Alternatively, you may see the message 'SpaceClaim has stopped working' before the program crashes.
First, try starting the program as an administrator of that PC and make sure any pending Windows updates that require a computer restart are complete.
If that does not work, try the fixes below:
1. 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. Also look for similarly named SpaceClaim sub-folders (ending in a large alpha-numeric string) and delete those too- you may have multiple user.config files from different DSM installations.
The software should then work fine.
The 'AppData' directory may be hidden by default on some computers. To view it, do a Windows search for 'Folder options' or 'File explorer options' and then go to 'view' tab-> select 'show hidden files & folders'.
2. If the program freezes without warning, delete the contents of the C:\Users\"Your Username"\AppData\Local\SpaceClaim\ folder and switch to the Windows 8 (Office 2013) ribbon style under File -> DesignSpark options -> Appearance.
If you have just installed the software and it crashes at first launch, the above config file will not be available. In such cases, please log a support ticket with us through the above button (https://designspark.zendesk.com/hc/en-us/requests/new).
As a pre-requisite with the ticket, please attach the following:
Screenshots from Windows Event viewer which records additional information on the crash (like a faulty Windows module). Please send all the relevant screenshots within the rough time frame of when DS Mechanical crashed. Example:
3. If you repeatedly see a 30 day error message which blocks DSM from opening, check that the time & date on your PC's taskbar is set/synchronized correctly.
Finally, make sure you are online via a direct internet connection when launching DSM and not through a workplace network with strict policies.
4. If you are using Windows 10, try opening DSM in Windows 8 compatibility mode. You can do this through the file properties of the DSM executable.
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.
