Problems with license files
If WinGX or Ortep3 complain about a missing license file, it means that
no file with the correct name is found in your home directory. For WinGX the home directory will
almost certainly be c:\Users\"username"\AppData\Roaming\wingx, where "username" is the user ID
name you use to logon to your computer. This is where the license file and ini files are stored.
For Ortep, the relevant directory is c:\Users\"username"\AppData\Roaming\ortep3 and for PWT
it is c:\Users\"username"\AppData\Roaming\pwt
On non-English computers, the folder c:\Users may be called something different but equivalent.
There are TWO (and only TWO)
possible reasons, and at least one of them MUST be the cause of your problem.
Please look at these VERY CAREFULLY - I will not respond to
any emails on this topic, since this page says all I have to say about the
matter.
- Most likely the file is incorrectly named (misspelt) or is in the
wrong place - please check carefully with the information given in the email.
The license files should be
called "Ortep3-license" or "WinGX-license" (without the quotes marks " of course)
as appropriate (the programs
now also accept these names with a ".txt" extension). They must be in the
home directory as explained above. Make sure that
Windows Explorer is showing you the FULL file name (and not hiding extensions) !
- Secondly, if the license file is present but the program cannot read ANY
of the entries, it may also report that a license file cannot be found.
This can happen very occasionally if your emailer really screws up the text file.
Please check below about invalid licenses.
If WinGX or Ortep3 complain about an invalid license file, then probably
your emailer has screwed up the ASCII file sent you.
To see if this has happened, open up your license file in
any text editor (such as NotePad, but NOT a Word Processing program).
The last part should look very similar to this (any text
before the first ######## marker is irrelevant, and of course the license
number will be different).

Program license for : WinGX
User name : Louis J. Farrugia

There should be six and only six text lines between the delineator markers #####,
each beginning with a designator name. Each piece of information
starts on a new line. If it does not, then edit the file to look as
above (if e.g. lines have become wrapped - the User Affiliation string
can be a very long line and some emailers wrap this line over several lines). The most important information
is the license number and email address.
These must never be changed. Please edit your file so that the layout is EXACTLY as above in
the example.
