I have the Samsung Gravity T SGH-T669. I couldn't get New PC Studio version 188.8.131.5264_2 to run at first on my HP laptop with Windows Vista. But now after some debugging I got it working at was able to sync my calendar and phone book. I am connecting with a universal USB cable from T-moble.
Things to try:
1. I noticed there was a NPS connection manager running under my Admin account in Vista. I turned that off temporarily to experiment.
2. I was getting a missing flash.ocx error when I run NPS under my Admin account. So installed new flash player using Microsoft browser IE. That took care of the flash problem. I was trying to install using firefox and that did not work.
3. With the above changes I was able to get it to run on admin account.
4. Now I wanted to get it to run on regular user account. When running NPS, I get "running module failed". I run NPS as Administrator in Windows Vista and it runs fine.
