I have a problem here that i m not able to install the cab file on my emulator. I have followed he steps to make the cab file given on :
<http://www.mobilepractices.com/2008/10/setupdll-sample-and-walkthrough-terms.html>

then i m copying the cab file on the path "Windows-->Start Menu-->Accessories"

Now when i try to install it from emulator I get this error message..........."Installation was unsuccessful.The program or setting can not be installed because it does not have sufficient system permissions."

one thing to be noted more that even i m not able to configure the emulator-->> i m trying to go to peripherals then when i try to change "Serial Port 0" to "COM3" i get an error message "Unable to open serial port COM3.LastError=The system can find the file specified. "and "Error: Problem updating configuration.Not all settings have been updated."

So is the problem related to my emulator settings or i have some problems with my cab.

if any body knows the solution please tell it ASAP.

regards

Madhup
