Adobe reader in internet explorer 8

Hello all
I am using windows 7 RC on my system with internet explorer 8. I am facing a problem in viewing a PDF file in internet explorer 8. I am not even able to open the files. When I download a PDF file and try to open it in adobe reader, it opens successfully and same is the case when I try to view it in Firefox but when I try to open it in windows explorer 8, I am met with an error. The screenshot of the error is as follows:

Now what kind of an error is this which is completely blank. It is not directing me in any direction. Can someone please tell me what should I do to remove this error?
Waiting for your helpful suggestions
Thanking you loads
Harry
