Java SE (Java Platform, Standard Edition)

Hi!

I am trying to install jdk-6u1-nb-5_5-win-ml.exe on my computer but during the installation wizard I get the error;

WARNING:cannot instantiate string resolver method com.installshield.util.LocalizedStringResolver:
com.installshield.database.ISSqlException:Table already exists.....................................a lot of sql statements here.................WARNING:could not delete temporary file
C:\DOCUME~1\pc\LOCALS~1\Temp\ismp003\1783180

WARNING:could not delete temporary file
C:\DOCUME~1\pc\LOCALS~1\Temp\ismp003\4410326


I had installed java platform before but then in order to also install netbeans
(as a complete packet with jdk-6u1-nb-5_5-win-ml.exe)I had uninstalled it and now I can not install anything.Do I have to reformat my computer??

I will be glad if you help me..

Thank you:)
