There is not a separate installation required to go from Sage 100 xxxx to Sage 100 xxxx cloud/100c (same version). If you have Sage 100 2018 installed, you would enter the new Sage 100c (100cloud) product keys in registration and it unlocks the features within the product for Sage 100cloud/100c.

Note: some additional components available via Sage 100c/100cloud subscription would need to be separately installed or purchased (such as Sage Inventory Advisor Basic, Sage 100c Manufacturing, Sage Contacts, etc.) and may require a specific version of Sage 100/100c installed (i.e Sage 100 2018.3 and higher).

Additional Nores:

In some cases, new Sage 100c/100cloud product keys were registered but then got error that feature was only available with subscription. If the user has proper Role settings to allow, in several cases the Sage partner was able to re-register the same product keys and then features were available.

Sage 100 2022 - some features previously requiring a Sage 100c/100Cloud subscrtiption were made available without this subscription. Now available in SAge 100 20220 for subscription and non-subscription customers:

• Document Date Warnings—Displays a warning when a user enters a date that is outside of the new settings defined in Company Maintenance.
• Spell Check—Seamlessly auto-correct misspellings and add terms to your custom dictionary.
• ALE Full Text Search—Facilitates a full text search engine.
• Theme Maintenance—Use a predefined theme or create a custom theme for your desktop.

NOTE: before making changes to the Registration information, either take a screenshot of the existing information or note the details (in case prior registration information must be restored).
