7.82.881 under Windows CE 4.xx .net. You don't need to run the installer at all - the download ZIP package includes within it another ZIP file called
Inflated.zip. Open that, and you will find the CAB files. Copy the one labeled
wireless.ARMV4.CAB over to the 900C and run the CAB file on the 900C to install it.
Let us know if that works.
