OnePager, when launched as an add-in, inherits its system resources from Microsoft Office (i.e. Project or Excel), which means that if Microsoft Office runs out of memory for some reason, OnePager will run out of memory as well.
This is pretty rare occurrence, but when it does happen, there are two ways to address it. The recommended approach is to launch OnePager as a standalone application instead of as an add-in to Project or Excel. This allows OnePager to allocate its own system resources beyond the constraints of Office.
If you prefer to continue running OnePager as an add-in, or if running standalone still presents memory issues, you can do a slight increase to virtual memory, which will give OnePager more "breathing room" in terms of system resources.
Instructions to increase virtual memory on a Windows 10 machine follow. Other operating systems will be slightly different, but will follow a similar process:
On your Windows Start menu, click on the Settings (gear) icon:
In the search box, type "Performance", and then choose Adjust the appearance and performance of Windows:
Go to the Advanced tab, in the Virtual Memory section and click on Change:
Uncheck the Automatically Manage box, and then set a higher Initial Size and Maximum Size than what are currently set. Once finished, click Set and OK.
After restarting the computer, performance should improve, and any memory warnings from OnePager should disappear.
