Java SE (Java Platform, Standard Edition)

I cannot install jre6 update 10 or 11. Both attempts (from full download) result in:

If I try the online install (update 11), the download runs to completion, then the install program terminates with no messages at all.

I CAN re-install 1.6.0_07 from jxpiinstall.exe, downloaded Oct 24.

I have disabled virus checking, and whatever else I could think of!

System is Windows Vista 32 bit with SP1.

Has anyone else experienced this problem, or have any suggestions?

Thanks...... Graham
