RDC pre-release expired

getting error of the pre-release version of remote desktop connection has expired,when trying to use rdc.

I have replaced mstsc.exe and mstscax.dll , in both windows/system32 and in the windows cache file...BUT after a few seconds it reverts back to old copies...what am i doing wrong?

Are you talking about a Remote Desktop client or server?
Please post the OS (XP?), the architecture (32bit?), the edition (Professional?) and report if it is fully patched with SPs and HFs.
Thank you.

BTW: system files are protected by the OS against overwrite. This is why (likely) it reverts to the old copies.

There are several ways you can fix this:
You can copy the files from a Windows XP SP2 computer and then Windows Remote Desktop should work again.
a. mstscax.dll
b. mstsc.exe
Copy the files in safe mode otherwise windows will just recreate the files even if you replace them or delete them

Or you can download an update from the Microsoft download site and it will get your Remote Desktop working again.
Update for Windows XP (KB969084) - The Remote Desktop Connection 7.0 client update enables you to use the new Remote Desktop Services features.
Please read the Known issues in Windows XP from the KB article above.

pre-release version of remote desktop connection

Which operating system are we talking about here? Server 2012R2 ? This is the only pre-release software that is an RDP server that has licensing at the present time.  Pre-Release software is not designed for production use. The RTM bits are available on MSDN/Technet.. You can use S2K12 not R2 CALS. (AFAIK)
