Figure 2 Abnormal installation log
The error records indicate that an exception occurs when the installation package is running the VBScript.
2. Run the VBScript in the VM in question. An error is displayed, indicating that the VBScript engine is absent. Because the installation of PV Driver invokes the VBScript. the installation fails if the VBScript cannot be executed successfully.
