Thank you for your help.
I tried removing the folders as suggested and then running the installation from the web page and got the same result.
I have pasted the error details below (the strange thing is that it appears to suggest that the operating system is 32bit when I'm pretty sure it is 64bit).
Thank you in advance for your help -
