Can't install Remote Desktop Activex Control
Using Windows XP Pro and trying to access computer remotely but Windows tells me it need to install "Terminal Services ActiveX Client" but it won't let me install it. Tried this solution which worked on two other computers, but not this one:

Method 2
1. Click Start, Run. Type Regedit.exe and press ENTER

2. Navigate to the following branch:

3. Double-click Settings to expand the branch.

4. Right-click {7584c670-2274-4efb-b00b-d6aaba6d3850} and choose Delete
(Repeat step 4 to delete any other problem keys)

5. Click Yes when asked for confirmation.
Close all instances of Internet Explorer and re-run Remote Desktop Web Connection.
On the problem computer, there is no "Settings" Key -- when I navigate to "Ext" the only choice is "Stats" so the above solution isn't any good.

This is also mentioned as a solution in that same link:

Registry Solution

Enable the below class ID:

Windows Registry Editor Version 5.00

[-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Ext\Settings\{7 584c670-2274-4efb-b00b-d6aaba6d3850}]

Disable the below class ID:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Ext\Settings\{7 584c670-2274-4efb-b00b-d6aaba6d3850}]

Example of all the registry keys that you may need to delete to make it all work:

Windows Registry Editor Version 5.00

[-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Ext\Settings\{7 584c670-2274-4efb-b00b-d6aaba6d3850}]
[-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Ext\Settings\{4 eb89ff4-7f78-4a0f-8b8d-2bf02e94e4b2}]
[-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Ext\Settings\{7 390f3d8-0439-4c05-91e3-cf5cb290c3d0}]

Note: You may also need to completely remove the below registry keys

More Information:

If the Windows XP/SP3 service pack is download and then extracted, you can find a VBS script that can be used to rectify the problem.

The file name is: tscuinst.vbs

Command: cmd.exe /C "cscript %systemroot%\Installer\TSClientMsiTrans\tscuinst.vbs"


The IE Support Team
Not sure what that second solution is telling me to do. I'm thinking maybe create that key and then delete it after running IE, but I don't know what suppossed to be in the key in the first place.

Any ideas?

BTW--when I go to Tools, Manage Add-Ons in IE, everything is enabled.

I am having trouble following what you wrote. Can you explain your setup more plainly? Which OS is the server using? And the client?
You are trying to setup remote access, right? What software are you using? How did you set it up? What exact steps did you follow?

Have you enabled ActiveX on your browser? Have you added your remote access site to the Trusted Sites?

And the first question to ask everyone who is having apparent problems with their operating system(s) but did not answer this: Have you applied all updates, including Microsoft and all related to installed hardware?
