Originally posted by Pentax-LBA I had the same problem, but fixed it. I am using Windows Vista. If you ar using Vista, you need to run the program as administrator. You can do this in two ways. Right click the shortcut of the application and select Run as Administrator. You would have to do this every time.
The best way is to find the application file PRMAST03.exe in the application directory. The easy way to do this is to right click the program shortcut and select properties. Select the Shortcut tab and then click Open File Locatino. Right click on PRMAST03.exe and select properties. Select the Compatibility tab near the bottom and place a check mark in the box Run this program as administrator. Click OK. Now every time you start the program it should run automatically. Let me know if this does not work.
That worked for me as well.
Many thanks.
