Run a component only during first installation

hello,

I'm sorry if I am on the wrong section and sorry for my English.

I'm using Installshield 2016 and creating a msi. 

My situation:

I've created a component which add a file .cer in the INSTALLDIR in order to install it in trusted authority. To do this, I have a custom action played during Installation. At the end of the Execute Sequence I delete the certificat by using an other custom action.

My problem: When I do a repair in user mode (no admin rights), the certificat is added again but cannot be deleted because users don't have rights to suppress files in C:.

So I wonder if there is a possibility to use a condition so my component can be played ONLY during first Install.

Thanks for your help.

Hello

Use following condition for the custom action:
NOT Installed

The condition checks if it is already installed.
This allows to run only on the first installation

  • Thank you.

    The custom action is already setted as NOT Installed. I am not sure that the solution is here.
    I would like to set a condition on the component. - oussou75 2 years ago

As kitco mentioned - "NOT Installed" condition is one of the solutions.
In the InstallShield you can also add the .CER file to "Support Files" and call it using [SUPPORTDIR] property.
"... Support files are files that are available on the target system only during your product’s installation process...."

If you prefer a way with conditions,  you would need to use "NOT Installed" as a condition for the Custom Actions and for the component with .CER file. Additionally you have to include Transitive attribute (0x0040) for the corresponding component so the condition is re-evaluated on repair (then component with .cer file won't be recreated on repair).

Another option is to use Transitive attribute (0x0040) together with AdminUser property as a component's condition. Then your component (and .cer file) will be installed ONLY when installation/repair is triggered by a user with administrator privileges.
I'm talking about something like this:

rad33k's answer is absolutely correct.
But why not "Keep it simple and stupid"?

With this way you can use the original vendor installer.

Powershell as Example:

<#
.Synopsis
  Install/Uninstall AppGate per Powershell
.DESCRIPTION
  EXE and script(IU_AppGateSDP.ps1) must be located in same directory
.EXAMPLE
  powershell -ExecutionPolicy Bypass -file IU_AppGateSDP.ps1 install
.EXAMPLE
  powershell -ExecutionPolicy Bypass -file IU_AppGateSDP.ps1 uninstall
#>

[CmdletBinding()]
Param
(
    [Parameter()]
    [ValidateSet("Install","Uninstall")]
    $Action = "Install"  
)

switch($Action)
{
    "Install" {
        Start-Process (gci -Path .\ -File -Filter "AppGate*.exe").Name-ArgumentList "/S/M /G" -Wait
    }
    "Uninstall" {
        Start-Process "${env:ProgramFiles(x86)}\AppGateSDP\driver\Uninstaller.exe" -ArgumentList"/S" -Wait
        Start-Process "${env:ProgramFiles(x86)}\AppGateSDP\Uninstaller.exe" -ArgumentList "/S" -Wait
        Remove-Item Cert:\LocalMachine\TrustedPublisher\D6B9C0A13537D0100F693DC2EBFC777EDBADB113-Force
   
}
}

You can start it with powershell -ExecutionPolicy Bypass -file IU_AppGateSDP.ps1 (un-)install

Thank you guys!

I used the Support Files (I didn't know the purpose of it) and it worked fine. But I noticed that the support file is called in repair mode also (not a problem since the certificat deleted itself).

To answer kitco, the client requires a msi, that's why I used repackager.
