Legacy Compatibility Installer

to support working documents created from old Systems2win templates

Who needs the Legacy Compatibility Installer?

You should install the Legacy Compatibility Installer if (and only if):

  1. you are using the Systems2win add-in version 12 or higher on a 32-bit version of Excel

    To determine which version of Systems2win you are using:
    Excel > Systems2win menu > Upgrade > About Systems2win Templates

    To determine which version of Excel you are using:
    Follow these instructions

  2. and you want to use a complex legacy working document version 10 or lower

    (and you have decided NOT to migrate data from your old working document to your new template)

Tip: Simple legacy templates can be opened using Systems2win menu > Setup or Upgrade > Open a Legacy Document

If there are no #NAME errors — you can use that template (even without installing the Legacy Compatibility Installer)

If there are #NAME errors — then you need to either install the Legacy Compatibility Installer, or migrate your data.

Tip: Once you have installed the Legacy Compatibility installer, you will never have to install it again on that computer...

even as you install future upgrades.

Tip: To avoid the need to for the Legacy Compatibility Installer in the future...

you will probably want to lay out a plan to migrate data from old working documents

How to install

These instructions assume that your IT Department has not created your own custom installer.
If they have, then follow the special instructions provided by your IT Department, which most commonly will be to simply double-click that one customized installation file.

1) Before you can install the Legacy Compatibility Installer

the licensed (not trial) Systems2win add-in version 12 or higher must already be installed on your computer, following the usual Installation Instructions

2) Download the Legacy Compatibility Installer:

If your IT Dept won't allow you to download an exe file...
      Then you should respect their desire to download and install this exe file for you.

3) Run your installation file

Do NOT uninstall the version that is already on your computer.

Close Excel.

If you accidentally run the installation file with Excel open, you will need to run it again with Excel closed.

If you are logged in as the Target User with Administrator privileges...

simply double-click the legacy installation file (with Excel closed) and accept all of the default selections to complete the installation.

If you are using a different Administrator's password...

Step 1) Run the Systems2win-Legacy.EXE file

Either double-click it, or right-click > Run As Administrator,then enter a valid Administrator username and password,

(perhaps temporarily granted from your IT Department)

Accept all of the default selections to complete the installation.

Step 2) Finish installation


Logged in as the target user — (not as an Administrator)...

Download and run Systems2win-Finish-Install.xlsm

either from Start menu > All Programs > Systems2win
or download here

(Yes, this is the same file to finish installation for the regular installer too)

Finish Install file

4) Test

Open one of your old working documents that was created from a legacy Systems2win template v10 or lower.

Finish the usual installation and test.
