"Not running in high contrast, so we will paint the background with our trademarked image" configuration wizard hangs

We have update the sharepoint sp2 on our farm, but configuration wizard hangs on the step 8 of 9.
We have tried many solution but no luck.
Then we have uninstalled the sharepoint and follow the following steps :
Install the sharepoint 2007,to run canceled the configuration wizard.
Installed the SP1 of WSS
Installed the SP1 of office server
Installed the SP2 of WSS

It works fine this time.
