64-bit or 32-bit Lazarus on 64-bit Windows 10?

bill0287:
I seem to remember that is was recommended to install and use 32-bit Lazarus on a 64-bit Windows machine...is that still true in Lazarus 1.8?

molly:
That depends.

Do you create more often a 32-bit app or a 64-bit app ? That should determine what would be better for you to install.

Thaddy:
Indeed depends. But my new laptop is - almost - 32 bit software free. I consider it legacy for the platform. (although it has merits)
E.g. on Linux you have to explicitly install a subsystem to get 32 bit working on a 64 bit system.

tetrastes:
May be you seem to remember this:

--- Quote ---Current released versions of FPC (2.6.x) do not include support for SEH handling. This can affect the stability of many 64 bit applications. Therefore it is recommended to use the 32bit IDE, and generate 32bit applications only. This will change when FPC 3.0 is released.
Please visit our forums and Wiki for additional information.

If so, this is not true since Lazarus 1.6.
