Hi, Is WPI running thru the network ? I tried with the version 4.3 i get a message error. I tried with the version 5.3 too i get a message 'can't find the glossy them' The path is like .\\<IP>\....\TOTALWPI\WPI.HTA The folder TOTALWPI contains all files and fodler needed. Actually i burn the same source on a DVD, it's running as well . Thanks per advance WPI experts.
