4.3. Can I Uninstall Earlier Versions after Installing Release 6.x or 7.x of Palisade Software?

Applies to: All products, major upgrades to releases 6.0 and newer

After upgrading my software, I notice that the old icons are still there, and the old version still shows in Control Panel » Programs and Features or Add or Remove Programs. Can I uninstall it?

When the first digit of the release number changes, we call this a major upgrade. When you perform a major upgrade, such as 6.x to 7.x, each major version has its own files and folders and will not interfere with the older version. If you want to free up a few hundred megabytes of disk space, you can uninstall the old major version in Programs and Features or Add or Remove Programs.

An upgrade where only the second or third digit changes is a minor upgrade. A minor upgrade will overwrite the earlier version, for instance when upgrading from 7.0.0, 7.0.1 or 7.5.0 to 7.5.1. So you can't have two 6.x versions or two 7.x versions on the same computer.

Does that mean I can continue running old and new major versions in parallel?

Yes, but not at the same time, not even in different copies of Excel. If you have the old major version in Excel's list of Active add-ins, remove it so that it won't start automatically when you're trying to run the new major version. When you have no more need for the old major version, you can uninstall it in Control Panel without disturbing the new major version.

Because you surrendered your old license when getting the upgrade, there are some restrictions on the old version after your upgrade. While you can continue running the old major version on the same computer where it was already activated, you can't transfer it to another computer or reactivate it for any other reason.
