Cannot create .accde in 64-bit

[JohnPapa]

I get,
"Could not use <Specific filename.accdb>. File already in use."
when I try to create the .accde using 64-bit A365.

The .accde is created ok when I use the 32-bit A365.

Both the 32-bit and the 64-bit use the following Version and Build

Wanted to add that the .accdb appears to run ok

Fixed. I was able to create the 64-bit .accde when I disabled the antivirus software, in this case BitDefender.

With the antivirus on on different pcs, the 32-bit .accde is created , while the 64-bit is not.

So if you are having problem with creating .accde, you may look at any antivirus software as well.
