Divx Cache Probems can't locate / change it.

I Installed the Divx web player in hopes that i could play some videos online but so far even changing the install location hasn't helped. It keeps saying no space on C: for cache but It is clearly installed to D:. C: is a 6gb HDD with the OS and a few other critical programs so how can I change the Temporary folder for the Divx player or at least know where it is then i may be able to do something about it. D: is a 500gb hdd with a few gb free.

I am Running Windows XP up to date with Firefox up to date.

 

For those few People with little hdd space on C: drive.

Open up the Control Panel and open the one called System. Then Click on the advanced tab and at Bottom theirs a button that says "Environmental Variables"
Then Edit the variable TEMP and TMP and change the location which was "%USERPROFILE%\Local Settings\Temp" to what ever you prefer in my case "D:\Program Files\Temp". Then Click Ok and Ok and you may have to restart.
