Use RDP Client 6 (from Vista) on Windows XP

UPDATE! The newest client found in the release candidate of Vista does not require MUI files at all. There is some speculation that this may in fact end up as the Windows XP RDP 6 client. Download RDP 6 Client for Windows XP using this link.

I’ve been trying to get the Remote Desktop Connection v6.0 client from Vista to run on Windows XP for months now. Microsoft has announced many times that it’s available tobeta testers through the Connect site, but try as I may I still can’t find it (I’m not alone). So I went ahead and popped the new RDP 6 client from Vista onto Windows XP and tried everything from dependency walking to regsitry hacks to get it going but to no avail. So i kept testing, and set up a Google alert to let me know if anyone had found a method or any information that I could use to get this done.

I got results from the hook today, and what a big fish it was. It seems that I had probably fixed it early on, but hadn’t followed the proper procedure of changing one setting, testing, then moving to the next. I had simply set up all the hacks I thought were needed and plowed ahead. This is what happens when you test with a bottle in hand.

So here is what I found out today: originally from a thread by Caelum over at AtomicPC, this quick hack allows you to install the Microsoft Vista RDP v6 client on a Windows XP computer. Caelum was trying to get widescreen working in RDP on XP, and most of you know that works fine already. But Caelum, you’ve solved another problem in the process!

The 6th iteration of the MSTSC binary has a bunch of outstanding feautures. The biggest one for me is better support for sound and video over terminal services, but also includes ClearType support for those with LCD monitors so fonts look much nicer now.

Let’s get cracking.

1. Download this MSTSC zip(1.3MB)

2. Unpack the ZIP file to a folder

3. Run the “Install.cmd” file

4. Once the installation has completed, press any key to close the window

5. The script does everything but copy the MUI files to SYSTEM32, so we’ll do that now: open your Windows folder, then SYSTEM32, and then en-US. Copy the *.MUI files from your unzipped folder to the en-US folder

6. Run your remote desktop connection application the same way you normally would

Note: If you use Windows XP 64bit Edition you’ll want to grab the 64bit bit files from a 64bit version of Vista.

Now we can connect to Vista and Longhorn Terminal Server using the most up to date client and test the new features offered by Remote Desktop Client 6. I’ve tested this out on both using my VMWare Server virtual machines and the results are very favorable so far – it’s faster than before!
