Error launching Insight on 32-bit Windows machine

Error messages

If you are running on a 32-bit Windows machine, you might encounter the following errors when launching Insight:

  • Error occurred during initialization of VM.
  • Could not reserve enough space for object heap.
  • Could not create the Java virtual machine.

What it means

On a 32-bit Windows operating system, you cannot reliably allocate more than approximately 700MB of memory for a single application in the DUG Insight Launcher. This is a fundamental design defect of 32-bit Windows. To solve this problem, reduce the memory allocation or upgrade to a 64-bit Windows operating system.
