Did have a look here?
But running it from a script and first uninstall the older version:
msiexec /x {GUID CODE} /qb!

GUID is the product code of the older MSI.

Cleanest way I can think of is to apply an MST to the newer version, and add older version to upgrades (if its not already there by vendor).

That way, if found it will remove older version and replace it with newer version, if not found it skips that step and keeps going.

If you decide to use the method mentioned above by dddenker, than simply change the /qb! to /qn This way, if it does NOT find the previous version it will not prompt the user stating "No Such Application Exist".

Look at the following string :

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{GUID} or name of the application

Key to look for
-> UninstallString

if it is msi then you can use the above mentioned or if it states something like c:\PF\...uninstall.exe then use it .

if it is exe then you can use /s or some silent switch to uninstall previous version.

I used the method proposed by dedenker (msiexec /x .....). the problem is that the desinstallation of old version was done fine but the new version is not instaled because the remove of old version requires a restart of system so it can do any thing before restarting. So i'm obliged to intervene to restart and to launch the installation after that.
