The KForCE page seems to suggest that it's for Windows Mobile 5 and 6, even though there are screenshots on the page from a Pocket PC 2000 device. If you're trying the WM 5/6 version, it won't work on the V212 because WM 5 and 6 are based on CE 5.01 and 5.02, respectively, so the device won't recognize them as compatible with CE 5.00. Also, the program likely requires some DLLs native to WM 5/6 - in particular, the version of coredll.dll on the V212 may not be compatible. An older version may work if you can still track it down.
