Hello,
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 7.0.0.0 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?

Hello Samantha,
The following is a procedure that will help you resolve that issue:
-
You will need to start your computer in Safe mode and then follow these steps:
-
Restart the computer.
-
And then after the BIOS information has been displayed, you will need to press F8.
-
You will then use the DOWN ARROW key to choose Safe Mode, and then press ENTER.
-
And then use the UP ARROW key and the DOWN ARROW key to choose your computer, and then press ENTER.
-
After that, you will need to log on to the computer as a local administrator.
-
And then you will click Start, click Run, type cmd.exe, and then click OK.
-
Go to the command prompt, and then type msiexec /unregister , and then press ENTER.
-
Still at the command prompt, type msiexec /regserver, and then press ENTER.
-
At the command prompt still you will need to type exit, and then press ENTER to close the command prompt.
-
After that you will get rid of the software program from Add or Remove Programs.
Regards,
Carl
