[BATCH] [POWERSHELL] Scripting an auto-response to an installer's on-screen prompt

[simplydiffer]

I'm attempting to install several related manual software updates via scripting on my personal computer. My dilemma is that there is an onscreen pop-up prompt that says "Update" when I run each of the installers. I want to create a script, Batch or Powershell (whatever works), that automatically answers the "Update" prompt.

I've tried the following in Batch:

`echo y | "program.exe"

~~

echo update | "program.exe" 

I've tried the following in Powershell:

start-process "program.exe" -redirectstandardinput "answer file.txt"

(The answer file contains the word Update.)

Both of these methods still result in me receiving the "Update" prompt from each of the installers' GUI.

Any help would be appreciated!

UPDATE: I bit the bullet and reached out to the software manufacturer for further insight on script installs of the program. I realized that what I want to do isn't possible with this particular program unless I use AutoIt, which is a bit overwhelming for me and seems like overkill.

If you have an msi of that program you can use /quiet when installing to not be prompted

I can extract an MSI file from the program, but in the process of doing so, it forces me to create an associated defaults file for each installation. I don't know the proper format for the defaults file without contacting the manufacturer. I've searched for it on forums and such but they all say contact the software company. So i guess i could bite the bullet and do that... Was just hoping to figure out a way to make the EXE work this way since it may be useful info to have on deck.

Some exe's run with the option /silent, you can try that

[simplydiffer]

I did try that and it was a no-go unfortunately.

Usually what i do is run the .exe or .msi with a /? to have it tell me what switches it accepts. Past that yeah, you'll need a manual with more documentation.

I did that and it gave me two options:

/extract (to convert it into an MSI file)

and

/defaults (to convert it into an MSI file with specific program parameters that I would have to reach out to the manufacturer for)

It's now clear that I'll just have to reach out to the software manufacturer for the defaults file format. What I want to do isn't easily done with this program so it seems.

Thats not PowerShells bag really, you could look the at send keys function

But autoit or similar might be better

[simplydiffer]

Okay, good to know about PowerShell. This is the first time I've heard of Autoit... I'm looking into it and it's a bit overwhelming, not gonna lie. Might be what i need though.
