Description:
Product: Veritas Enterprise Vault Discovery Accelerator -- Error 1720. There is a problem with this Windows Installer package. A script required for this install to complete could not be run. Contact your support personnel or package vendor. Custom action BuildPrereqMsg script error -2146828275, Microsoft VBScript runtime error: Type mismatch: 'CDbl' Line 148, Column 9.

V-437-11720

 

Cause

The root cause of this issue is a script error during the installation process. Specifically, the error occurs due to a type mismatch with the CDbl function in the Microsoft VBScript runtime. This error prevents the completion of the installation and triggers the error message.

 

Solution

To resolve this issue and successfully install DA 15, follow these steps:

1. Open the Control Panel on your Windows machine.
2. Click on the Clock and Region, Region, or Region and Language option depending on the Windows Server version.
3. In the Formats tab, click on the Additional settings... button.
4. In the Decimal symbol field, ensure that the decimal separator is set to a dot (.) instead of a comma (,).
5. Click the OK button to save the changes.
6. Restart the server to apply the regional settings changes.
7. Attempt to reinstall DA 15.

Changing the regional settings for the decimal separator from a comma to a dot should resolve the type mismatch error in the script and allow the installation to proceed without encountering the error.
