MiKTeX, GS, GSViewer, ImageMagick, GraphicsMagick and LyX

Thank you for imageMagick portable!

It sounds like a relative/absolute path problem in LyX. I had the same with Texmaker. I think we both need some help with working around it.

Ist das schon das ganz neue Lyx 1.5.3 - so wie das ganz neue MiKTeX 2.7?

The launchers are writen in AutoIt. If someone would help me to migrate them to NSIS, I would like it.
Why?

explain me what is GSViewerPortable and GhostscriptPortable for and how to use it?

I'm trying but no idea...

First of all, thank you for the effort you have taken to create a portable latex environment. Never the less, without documentation our effort is wasted. Here is what I figured from the undocumented code of the miktex application.

All entries from the tray menu can also be activated by calling MiKTeXPortable.exe with a parameter.

lock: activates the portable miktex environment
unlock: deactivates the portable miktex environment
package: opens the package manager - does not work with an already activated env.
options: opens the package manager - does not work with an already activated env.
update: ? updates the application ? - does not work with an already activated env.
solvecrash: ?don't know? - should restore the original registry settings
exit: removes the tray icon without deactivating the portable miktex environment

attention: I somehow managed to mess up my local non portable miktex installation by trying out this portable solution. Most likely I did this by clicking the Solve Crash button. So be aware. You can watch some effects of lock/unlock by observing
HKEY_CURRENT_USER\Software\MiKTeX.org\MiKTeX

Suggestions to the author:

• activate the environment at the start of the application
• deactivate the environment at the exit of the application
• remove lock and unlock options
• allow package, options and update only if activated
• revise solvecrash
• remove the blink effect of the tray icon

I don't know autoit and can't perform these changes on my own.

After the MiKTeXPortable-2.6.paf.exe (or MiKTeXPortable-2.7.paf.exe) is extracted, I run the program, and choose lock from the icon - the very first time, an initialization starts, which for me fails with

Fontconfig error: Cannot load default config file

in initexmf.exe (the last about "default config file" I'm not sure 100% since the command prompt window holds for only a couple of seconds, and will not let me copy text from it) ...

[I found that \MiKTeXPortable\Other\source\MikTeXPortable.au3 contains the commands:

RunWait($path & "\initexmf.exe --dump --mklinks", $path)
RunWait($path & "\initexmf.exe --mkmaps", $path)
RunWait($path & "\initexmf.exe --update-fndb", $path)

Then if I run initexmf --mkmaps -n I get mkfntmap, and when I finally run mkfntmap, I get:
mkfntmap: The config file could not be found.

I found that mkfntmap reads a "updmap.cfg" file; however, that one is present in \MiKTeXPortable\App\MiKTeX\2.7\miktex\config ?? <-- ok, for this, one needs to run \bin\tex_prtbl\MiKTeXPortable\MiKTeXPortable.exe lock to start the environment before running mkfntmap

and here I read that Well, that message doesn't say that it can't find the fonts, it says that it can't find the fonts.conf file. ]

The same goes for both Miktex 2.6 or 2.7... Of course, if after this I run LyX, it doesn't start...
Any suggestions?

[Edit] Ok, I think I got this solved.. Biggest problem is to get some debug messages back TO do that, run everything from command line - run the environemnt first - and call lyxc instead of lyx (lyxc is apparently config, and it was left hanging as a process each time I unsccesfully tried to run lyx):

cd \LyXPortable
\LyXPortable> LyXPortable.exe lock
\LyXPortable> App\LyX\15\bin\lyxc.exe

this finally said that it couldn't find Python... So, while still in environment (that is, within LyXPortable.exe lock) command prompt, I tried

\LyXPortable> set PATH=%PATH%;C:\Python24

as I had Python from before, ran lyxc again, started getting "+checking for package", lyxc passed, and lyx started
