You can try using the offline installer available under 'Still having problems' section on Installation problems | Flash Player | Windows 7 and earlier page.
Also, I'd like to investigate why you are getting the 'Application Initialization Error' using the online installer. Can you please upload the Adobe_ADM.log and Adobe_GDE.log files, saved at C:\Documents and Settings\<YourUserID>\Local Settings\Temp\ to cloud.acrobat.com/send using the instructions at How to share a document?
Thank you for your prompt response, I have created the link for the files that you have requested, please would you confirm the email address that I should send the link to please.
As mentioned in the last step in the document, paste the copied link into your reply post.
Sorry must have missed that bit!!
Here is the link........
And, thank you, yes going through the other route does appear to have installed Flash.
