There are reports on the internet that Internet Explorer 10 64bit can have problems opening PDF files.
A "fix" is to uninstall it and use Internet Explorer 9. If you want to try this then follow this guide.
Uninstalling Internet Explorer 10 will automatically restore IE9 once you complete this process.
First of all, click on the “Start” button and type “Programs and Features” in the search box. Click on the “View installed updates” in the left pane of the menu.
Go over to the “Uninstall an update” screen and scroll down to the “Microsoft Windows” section. Simply select Internet Explorer 10 and click “Uninstall.”
It usually takes a while until the process comes to an end, so you’re strongly recommended to avoid stopping or cancelling
it. A reboot is necessary to complete the removal and restore IE9.
After that try your email and report back.
With regards to going into the Adobe preferences you have to untick the box that says display PDF in browser then click OK
Sorry to be giving you all these things to try but before uninstalling IE10 try turning of the Enhanced Protect Mode to see if that helps.
To turn Enhanced Protected Mode on or off
Open Internet Explorer, click the Tools button, then click Internet options.
On the Advanced tab, under Settings
To turn Enhanced Protected Mode off, untick the Enable Enhanced Protected Mode checkbox.
Restart your computer after this.
I now have IE9 but it has made no difference. Should I be thinking of downgrading Adobe Reader from version 11 to one that was compatible with IE9 as well?
Thanks for all your help to date.
I am running out of suggestions. Yes you could try uninstalling the Adobe reader on your computer and downgrade to Adobe reader 9.5 via this link.
Did you try pottypersons suggestion of turning off your antivirus real time scanning temporarily to see if that was causing the problem?
You could also try reverting back to BTYahoo classic mail. This might only be a short term fix because BTYahoo is upgrading its mail whether you want to or not.
This is a guide supplied by Andy N if you want to try it.
1). Close any Yahoo! windows with mail or anything else.
2). If you are unable to see a Tools menu option, right click the IE window top bar and tick "Menu Bar"
3). Click on Tools/Internet Options - then click on the Security tab
4). Press the Custom level... button
5). Scroll down to Scripting (towards the bottom of the list of settings), and click on the Disable option in the Active scripting feature.
6). Click on Yes and OK as necessary to exit from the Tools window.
7). Login to webmail, I suggest using http://mail.yahoo.com, using your whole @btinternet.com email address as the Yahoo! ID.
I have tried everything including going back to Classic mail (which incidentally displayed a message to transfer back to the new version almost immediately) and also trying pottypersons suggestion but all to no avail.
The error is obviously down to me at some stage and due to my lack of knowledge and understanding on these matters, It looks like i will have to take my laptop to a specialist to unravel this mystery.
Thank you all, but mostly to you gg30340 for your time and effort in trying to sort this perplexing issue for me.
The last thing to try and I'm pretty sure it won't work is to do a factory reset on your homehub by pressing a pin into the recess on the rear.
I'm pretty sure the problem is not down to you causing the error. I'm sorry I can't help you any more. I would be interested to hear if you do get the problem sorted. Take a note of everything you have done so that whoever tries to sort it for you will at least know what has been tried.
