Report it to Microsoft. You're using beta software, so you assume the risks associated with such, including that it may not work properly.
Report the problem to Microsoft and hope they have a fix or get around to fixing it before launch.
I have OS Windows Vista, after I downloaded IE8 my 'Adobe Flash Player' disappeared. I tried to downloading from Acrobat.com I got errors that read: "you may need to click on Gold Tool Bar above" but there was no (gold tool bar to click).
after couple tries, High Security Level popped up. I lowered the Security and Privacy at lower default and gave it another try. I still get the same! However, I?ve never had this issue when had IE7?
I am an SQA/Validation analyst!
Thank you in advance,
