Error message in Windows Event Viewer along these lines:
Faulting application name: DesignSparkElectrical.exe, version: 2018.0.2.25, time stamp: 0x5ab54489
Faulting module name: ntdll.dll, version: 6.1.7601.24168
10 SEPTEMBER 2018: THIS IS BEING INVESTIGATED BY OUR DEVELOPERS.
If you are sending us a support ticket, please include any crash logs generated in this folder: C:\ProgramData\DesignSpark Electrical\TEMP\DUMP
Potential solutions that may work:
1. Launch DesignSpark Electrical.EXE as an admin
2. Temporarily disable Anti-virus software and Windows Firewall (re-enable after launching)
Should the above make no difference, the developers also suggest running Windows in safe mode, it prevents having too many applications running and DS Electrical can run properly, and that's a way to verify program conflict.
