Threed16.ocx is a shared Microsoft file that is being deleted on some PC's, possibly when other software is uninstalled. The solution is to do a full install (5 Mb), and then upgrade to your version.

You can also download threed16.ocx - it needs to go in C:\Windows\System and then registered with REGSVR.EXE (and not REGSVR32).

Installing Upgrades

When you download a new version of the software your browser should ask you where you want to save the file (e.g. UPG217.EXE). You can save it in any folder, but you might consider creating a folder called, say, C:\1FROMNET.

After it has downloaded, use Explorer and double click on the downloaded file. A normal Windows installation programme will run and prompt you to install the new version in C:\PRWIN. You can then delete UPG217.EXE , or you could keep it in case you need to re-install.
