java\bin files not installed

I have windows 7

After downloading arduino and installing, i had to skip following files, which would not install. why?

awt.dll
fontmanager.dll
java.dll
javaw.exe
net.dll
nino.dll
verify.dll
zip.dll
client\jvm.dll

the installation does not work.

Is this a case of java being updated and not backward compatible to old arduino software
needed for hardware being sold?

If so were can i find old copies of these files to replace the modern ones,
that appeared in the file after installation, but do not apparently work?

anyone out there have an answer?

I would seriously appreciate your help
