A new version is out (see first message)
http://sourceforge.net/projects/gimp-pa ... z/download



Lacertile

It seems as you started gimp from gimp.exe,(in the bin folder) you should use instead Gimp-2.8.0-RCI-1.exe visible at soon you open the main folder.

Anyway was a different problem now fixed i suggest to switch to this
http://sourceforge.net/projects/gimp-pa ... z/download

but again you should start (this version of gimp ) clicking on "Gimp-2.8.0-RCI-1.exe" not on gimp.exe
(as in partha portable you should use gimprun.exe )

I tough was solved ,you didn't reply to my previous message:
i asked if you was starting gimp clicking on "gimp.exe" that would have explained yours and lacertile problems

You may confirm that instead you are loading gimp clicking on Gimp-2.8.0-RCI-1.exe ,but the problem remain?

please let me know

bad new
not sure what could be the cause i hope i can fix soon
the same utility that allow portability should also take care to "translate" the path when is moved in a different drive but obviously in your case doesn't work

I unpacked the program to a secondary hard drive and started it by clicking on the link you specified, but it still will not open .jpeg files. It still says it's an unknown file type. It will open .xcf files fine, but won't recognize any file type outside of that.

Sorry something breaks portability
I temporary remove the file till i find a fix

I know better Partha build, with this i try to build on Samj portable build but she use a more complex system (i believe more powerful and flexible , but more mysterious to me,is called Mareguin ) to allow portability...evidently something screw up the mechanism...well i will see if i can fix or i will port back everything to the last 2.7
