Is there a MSI command line switch to prevent the MSI from opening the survey website on uninstall? We have a client that wants to remove the software from a high number of machines and doesn't want all the users being prompted. Why does the survey not honour the silent MSI run?

Hello and welcome to our forums,

Thank you for using Advanced Installer.

This is our current implementation. I've created a ticket in our bug tracking system and so we analyze our current implementation and maybe we will consider not displaying the uninstall reason form during a silent uninstall process. I agree with you that this defeats the purpose of an unattended process.

In the meantime as a workaround, you can proceed like this:
1. go to "Custom Actions" page and add a new "Set installer property" custom action with sequence like this:

• Property: AI_IA_UNINSTALL_REASON
  Value: ""
  Condition: UILevel = "2" AND REMOVE = "ALL"

2. schedule the action under the "Install Execution Stage" just before "Searches" action group
3. rebuild and test the silent uninstall scenario

All the best,
Daniel

Unfortunately that doesn't solve the uninstall of the software currently out there on 3500 endpoints.

We are actually turning off the survey all together in an upcoming release so the client will have to "update" to that before running the uninstall unfortunately.

Hello,

If you already deployed the setup on customer network, then to suppress the uninstall survey form you can set from command line (at uninstall time) the "AI_IA_UNINSTALL_REASON" property to empty string.

For instance you can use an uninstall command line like this or like this: All the best,
