On the Storefront server:

• Go to C:\inetpub\wwwroot\Citrix\Store\ (Where Store is the name of affected Store)
• Open web.config file with notepad
• Search for a string: RequireLaunchReference
• Change the value to "ON" (requireLaunchReference="on")
• Save to config file
• If you have multiple Storefront servers in the group - propagate the change.

You can also use Powershell cmdlets.

You can check if the RequireLaunchReference setting is set to TRUE or FALSE.

$storeservice = Get-STFStoreService
Get-STFStoreLaunchOptions -StoreService $storeservice

In case of multiple stores you can use foreach loop:

$storeservice = Get-STFStoreService
Foreach ($stores in $storeservice) {Write-Host "StoreService : " $stores.VirtualPath;  Get-STFStoreLaunchOptions -StoreService $stores}

If the change is required (RequireLaunchReference set to FALSE), you can change the value, example:

$storeserviceToChange = Get-STFStoreService -VirtualPath '/Citrix/Store'
Set-STFStoreLaunchOptions $storeserviceToChange -RequireLaunchReference $True

** /Citrix/Store is the example of VirtualPath, replace 'Store' with he name of the affected Store.
