GIMP: Crashes when opening EPS

Dear All,
just made a fresh install of the Portable Apps Platform, than installed Ghostscript, after that GIMP.
When trying to open an EPS, GIMP crashes as below.

I tried as recommended in many forums (analog to the non-portable version):

"""""
So this is the solution:

If you have not already, download and install Ghostscript 64-bit
Copy gsdll64.dll from your Ghostscript bin folder (Eg: C:\Program Files\gs\gs9.07\bin\) to the GIMP bin folder (Eg: C:\Program Files\GIMP 2\bin\)
In the GIMP bin folder first a) Rename the file libgs-8.dll to libgs-8.old, and then b) Rename gsdll64.dll to libgs-8.dll
Restart GIMP and opening EPS images should now work
"""""
but failed.

WIN7x64 SP1, latest PA-Plattform,latest Ghostscript, latest GIMP.

Anyone any ideas?

Thanks for your help in advance,
