title: MS-Access 2019 Runtime Or Ms-Access 365 Runtime?
body: <p>I'm planning to &quot;upgrade&quot; the MS-Access desktop application I've developed for various customers with various Access versions - to <strong>Access 2019</strong>.
  That is because of 3 main reasons:</p>
  <ol>
  <li>Bigint support</li>
  <li>Better ODBC connectivity</li>
  <li>New technique for building graphs.</li>
  </ol>
  <p>Now most of my customers run Access desktop applications through Access <strong>Runtime</strong>. And most of them have various versions of MS-Office Standard, say 2003, 2007, 2010 or 2013 etc.
  It is NOT a problem to run excel automation VBA code from Access, and we use it a lot.</p>
  <p>If we plan to use Access 2019 to benefit from all the above advantages - what kind of Runtime am I to give to the customers?
  It's been said in various places that NO Access-Runtime-2019 is been planned to be built. I've talked with a Microsoft representative and he said &quot;Your Access-2019 applications will have to be run on Access 2013 or 2016 runtime, and it is supposed to work just fine&quot;.</p>
  <p>My 3-fold question is:</p>
  <ol>
  <li><p>If an Access-2019 application - which uses the above features - is run with Access-Runtime 2013 or 2016 - will these special 2019 features <strong>really</strong> work?</p>
  </li>
  <li><p>What about Access-<strong>365</strong>-Runtime? Will these features work with it?</p>
  </li>
  <li><p>I've read about the problem to install newer versions of Office in the same machine where older versions exist: The 2016/365 Office uses C2R installation technique, while older Offices use MSI installation technique (<a href="https://support.microsoft.com/en-us/office/office-installed-with-click-to-run-and-windows-installer-on-same-computer-isn-t-supported-30775ef4-fa77-4f47-98fb-c5826a6926cd" rel="nofollow noreferrer">see link here</a>). So my conclusion is that my customers, who rely on the existence of Excel 2007 or 2010, for instance, while working with my Access applications - will have to abandon these 2007/2010 Offices because of the new Access-2019 applications that we plan to give them with Runtime 2016/365. <strong>Is that true?</strong></p>
  </li>
  </ol>
  <hr />
  <p>I <strong>know</strong> users with Office 365 will do fine. My question was about trying to run Access-2019 applications - in <strong>older</strong> environments of MS-Office, like Office <strong>2007</strong> or <strong>2010</strong>. After all, they had paid for those Offices long before Office 365 was developed, and why would they want to change them...</p>
  <p>This post is another clue:

  <p>According to what's written there, Runtime 2016 <strong>doesn't</strong> support Bigint (which is one of the features we want to use Access 2019)! So when the Microsoft representative I've talked with said &quot;Just run it on 2016-Runtime!&quot; - He ignored (or worse than that - didn't know) that Bigint will NOT be supported! So what do we do about it now?</p>
