Hi, I installed Virtual PC 2007 (free download from MicroSoft) and installed Vista Ultimate under the virtual machine. (for the time being I have no plans to install Vista on any of my machines)
When running as administrator, DX4WIN runs fine. I do not get any error messages etc and the port driver is loaded. As a regular user, the port driver cannot be loaded. Versions prior to 7.03 would exit when this happens; I modified the code for version 7.03 to ignore this error, with the result that access to the LPT port(s) is disabled. I guess that the experiment worked, because my laptop is 32 bits. If you run the 64 bits version of Vista, loading the device driver will not work; even for the administrator. Will keep you posted, --Paul ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Paul van der Eijk (KK4HD) [EMAIL PROTECTED] http://www.dx4win.com
