I’m receiving the error message “Error 1721
I’m receiving the error message "Error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor." for a MSI I have built using version 126.96.36.199 for Windows 98.
The older version has been removed before the new MSI was installed. I have also tried different settings for the MSI, for example, no mirror drive.
Does anyone know how I fix my MSI so that it starts working?
