You said you had tanx on your computer at one time.
How did you remove it? did you use the unis000 file or another way?
You may have part of the download still installed and its messing things up.
I checked my tanx folder and found files in it like IS-4SMAC.OMP, IS-5V6DK.OMP, IS-T1ARB.OPM
Sometimes you can uninstall a program and depending on how you do it, some of it will be left behind.
I would suggest doing a search for a "Tanx" folder on your computer and see what you find.
You may even find the old download file "TanxInstall" and be able to use that.
