Over the last few months, I've learned one very valuable lesson: There is NO benefit in Windows 7 unless you go 64 bit! Of course, that doesn't mean that there are many 64 bit applications out there to run on it.
Why is 64 bit so important for Windows 7?
Well, like all new Microsoft Software, it uses a bit more disk space and a bit more memory that its predecessors. Unfortunately, there's a 2GB memory limit in 32 bit windows - and it still applies to Windows 7.
That means that now Windows itself takes up more space but your maximum memory remains the same. Even if you have a PC with 4, 6 or 8GB RAM, 32-bit Windows will only use 2 GB.
Windows 7 64-Bit is a different story but weirdly, the limits aren't imposed by the bit-space but by Microsoft themselves - and it's different depending on which version of Windows you're running;
- Starter: 8GB
- Home Basic: 8GB
- Home Premium: 16GB
- Professional: 192GB
- Enterprise: 192GB
- Ultimate: 192GB
Where's the 64 Bit Version of Lotus Notes
Good question. There doesn't seem to be any answers on this one and even the IBM Helpdesk tech I spoke to yesterday was surprised that it didn't exist. I'm sure they're working on one though.
So.... The short answer is that There is NO 64 bit version of Lotus Notes 8.5.2, you need to use the 32 bit version instead.
But wait .... there's more.
I tried and Lotus Notes was so slow that it barely ran at all.
I've since applied Fixpack 1 and Fixpack 2 and it's back to normal - perhaps better than normal because it's got more memory space to run in (Windows isn't taking a big bite out of the 2GB space).
In reality, I think you only need fixpack 1 but it's good practice to add both.
Another short answer; When using 32-bit Lotus Notes 8.5.2 on 64 bit Windows, make sure that you have Fixpack 1 and 2 installed.
I hope this saves some people a bit of time since it's not quite so clearly stated elsewhere.
(and in the meantime, keep petitioning IBM to hurry up with the 64-bit version)
