Hi Axel,
Could it be that you are seeing the following error message:
A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available
in order to run Envi_idl. No Java virtual machine was found after searching the following
locations: {VM_SERVER_DIR} in your current PATH
If that's the case, try the following steps:
The following steps may fix the problem (Administrative privileges are required):
1.) Using Windows Explorer, browse to the following directory of your IDL installation (depending upon the bit-version of ENVI/IDL you have installed or are using):
(64-bit ENVI 5.0/IDL 8.2 - default location)
C:\Program Files\Exelis\IDL82\bin\bin.x86_64\
(32-bit ENVI 5.0/IDL 8.2 - default location)
C:\Program Files\Exelis\IDL82\bin\bin.x86\
From this location, create a backup copy of the file
idlde.ini
--for example, calling the backup file "idlde.ini.orig".
2.) Launch a plain text editor with administrative privileges ("Run as Administrator" on recent versions of Windows) to edit the "idlde.ini" file mentioned in step #1.
3.) Make the following change to the "idlde.ini" file:
a.) On the line 2 of the file, there should be a line with the string:
{VM_SERVER_DIR}
b.) Replace this line with the path to the:
[drive]:[install-dir-path]\IDL82\bin\bin.[platform]\jre\bin
subdirectory of your ENVI/IDL installation. For example, for 64-bit ENVI 5.0/IDL 8.2 in the default directory:
C:\Program Files\Exelis\IDL82\bin\bin.x86_64\jre\bin
For 32-bit ENVI 5.0 /IDL 8.2:
C:\Program Files\Exelis\IDL82\bin\bin.x86\jre\bin
After the change first four lines in your "idlde.ini" file would might look like this (for example, 64-bit ENVI or IDL):
-vm
C:\Program Files\Exelis\IDL82\bin\bin.x86_64\jre\bin
-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
c.) Save the change to "idlde.ini".
After making this change, ENVI+IDL and IDL should launch without the error.
I hope that helps.
Cheers,
Fernando
