerShell.

Kind regards,

Hello Lee,

There shouldn't be any differences if you run the setup from a PowerShell or a CMD shell.

I have tested this with PowerShell and the results are the same:
