Execute-Process issue - Newb Question

Mar 25, 2014 at 4:56 PM
First off, guys thanks so much for this tool. It has really simplified things for me in my organization where I'm typically the sole application packager for SCCM.

While I'm certainly no expert, I've been banging my head on this one. For some reason, when using Execute-Process to call an .exe, I'm getting the Windows Installer pop up window. I've looked over everything 4 times now at least and I'm sure I'm missing it, but it eludes me.

Attached is the pop-up I'm seeing, along with the log file for this particular deployment. Thanks in advance.

Hi there,
On a phone now so don't have a back tick on my keyboard, suffice to say I think you're just missing quotes around the /qn switch, you could try this or add normal quotes around it preceded by a back tick:
Execute-Process -FilePath "$dirFiles\anyconnect-2.5.exe" -Arguments '/S /v"/qn"' -WindowStyle Hidden

Sorry I'm late getting back and I appreciate you responding so quickly. I've tried modifying the quotes as you suggested, I even tried it by dropping the arguments altogether. Still no luck. At this point, I've acquired the MSI installer and I'm going to try this with another approach.

I've recently run into this issue as well...
Execute-Process -FilePath "LOTUS_Notesclient_853_WIN_EN_EVA.exe" -Arguments '/s /v" /qn"'
Has not been working for me. The installer requires the exact syntax of .exe /s /v"/qn". I've even tried doing .exe "/s /v/qn" which has worked for me on another .exe installer, but not for this one.

You might want to try backticking the quotes to tell Powershell to ignore them. By default, quotes mean "execute me". Try this:
Execute-Process -FilePath "LOTUS_Notesclient_853_WIN_EN_EVA.exe" -Arguments '/s /v`" /qn`"'

Thank you darktempest, I found the issue... I had the syntax correct, but it was being used on the wrong executable. The "support" site neglected to inform me that I would have to run this executable, wait for it to extract and cancel the install, go to the system temp folder and use those install files which would contain the "Setup.exe" that supported those install switches. Talk about jumping through hoops.
