Hello,

I want to change a registry value for a AppVPackage by using below commands, but it’s not working. Any idea why?

```
$AppVName = Get-AppvClientPackage -PackageId ef1af223-8cc4-4622-a8c2-cd5af4308d05
$AppVName
Start-AppvVirtualProcess -AppvClientObject $AppVName cmd.exe
set-itemproperty HKCU:\Software\FRS\FiRE\Defaults JREPath C:\Program Files (x86)\Java\jre1.8.0_231
```

I have no experience with this. I guess you have to run it under the cmd process. Or use reg.exe instead.

```
Start-AppvVirtualProcess -AppvClientObject $AppVName cmd.exe '/c powershell set-itemproperty HKCU:\Software\FRS\FiRE\Defaults JREPath "C:\Program Files (x86)\Java\jre1.8.0_231"'
```

Or this? I’m not sure if the argumentlist can be an array or a space seperated string, or maybe both work, if it’s like start-process:

```
Start-AppvVirtualProcess -AppvClientObject $AppVName -filepath powershell -argumentlist set-itemproperty, HKCU:\Software\FRS\FiRE\Defaults, JREPath, "C:\Program Files (x86)\Java\jre1.8.0_231"
```

```
set-itemproperty HKCU:\Software\FRS\FiRE\Defaults JREPath C:\Program Files (x86)\Java\jre1.8.0_231
```

The immediate problem is that the spaces in **C:\Program Files (x86)\Java\jre1.8.0\_231** are causing PowerShell to be unable to interpret your input parameters. You should always wrap paths in quotes so that the shell doesn’t parse special characters and spaces:

```
set-itemproperty 'HKCU:\Software\FRS\FiRE\Defaults' JREPath 'C:\Program Files (x86)\Java\jre1.8.0_231'
```

Also, for the sake of safety when editing the registry, you should specify each parameter explicitly rather than using the shorthand method. Every [tutorial](https://4sysops.com/archives/interacting-with-the-registry-in-powershell/) about [registry editing](https://blog.netwrix.com/2018/09/11/how-to-get-edit-create-and-delete-registry-keys-with-powershell/) with [PowerShell](https://docs.microsoft.com/en-us/powershell/scripting/samples/working-with-registry-entries?view=powershell-7), and the [documentation for Set-ItemProperty](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.management/set-itemproperty?view=powershell-7), shows the full parameter names being typed out.

```
Set-ItemProperty -Path 'HKCU:\Software\FRS\FiRE\Defaults' -Name 'JREPath' -Value 'C:\Program Files (x86)\Java\jre1.8.0_231'
```

It pays to be careful with the registry.

Note that set-itemproperty has a -Type parameter with registry paths, but it’s not documented in an obvious place.

Ok, the below ‘Set-ItemProperty’ command is working, but the registry change is not done in the registry for the AppVpackage rather in the normal window registry. How can I load the virtual registry appV package before the ‘Set-ItemProperty’ command?

I think this is what you’re looking for: [How to Configure the App-V Client Registry Settings by Using the Command Line](https://docs.microsoft.com/en-us/microsoft-desktop-optimization-pack/appv-v4/how-to-configure-the-app-v-client-registry-settings-by-using-the-command-line), and specifically this part:

> **Important** On a 64-bit computer, the keys and values described in the following sections will be under HKEY\_LOCAL\_MACHINE\SOFTWARE\Wow6432Node\Microsoft\SoftGrid\4.5\Client

I think the registry subkeys for the AppV client will be listed under that path, but I don't have an AppV environment to check it. You'll have to look through your own registry to verify.
