Hey guys...
I'm revisiting an old installation of MAME I have but can't remember if it's a 32bit version or a 64bit version. Is there an easy way to quickly check which one?

The only real way at the moment the actual executable. MAME64 is been the filename for all 64-bit MAMEs as far back as I can remember. If you are unsure, download the official binaries of the version you have (should show when you run it, or use -help) and compare benchmarks. If it is prior to version 0.120, MAME did produce 64-bit official binaries before that version.

Which OS? Do you have an POSIX-like environment available? As others have said, on Windows you can run it and check Task Manager. If you have a POSIX-like environment, you can use the file utility:
On Windows with MSYS2:
Code:
$ file build/mingw-gcc/bin/x64/Debug/sdlmame64d.exe
build/mingw-gcc/bin/x64/Debug/sdlmame64d.exe: PE32+ executable (console) x86-64, for MS Windows
On Linux:
Code:
$ file build-clang/linux_clang/bin/x64/Debug/mame64d
build-clang/linux_clang/bin/x64/Debug/mame64d: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/l, for GNU/Linux 3.2.0, BuildID[sha1]=bfd4c8fc389501e64a8e6f66c2356b6ad218e7ab, with debug_info, not stripped

Many thanks gentlemen. You're right....the executable will have "64" after the name if it's 64 version. Not sure how I didn't notice this. And yes, I'm on Windows 10. Task Manager indeed indicates it as well. Versions of MAME I was wondering about was 0.193, a few versions of 0.199.
Got it sorted now. Happy Holidays
