Archicad 17 for 32 bit systems

Anonymous

Hi all

im trying to install AC17 on my laptop which runs on WIN8 32bit
I know that officially it supports only 64bit systems but is there a workaround that?
do Graphisoft really don't intend on handing a solution for that?
what about all the AC16 users who want to upgrade but don't want to start from scratch with their OS?

best regards

There's no work around.

If I remember correctly when AC16 came out GS informed that it was going to be the last one compatible with 32bit processors.

Yes, as Eduardo says, the discontinuation of support for 32-bit systems was announced a year ago to give people plenty of time to upgrade their OS or system, or to make sure that they did not purchase a new 32 bit system.

This only affects Windows users, as Mac OS X is 64 bit.

I sympathize that you apparently purchased or upgraded to Windows 8 32 bit after Graphisoft had made this announcement, which was designed to help make sure that people only purchased 64 bit OS in preparation for the release of 17. Worse, I sympathize for the hassle of upgrading to a 64 bit version of Windows after just reading that Microsoft's only upgrade path from a 32 bit OS to 64 bit OS requires a complete reinstallation of all software (and presumably all license activations - so if you do this be sure to de-activate all software first!).

I'm not a programmer but I suspect that having only 64-bit code helps GS to streamline the software.

O.T. Does anyone remember 8-bit DOS?

Only run as an app within Windows NT. No, wait, that was 16 bit DOS (NT was 32 bit only and my Pentium Pro didn't like 16)
