How can I solve the error "Failed to create java virtual machine" when trying to open OpenLCA?

Question

I cannot launch OpenLCA anymore, as I get a pop-up "failed to create java virtual machine". I had closed OpenLCA because had to allocate more memory to OpenLCA after getting a message saying to do so.

Many thanks for your help.

Answer 1

You cannot allocate more memory than your computer has available when openLCA starts. The allocated memory is entered into an openLCA.ini file which is basically a text file. It is in the same folder as openLCA.exe. Try to find it, open it, and in this file, search for

-Xmx12345M

12345 is the allocated memory in MB (hence "M"), so here 12.345 MB, and in your case numbers will be different. Change this to an amount feasible for your computer, then save and restart openLCA.

I am facing the same problem.  How do I know which amount of memory is feasible for my computer. also, how to restart openLCA?

What if you do this and still doesn't open? I have increased the memory allowance 10 and 100 fold and the same problem pops up again.

Perhaps this is not an issue with the size of the memory, but you can try replacing the corresponding ini file from the installation package to resolve it.
