Hi i have files created with old pvx software date create is 2004 but i can not access with pvx server some like pvx basic or some something like that
Have you tried to use PxPlus to access it and are getting and error or are you asking what to use?
Any version of PxPlus should be able to open and read the old PVX data file. You could also use the PxPlus SQL ODBC driver if you want to be able to access the data using software that supports ODBC like Excel.
