when i try to open the patch the installation wizard crashes everytime the game is Starsiege : Tribes

Look in your Event viewer: rt. click My Computer then click Manage then Event Viewer.
Or: Administrative Tools/Event Viewer or Start/Run/ eventvwr
Open the system as well as the application tabs & look for X errors. Click error line for details.
Post back the source & event id & Description especially of errors that seem to coincide with this issue.
Also check the Information lines that might coincide with this issue.

Also view your Error Log via:
[1] Start Menu
[2] Help and Support
[3] Pick a Task
[4] Tools
[5] Advanced System Information
[6] View the Error Log

i looked at each one and there isnt an error or information line that says anything about it

when i double click the update a little blue box comes up that says installing Wise Installation Wizard then the box dissapears and nothing...

Is this the game?

And if so do either of these links help:

http://www.planettribes.com/tribes/upgrade.shtml

http://www.planettribes.com/tribes/faq.shtml

no thats the original game Starsiege , theres also the sequel Starsiege : Tribes and no both of those links are either old / dont help

and ive also tried to install other updates for the game but i think that the installer is broken or something

See if your game is listed in this utility:

Description of the Windows Installer CleanUp Utility

If so remove it and then try to install again.
