I am having trouble running DataWarrior on Windows 7 Professional. When I run the executable, this fatal error pops up:


I read this thread (DataWarrior on window7 Pro) and I have tried freeing at least 1.2 GB of RAM before running DataWarrior again. This worked for one of my computers, but not for others.

I have checked my Java version, which is 32-bit Version 7 Update 80.


I have tried running both the 32-bit and 64-bit versions of DataWarrior with at least 1.2 GB of RAM free, but was unsuccessful.

Please advise.

Hi Kevin,

to me this looks like a memory problem. On Windows DataWarrior 32-bit requires a free block of 1.2 GB memory to start. I assume that even if your system claims you have 1.2 GB or more of free memory, this memory may be fragmented that it cannot be used. You may try to starting DataWarrior just after reeboot. Or, which may not an option for you, I recommend using Linux (e.g. Centos or Ubuntu) for old (and new) computers, because Linux uses resources more efficiently, typically runs faster and more stable and definitely causes less trouble with DataWarrior. You could easily finetune the amount of memory according to needs and availability.

Best wishes, Thomas
