Troubleshooting 

Possible Solutions 

You can receive that 421 error if the FTP server you are connected to limits the total 

number of connections available or limits the connections available to one user.  There are 

three things you can do: 

1.  Limit the number of connections to any one FTP site by selecting Tools > Global 

Options > Connection and set "Per site max connections /transfers" to 1 (By 

default it will be set to 2). 

2.  Remove items from the Transfer Queue.  The Transfer Queue is where you see 

items ready for transfer, in transit, or just transferred.  Sometimes the Queue Pane 

can become cluttered with unfinished transfers.  To clear the queue, right click inside 

it and choose Remove All. 

3.  Make sure only one instance of CuteFTP is running on your system.  Open the 

Windows Task Manager and see if CuteFTP is listed more than once.

AILED TO COMPLETE SCRIPT BASED INSTALL

Problem: 

The following error message occurs at run time:  

Error 1628: Failed to complete script based install. 

More Information 

The error message occurs at run time usually when you are trying to uninstall, repair, or 

update an installation. This error message is caused by the Windows Installer Service and is 

often caused by the installation itself. 

Possible Cause 1 

This error message is often caused when the uninstallation log file becomes corrupt. This 

can happen if the installation is somehow corrupt.  

Fix:  End the process that is running IDriver.exe via the Task Manager by following these 

steps: 

1.  Press Ctrl + Alt + Del and select Task Manager.  

2.  Go to the Processes tab.  

3.  Check the running processes for idriver.exe 

4.  If found, select the process and then select End Process. 

Run the installation again to see if the error still occurs. 

Possible Cause 2 

This error can also occur if the Windows Installer Service is not properly configured on your 

computer or if the installation is created with a newer version of the Windows Installer 

Service than what exists on your computer. 

Fix:  To fix this issue, install the latest Windows Installer Service on your computer.
