Download the file with the "Save to disk" option in your WWW browser into a temporary folder, and unzip it. It contains two files, a README.TXT file and PLT71SETUP.EXE, a self-installing executable. To install WINPLT v7.1 on your system double-click on the file PLT71SETUP.EXE in Windows Explorer and follow the prompts (the installation is completely reversible with UNINSTALL).

The installation can be run in English, German, Italian, French or Spanish (PLT itself uses English only).

Downloading and installing WINPLT on Windows-7

Microsoft has made changes in Windows 7 that no longer allow the current WINPLT installation programs to function, Until this problem is resolved, you can install WINPLT manually as follows (this will, of course, also work for earlier versions of Windows if you prefer a hands-on installation): In another mean-spirited move Microsoft has decided that it will no longer support the WinHelp files used by WINPLT. You can install the needed support files by following the directions in this link

PLT is fully functional without a password, except that a nag screen might apear, and "Unregistered" text might be added to exported drawings.

Upgrading WINPLT

Upgrades and bug fixes will be periodically posted, and can be dowloaded here:

Unzip the file and copy the contents into the WINPLT folder (it might be a good idea to back up your old PLT installation in case some unexpected problem develops with the new version). There will typically be only the executable (PLT71.EXE) and help files (PLT71.HLP). Occasionally there may be new support files. Currently the upgrade ZIP contains the CIMAGE.DLL and FREEIMAGE.DLL files, which should be placed in the WINPLT folder. This is not a complete install and can only be used to upgrade an existing installed copy of WINPLT Version 7.1.
