I am using image template to creat the image and during creation of image template in th custamizations section. User's image

I have added powershell command for each set of commands below. I have added PowerShell command for each set of commands below. ****PowerShell command 1: **** New-Item -Type Directory -Path 'c:' -Name Java, invoke-webrequest -uri 'https://download.oracle.com/java/21/latest/jdk-21_windows-x64_bin.msi' -OutFile 'c:\temp\jdk-21_windows-x64_bin.msi', copy-item 'c:\temp\jdk-21_windows-x64_bin.msi' -Destination 'c:\temp' ****PowerShell Command 2: **** Start-Process -FilePath 'c:\temp\jdk-21_windows-x64_bin.msi' PowerShell command 3: Set the name and value of the environment variable $variableName = "JAVA_HOME" $variableValue = "C:\Program Files\Java\jdk-21\bin" Use [System.Environment]::SetEnvironmentVariable method to set the environment variable [System.Environment]::SetEnvironmentVariable($variableName, $variableValue, [System.EnvironmentVariableTarget]::Machine) Display a message indicating that the variable has been added Write-Host "Environment variable $variableName set to $variableValue" ****PowerShell command 4: **** New-Item -Type Directory -Path 'c:' -Name Python, invoke-webrequest -uri 'https://www.python.org/ftp/python/3.12.1/python-3.12.1-amd64.exe' -OutFile 'c:\temp\python-3.12.1-amd64.exe', copy-item 'c:\temp\python-3.12.1-amd64.exe' -Destination 'c:\temp' PowerShell command5: Start-Process -FilePath 'c:\temp\python-3.12.1-amd64.exei' I only see folders and .exe and MSI files copied in to the target VM but not executed .msi and .exe file that means only PowerShell command 1 and 4 worked but other commands not worked, Please suggest fix for this. I have not seen any error after image template got created. what could be the wrong with other commands You can see start process working inside VM which after I have tested User's image

Hello Varma

I modified it a little and tested it both locally and on an Image in my own gallery. I added some comment and explanation in the code, feel free to remove them or modify them to your liking :)
Don't hesitate to ask if you run into trouble with it.

#Creates the directory Java in C:
New-Item -ItemType Directory -Path "c:\Java" 

#Downloads the Java MSI file, I changed from Invoke-Webrequest to Invoke-RestMethod to ensure it waits for the download to complete before moving on
Invoke-RestMethod -uri "https://download.oracle.com/java/21/latest/jdk-21_windows-x64_bin.msi" -OutFile "c:\Java\jdk-21_windows-x64_bin.msi"

#Starts the installation, also added a Wait command here to ensure the installation is complete before moving on to next step, added /quiet to ensure no user interaction is needed.
Start-Process msiexec.exe -Wait -ArgumentList "/I c:\Java\jdk-21_windows-x64_bin.msi /quiet"

#Shortened the environmental command by using the command below, it creates a Environmental variable called #JAVA_HOME with the value of 'C:\Program Files\Java\jdk-21\bin'
#$Env:JAVA_HOME = 'C:\Program Files\Java\jdk-21\bin'

#Added back to set the variable to system instead of user
[System.Environment]::SetEnvironmentVariable("JAVA_HOME","C:\Program Files\Java\jdk-21\bin","Machine")

#Writes out the content of the environmental variable JAVA_HOME
Write-Host $Env:JAVA_HOME "has been added to the environmental variable JAVA_HOME"

#Creates the directory Python in C:
New-Item -ItemType Directory -Path "c:\Python"

#Same download procedure as with java but for Python
Invoke-RestMethod -uri "https://www.python.org/ftp/python/3.12.1/python-3.12.1-amd64.exe" -OutFile "c:\Python\python-3.12.1-amd64.exe"

#Same installation procedure as with java but EXE file instead and added /silent to ensure no user interaction is needed. Added the InstallAllUser=1 to ensure its installed for all users.
Start-Process -Wait -FilePath "c:\Python\python-3.12.1-amd64.exe" "/quiet InstallAllUsers=1 PrependPath=1"

Hope this is helpful Best Regards, Timmy Malmgren

Hi Timmy, I have used above commands as it is. Thank you, It seems to be Java got installed this time. however Python software and environment variable are not showing up. Pything file copied but not installed Please have a look at the below screenshot from VM. am I missing something in execution and verification inside VM?

and in local machine you can see below even path is there , it is prompting for path:

The command you are running manually have a " in the wrong place, thats why its not working.

The script however you are correct is not installing phyton and i think i know why, just don't have a solution yet.

The problem with Phyton is it places the installation files inside the user folder
"C:\Users\TimmyMalmgren\AppData\Local\Programs\Python\Python312"
As the installation is done by system it probably why i can see the installation in the "Event viewer" app logs, but no files. Normally applications have a parameter for installing for all users, unfortunaly that did not work for my Phyton installation either.

Start-Process -Wait -FilePath "c:\Python\python-3.12.1-amd64.exe" "/quiet InstallAllUsers=0 PrependPath=1"

I'm trying to see if i can find the MSI file (have some experience in MSI configuration) and open it up to see what variables are available :)

Kind regards Timmy

I think i got it working now

Modified the original post to. I'm waiting for my new image to complete its build (about 30min). But i got it working on a server logging in with several different users (manual proccess tough). The InstallAllUser should be 1 and not 0 as i originally did :)

. Added the InstallAllUser=1 to ensure its installed for all users.Start-Process -Wait -FilePath "c:\Python\python-3.12.1-amd64.exe" "/quiet InstallAllUsers=1 PrependPath=1"

It worked now for my new image, Phyton was installed on first logon :)
I modified the first post with the code, with the new code working for me now :)

Can just add i run it as a "powershell command", elevated as system

Hope this is helpful Best Regards, Timmy Malmgren

Replaced the env variable to a system based, my bad you had that specified in the beginning :), added it to the original code also. It will add it to the system variables usable by all users, sry for the confusion on my part :)

[System.Environment]::SetEnvironmentVariable("JAVA_HOME","C:\Program Files\Java\jdk-21\bin","Machine")

It looks like it removes it again when building the image, i suspect it is removed during sysprep when the images is generalized for build. I think you might have to add this after the VM is created. Are the servers domain joined or stand alone? Du you have any remote powershell possibility to the servers from a management server?

HI TImmy, It is not domain joined. I am not sure about remote powershell possibility to the servers? are you referring run book? if we have to add env variables again it becomes manual process as it includes creating vm and capturing vm
