Fireamp removal via command line

[IT Department]

I'm trying to automate the removal of Fireamp via the command line and its not working.  If I run the command and enter the password it works.  If I run it silently it doesn't.  Any Ideas?  Im using the command line example below

for this example Ive substituted our password with pa$$word

C:\Program Files\Sourcefire\fireAMP\4.1.0\uninstall.exe /S /uninstallpassword pa$$word

The fireamp icon flashes like its doing something but fails to remove.

I apologies for delayed response. As this is very old thread, just want to confirm, are you still facing this issue.
