A family of Microsoft relational database management systems designed for ease of use.
For what it's worth, I have tracked the issue to VBE7.dll in C:\Program Files (x86)\Common Files\Microsoft Shared\VBA\VBA7.1.
Some PCs will not open a Access RT application after the update in question .However, replacing this DLL with an older one from Last November seems to fix the issue. I have applied this fix multiple times now with good results.
I am not sure why some PCs experience this issue but when it occurs, replacing the dll has worked every time so far.
Please don't do that, it is not always safe to mix and match dlls.
