Unity 64 bit web player instalation fails

Hi I have installed the 32 bit web player for battlestar galatica online but wanted to use the 64 bit player as it seems more stable. However I cannot get it to install.

Have cleared my unity cashe and cleaned up the registry with ccleaner and even deleted every unity folder I can find but still no luck.

Error msg: Installation Aborted Setup was not completed successfully

Thanks for any help

UPDATE - I have just put on my system a clean build of windows 7 and Unity 64 bit still fails to install with the same error as above.
