Now that Microsoft recommends the 64-bit version of Office (beginning with Office 2019), converting VBA for 64-bit compatibility should now be a medium priority for you.

When Microsoft recommended the 32-bit version of Office (through Office 2016), converting your VBA code for 64-bit compatibility was a low priority. I still had a laptop with 32-bit Office that I could use for emergencies and applications that I could not upgrade due to 32-bit library dependencies.īy forcing myself to open every application in 64-bit mode, I was confronted with the errors. I installed 64-bit Office on my main development machine. I had to do something to force myself to convert my applications for 64-bit compatibility. I proved the concept and then did nothing about it for years.įinally, I realized that if I waited much longer I was going to run out of runway. I started converting one to run in 64-bit mode, but there was no urgency. I set up a virtual machine and installed a 64-bit runtime to test my applications. But none of my clients were running 64-bit VBA. I knew for years that 64-bit VBA would supplant 32-bit VBA one day.

Bite the Bullet: Install 64-bit Access on Your Dev Machine Of course, those versions of Access are waaaaaay out of support now. * Actually, if you still have a copy of Office/Access 2003 or earlier, you CAN install that side-by-side with a 64-bit version of Office. Unfortunately, installing a 32-bit Access runtime alongside a 64-bit version of Office simply DOES NOT WORK.* That was annoying, but at least it was an option. The 2007+ versions of Office/Access would spend a minute or more rewriting registry entries at startup if you switched between versions. Things started to fall apart with that approach around the time Office/Access 2007 was released. As long as you started by installing the oldest version first, everything worked pretty well. There was a time in the not-too-distant past when you could safely run multiple Office versions side-by-side. Yes, that would be very nice if it worked, wouldn't it? What If I Install a 32-bit Access Runtime Alongside 64-bit Office? What's more, if you insist that your users install the 32-bit version of Office, you will need to explain the explicit extra steps they will need to take to run the non-default Office install. Up until Office 2016, you could tell your clients that your Access application only works with 32-bit Office and, oh by the way, that's the version of Office that Microsoft officially recommends you install.īeginning with Office 2019, that argument no longer holds water. If your approach to the arrival of 64-bit VBA has been to keep your head in the sand and pretend it does not exist, I have some bad news for you. Can't I Just Ostrich This Thing a Little Longer? Philipp Stiefel has the most comprehensive tutorial for upgrading API declarations at: Windows API declarations in VBA for 64-bit. You can't simply do a find and replace of Long with LongPtr in all of your Declare statements.

There is no across-the-board rule for how to update every API declaration from VBA 6 to VBA 7. However, if the VBA 6 Long argument actually refers to a memory address, then the argument should be declared as a LongPtr in VBA 7. If the Long argument of an API function represents a plain old number, then it should remain declared as a Long integer in VBA 7. All memory addresses were 32 bits long.īeginning in VBA 7, you can begin to update your API declarations. In VBA 6 and earlier, there was no need to distinguish between a long integer that referred to a memory address and a long integer that referred to a plain old number.

VBA 7 introduced a couple of new data types to handle this situation:

In 64-bit VBA, those memory addresses are 64 bits long. In 32-bit VBA, those memory addresses are 32 bits long. Many API calls include arguments that are pointers to memory locations. While there are several compatibility issues to be aware of when updating your code for 64-bit VBA, one of the most common is the requirement to update your API declarations with the PtrSafe keyword. API Declares Require PtrSafe in 64-bit Mode That default setting changed to 64-bit as of Office 2019/Office 365/Microsoft 365: For Office 2019 and 365, the default installation mode is now the 64-bit version. For Office 2016 and earlier, the default installation mode was the 32-bit version. As recently as Office 2016, Microsoft recommended installing the 32-bit version of its flagship office suite.
