I have documented these notes here in case they could be useful or of help to someone else.
A few days ago I got a new (refurbished) Toshiba Satellite L855D laptop, which came installed with Win8 +IE9.
I ran it through numerous Windows Updates, and that got it an up-to-date Win8+IE10.
In the process of setting up Firefox and IE10 to suit my needs, I encountered a problem - LastPass installed and worked fine in Firefox (latest ß version), and installed fine in IE10, but it but repeatedly crashed IE10 when I tried to sign on to LastPass.
I spent quite a bit of time looking for a possible solution on the Internet and in LastPass' knowledge base, but found none.
So I posted a problem ticket in LastPass support:
LastPass repeatedly crashes IE10 as soon as I log in to LastPass - using IE10, Win8. Lastpass is thus unusable in IE10.
Microsoft Visual C++ Runtime Library
C:\Program Files\Internet Explorer\iexplore.exe
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
LastPass support updated the ticket with this:
Thank you for contacting LastPass Support and we do apologize for the inconvenience it may have caused you.
Please update your Internet Explorer to the current version here: http://windows.micro...-worldwide-languages
This would have necessitated my upgrading from Win8 to Win8.1, and I wasn't able to do that because of another (apparently common) problem. In any event, I could not see the need to update.
Not happy with this, I posted a comment to the ticket asking LastPass support to confirm whether LastPass supported Win8+IE10.
A deafening silence ensued.
So I did some more fossicking about in Internet forums and eventually came up with several comments that said that:
LastPass does not work in IE10 in Win8 because IE10 starts up in "No Addons" mode (when started from the Start menu). The workaround is to start up IE10 from the cmd box, and then LastPass works correctly in IE10.
So, I tried that out, and LastPass worked just fine in IE10. My feedback to the LastPass ticket:
Case can be closed: I discovered that LastPass does not work in IE10 in Win8 because IE10 starts up in "No Addons" mode. The workaround is to start up IE10 from the cmd box, and then LastPass works a treat in IE10.
Come on - you guys really would/should have known this better than me, so your advice to upgrade to Win8.1 was rubbish.
