Hi,it says in the info not tested for vista but being a public domain program thought worth a try.Tried the combatability change but no luck,same as running as administrator.I did find one version written in java,that one worked fine but was only a partial version.The tcd files seem to be hard to find any info on,found a couple of supposed readers but sure didn`t recognize the source so was afraid to try,the one I found some other references too and tried didn`t work.Thanks for the input.
