ZWCAD would not start, only staying on the loading screen.
The “VC++” components that ZWCAD relies on for operation are either not installed or the installed version is incorrect, which prevents ZWCAD from starting up.
1. Open Apps & features in Settings->Apps to uninstall Microsoft Visual C++ from your computer.
2. Right-click ZWCAD installation package, select Extract to “ZWCAD_202x_Eng_Win_64bit\”.
Open extracted folder and find the Prerequisites as shown in the below path, click on vcredist_2010 and vcredist_20152019 to install .exe application.
