Issue Description
At a site, installing the PV Driver on a Windows 2003 virtual machine (VM) fails and returns an error message.
Figure 1 Error message returned during the installation of the PV Driver

Handling Process
1. Find the wsh.inf file in C:\WINDOWS\inf of the VM, right-click and choose Install from the shortcut menu.

2. Click Start and then Run. In the window that is displayed, enter the following command:
regsvr32 urlmon.dll shdocvw.dll jscript.dll vbscript.dll /s

3. Restart the VM, and install the PV Driver again. The installation succeeds.
Root Cause
1. Find the installation log of the PV Driver in C:\Documents and Settings\Administrator\Local Setting\Temp. Compare it with a normal installation log. It is found that the abnormal installation log contains two error records.

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.
The installation of PV Driver invokes the software installation frame of Windows and uses some tools or services of Windows. If any of these tools or services becomes abnormal, the installation of PV Driver is affected.
