The aygshell.dll file can be placed in the \Windows folder, or in the folder where the application itself resides. Several versions of aygshell.dll will work however, the 16.5 kByte version is recommended for ARM devices, while for MIPS devices the 7.5 kByte version is recommended. In order for the interface application to run on the H/PC, the file aygshell.dll, which is not natively present on H/PC 2000 devices, is necessary.You should not get an error message indicating that the program may not be compatible with the device however, if you do, tap on "Yes" to indicate that you wish to continue installation.
Instead, copy the CAB file corresponding to your H/PC 2000 device's processor type, and double-tap on the CAB file on the H/PC to install it. It will not recognize the connected device as a Pocket PC and will close. Do not run the desktop installer to install the program on the H/PC.Note: There is also a third CAB file named "pocketRADIO_ARM_H5450.CAB" this is a special CAB installer for the corresponding model of the iPAQ Pocket PC, and should not be used on any H/PC.)
The ZIP file contains the setup.exe installer file (for installing the application to the mobile device from the PC) as well as CAB files for ARM and MIPS devices.
