Alternatively, you may see the message 'SpaceClaim has stopped working' before the program crashes. Try the fix below:
If DS Mechanical has previously been working properly but suddenly fails to launch without any error messages, there may be an issue with the user configuration file:
Please delete this file and launch DS Mechanical again. The software should then work fine.
64-bit DSM users only:
If you are using a 64 bit version of software, uninstall it and use the 32 bit version. This should also solve the 'SpaceClaim stopped working' error.
version 2.1 (32 bit download): http://eda.designspark.com/receiver/dsm_dl.php?v=32&loc=eng
