Quickly Clear Cache with Login AM 2012 Cache Cleaner

Quickly Clear Cache with Login AM 2012 Cache Cleaner

You are probably aware that Login AM will create an entry in the tracking.cache after the application installation is finished. Even when the installation failes this entry is created. To install the application again by Login AM you will have to remove the application entry from the tracking.cache and reboot to start the install phase again. By deleting the entry, Login AM will think the application is new because it is not in the tracking.cache.

A customer of ours asked if it is possible to create a tool that removes an entry from the tracking.cache based on only the servername. This triggered me to create the following tool.

For the GUI I used a program PrimalForms. With PrimalForms it is very easy to create buttons, input fields, tabs etc. When the GUI is created in PrimalForms, use the Export Powershell button to create a powershell script. My GUI looks like this:

Because the GUI is just a GUI we need to create some actions for the buttons.

Analyze Button

In the code of the Analyze Button I set two variables. The first variable $path2tracking is the path to the cache file. Always use the admin share path without the servername (i.e. C$\S4\workfolder). The second variable $servername will use the servername from the input field.

 $Button_Analyze_On-Click= {
 
#variables
$path2tracking = "c$\s4\workfolder" #Fill in path to tracking.cache via adminshare
$servername = $Input_ServerName.Text #Get servername from inputfield
 #Get TrackingCache Result
$result = Get-Content \\$servername\$path2tracking\tracking.cache
    Foreach ($item in $result) {
        $Dropdown_TrackingEntry.items.Add($item)
    }
}

The result is shown in a dropdown menu.

Then we have to delete the entry from the cache file. This is done by selecting an entry via de dropdown menu and to click the delete entry button.

 $Button_Delete_On-Click= 
{
#Select entry from tracking.cache, delete and save tracking.cache
 $SelectedItem = $Dropdown_trackingEntry.SelectedItem #Select dropdown item
 $SelectedItem_esc = $SelectedItem -replace "\\","\\" #Changing format
 $result -notmatch "$SelectedItem_esc" | out-file \\$servername\$path2tracking\tracking.cache #Save changed cache file
 #Clear Dropdown menu
 $Dropdown_trackingEntry.items.Clear()
 $Dropdown_trackingEntry.Text = ""
}

The Login AM 2012 Cache Cleaner is available for download at the following location.

Can this tool be used for other purposes? Yes it can, Login AM also uses a printerdrivers.cache file with the same format as the tracking.cache. Just change the path to the cache file.

I hope this tool can make your life a little bit easier when it comes to reinstalling applications with Login AM. Please let me know if this helped.
