Remote Desktop Connection 6.1 (RDP 6.1) on Windows XP WITHOUT SP3. RDP 6.1 on Win XP with SP2

Posted Saturday, 07 June 2008 by Misha Hanin

Recently, on one Windows 2008 I've installed a Terminal Server Role and did a TS Web Apps. Really nice feature, you can get access to application through web interface, exactly how it's done on Citrix, but by using Windows 2008 you not requested to buy a Citrix ;). Yes, TS Web Apps from Windows 2008 is a nice, but to get access to this application, on a client side should be installed RDP 6.1 client. This particular version of RDP cames with SP3 for Windows XP or with SP1 for Windows Vista. I have no idea why Microsoft doesn't provide RDP 6.1 as separate package.
In my case I couldn't install XP SP3 or Vista SP1 on every machine in Network, so I've found a workaround. The first step is to install a RDP 6.0. After that we need to get few files from XP SP3 or Vista SP1. Create anywhere on your disk directory, let's say RDP6_1 and put there the following files:

lhmstsc.mui
lhmstscx.mui
mstsc.chm
mstsc.exe
mstsc.exe.mui
mstscax.dll

Inside RDP6_1 create directory en-us and put there the following files:

aaclient.dll.mui
mstsc.exe.mui
mstscax.dll.mui

NOTE: Remember to take all mentioned files from Windows XP SP3 or from Windows Vista SP1.

Now inside RDP6_1 create a batch update.bat. Here is a content of update.bat :

del c:\windows\$ntservicepackuninstall$\mstsc.exe
del c:\windows\$ntuninstallkb925876$\mstsc.exe
del c:\windows\servicepackfiles\i386\mstsc.exe
del c:\windows\system32\mstsc.exe
del c:\windows\system32\dllcache\mstsc.exe
del c:\windows\lastgood\system32\mstsc.exe

del c:\windows\$ntservicepackuninstall$\mstscax.dll
del c:\windows\$ntuninstallkb925876$\mstscax.dll
del c:\windows\servicepackfiles\i386\mstscax.dll
del c:\windows\system32\mstscax.dll
del c:\windows\system32\dllcache\mstscax.dll
del c:\windows\lastgood\system32\mstscax.dll

copy mstsc.exe c:\windows\$ntservicepackuninstall$\mstsc.exe
copy mstsc.exe c:\windows\$ntuninstallkb925876$\mstsc.exe
copy mstsc.exe c:\windows\servicepackfiles\i386\mstsc.exe
copy mstsc.exe c:\windows\system32\mstsc.exe
copy mstsc.exe c:\windows\system32\dllcache\mstsc.exe
copy mstsc.exe c:\windows\lastgood\system32\mstsc.exe

copy mstscax.dll c:\windows\$ntservicepackuninstall$\mstscax.dll
copy mstscax.dll c:\windows\$ntuninstallkb925876$\mstscax.dll
copy mstscax.dll c:\windows\servicepackfiles\i386\mstscax.dll
copy mstscax.dll c:\windows\system32\mstscax.dll
copy mstscax.dll c:\windows\system32\dllcache\mstscax.dll
copy mstscax.dll c:\windows\lastgood\system32\mstscax.dll

xcopy *.* c:\windows\system32 /e /y
regsvr32 %systemroot%\system32\mstscax.dll /s

Update.bat should be run after installation of RDP 6.0
Now, you can navigate to your TS Web Access and run RemoteApp Program.
