    Hi,

    I am trying to launch IBM ILOG Optimization Studio 12.2 (32 bit) IDE on my Windows XP (with service pack 3) running 32 bit Intel Core2 Duo processor. The installation was successful. But when I try to launch (following "All Programs" -> "IBM ILOG" -> "CPLEX Optimization Studio Academic Research 12.2" -> CPLEX Studio IDE") I get the following errors (the snapshot attached).
    org.eclipse.core.runtime.internal.adaptor.EclipseLazyStarter$TerminatingClassNotFoundException: An error occurred while automatically activating bundle ilog.odms.ide.opllang (19).

    The I tried to execute the oplrun.exe from command prompt. But then I get the following error message.
    "The system cannot execute the specified program."

    I have checked the PATH variable and see that all required libraries are included in the PATH, including the <installation_dir>\opl\bin\x86_win32\opl122.dll.

    Can anyone please help me to resolve the issue?

    Thanks in advance!

    The fact that both oplrun and the OPL IDE have problems is strange, because they are in fact completely independant.
    Oplrun necessary dlls are taken from the bin\x86_win32 directory, but the IDE takes its native libraries from oplide\plugins\ilog.odms.ide.opllang.win32.win32.x86_12.2.0.b13_20100520144800 directory.
    If both fail then I suspect there is something in your PATH or installation that gives problems.

    You may try to first focus on oplrun, using the depends program to see what exact dlls it depends on.

    dlls should be resolved to bin\x86_win32 ones.

    Hope it helps,
