I cannot get to load in IE7 running under Vista. I have tried the fix suggested in " site unavailable in Vista IE7, works fine in Safari and Firefox", but when I run regsvr32.exe as an administrator, I get the following error message: To register a module, you must provide a binary name." I what binary name to give it or how it should be entered. I would appreciate any suggestions. Thanks.

maggieg103--  The short answer is "Regsvr32.exe was invoked without specifying any modules in the command line"
More info is here
And the official Microsoft comment is here

Thank you for your reply. Unfortunately I don't know what module to specify in the command line. I don't believe the solution I am referencing, site unavailable in Vista IE7, works fine in Safari and Firefox, specifies:

1. Clear your DNS cache.  Go to Start > Run and type CMD
and hit OK.
At the command prompt, type ipconfig /flushDNS
and hit OK.

If using Vista and you get an error, run regsvr32.exe from an elevated command prompt. To get an elevated command prompt, right-click on the "Command Prompt" shortcut and select "Run as Administrator".

Do you know what module I need to enter?
Thank you again,

I suggest you follow the other advice in the answer and forget about using regsvr32.exe...  Incidentally, I am running Vista and I have no difficulty in going to

maggieg103--OK.  Now I understand a little better what you are talking about.  I originally did not know what " site unavailable in Vista IE7, works fine in Safari and Firefox" referred to.
Are you saying you ran ipconfig /flushDNS as suggested and get an error message ?  I do not use Vista, so am a little crippled in giving you exact advice, but I suspect that error message would say something about a need to register a specific .dll file.  Did it?  With the name of that .dll file (taking ulrmon.dll as an example) you would enter the following in a command prompt (without the quotes but with the space after 2) "regsvr32 urlmon.dll" and press Enter.  You should get a message saying that succeeded.
If the error message did not specify a .dll file then look at this reference;EN-US;q281679&
and run the regsvr32 command on each of the .dll files mentioned under Resolution.
Just to ease your mind a little, the earlier E-E thread seems to have left a few things out, so I understand your confusion.
If the above has not helped, let's go back to the beginning.  What happens when you try to enter the site?  An error message?  (If so, what does it say? Page cannot be displayed?)  A blank window?  Is this the only website you cannot access?  Is this something new?
With the answers I will try to help.
Have you tried all the other suggestions made in the earlier E-E thread?

I have followed all of the advise and, unfortunately, still won't load. It's very strange, but not worth more time to troubleshoot. Nevertheless, thank you both very much for your efforts.

Hi I am the poster of the question you reference (" site unavailable in Vista IE7, works fine in Safari and Firefox") and I am sorry I dropped the ball on following up to say that the basic suggestions made by war1 were unsuccessful.  I am still working on this and may post another question and monitor it very carefully now, if that is permitted.  If I find the solution I will be glad to pass it on.

I have found others online who experience this issue, but many Vista users do not have this issue apparently.  It HAS to be something related to my Vista install and IE7, since it works fine in Firefox, Safari, and all browsers I have in XP SP2 as well.

OK I have a solution which I tested and which worked correctly, and I am posting it here so people might use the solution themselves.

I found it at this site:

The short of it is, it appears to be an issue with having either a Tablet PC or a tablet input device (like a wacom) added to your computer, when running not only Vista but even XP and Internet Explorer.  I am running Vista Ultimate 32-bit with SP1, IE 7, and I have an old Wacom tablet hooked up I like to use with Photoshop CS2.

As a quick workaround, people report being able to access nbc through instead, which also works for me.  If you want to access other pages at that site, such as video content, you have to manually add the i back in the URL so it uses that instead of the default again.

For example, I go to and then moving my mouse over the Watch Video choice on the top menu item and selecting 30 Rock from the menu, it changes the URL to which again fails.  If I then change the URL in the address bar to I successfully get to the page.  I can then select a video clip to watch and it works!

Someone at the solution site posted above did some sleuthing and discovered it appears to be related to the User-Agent header for Tablet PC versions of the OS, and it causes redirection to the mobile site, but the mobile site DOES handle the header and sends the browser back to the full site, and this happens over and over until it fails.  I have not verified this myself but it is believable.  Another commenter says they have trouble getting to content as well, but I have been unable to reproduce that problem.

Then someone suggested closing the browsers and deleting the "Tablet PC 2.0" key from HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent\Post Platform and clearing the IE cache.  This worked for me after I cleared both the Files and the Cookies caches.

There are reports from some users of this not working for them, and from others of the key coming back after a reboot.  For me it works fine after every reboot.  But if it doesn't work for you, someone in the comments suggested writing the key removal into a .reg file so its easy to re-run after a reboot.

I hope this helps.  As you can see it was a complex issue unrelated to the solution above.  I am sorry again I dropped the ball on the follow-up of my original problem, but thanks everyone for your help.

Thank you,
