For new users, navigating the software acquisition process can be confusing because there are different pathways depending on your intent (testing vs. purchasing). Here is the step-by-step breakdown.
| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | Installer fails to launch | Corrupted download or antivirus block | Verify file size; disable AV temporarily; redownload. | | License activation error | Wrong key or internet proxy | Double-check key; configure proxy in License Manager. | | VE crashes when opening a model | Outdated graphics driver | Update GPU drivers (especially Intel/NVIDIA). | | Apache simulation fails | Incomplete installation of C++ Redistributables | Run the vcredist_x64.exe inside the installer folder. | | “Unable to find VE installation” | Windows registry error | Reinstall using “Repair” option. |
