The TEncoding.ASCII property uses codepage 20127, which is not installed on XP Embedded by default. You have to install it manually. The TEncoding class does not exist in D2006.

Are you using Indy 10, by chance? It uses TEncoding.ASCII by default for its string encodings. This exact error has been known to occur when using Indy on XP Embedded.

When does it crash? On startup, or later?

That error is only found in one place, in the RTL at least. In SysUtils, constructor TMBCSEncoding.Create(CodePage, MBToWCharFlags, WCharToMBFlags: Integer);, which gets called by TEncoding to set up string encodings.

It takes the CodePage parameter and calls GetCPInfo on it, and if it fails it raises this exception. From the MSDN documentation and the exception message, what's probably going on is that your app is trying to use strings from a multibyte character set that's not supported by XP Embedded. Are you doing anything unusual with strings or text work in foreign languages that use a different alphabet?
