windows with only h: without c:

[Yod4z]

i have some clients with only windows installed on h: and no drive c: and when you launch chunkvnc it can't decompress on c:. Is it possible to edit the script to decompress on c: or another available partition?

Looks like a Problem with the Aut2exe.exe in the SRC\Aut2exe-Directory. (That Exe compiles the scripts into an Executable with all needed files. If you run the compiled Exe-File, the include files get extracted and the scripts starts running.)
You could try to download an actual version of autoit 3 and replace the Aut2exe with an more actual version and check if that helps. I don't have a PC with an systemdrive other than C: here, and it isn't clever to change the driveletter after installing windows, so i can't help you with testing it out

is autoit that determine the WorkingPath?

There is the variable @AppDataDir in the script, that give the actual AppData-Path from the system and the script depends on that variable. Looks like a Problem with that path in your case, so yes, i think it's an autoitproblem

AFAIK I didn't hard code any paths into the software so indeed you guys are right that it's an autoit problem.
Try updating all the files in the SRC\Aut2Exe folder from the newest download here: http://www.autoitscript.com/site/autoit/downloads/
Remember to recompile everything.

Let us know if this works.
