Cannot open SE22 file on new MacBook with both AC28 and SE22 downloaded

[Amanda S]

New laptop. Mac. Downloaded AC28 first. Downloaded ACSE22 second. Using Dropbox for storage across devices. I can open a new file in AC22SE but not an existing file. Tried taking file to Desktop in case DB was the issue. No luck.

SE22 (I assume means Start Edition or Solo Edition?) can not open any file that is created in a version newer that SE22.

Sounds like your existing files are newer which is why you can't open them but can start a new file.

Also make sure you have full read/write permissions to all Graphisoft folders (program folders and data folder in your user profile).

Thanks for replying Barry.

I had changed the permissions but the file I had tried was having issues with Dropbox so that didn't help. All the files have defaulted to AC28 on the new computer so each one needs manually changing too... unless there is a quicker way? The less complicated file I tried worked when I changed permissions. Thank you.

I don't know anything about Macs.

The files may show as being 28 files, but that is just because that is the default program that will open them if you just open the file directly.

There is no need to re-associate the files with any particular Archicad version.

22 will only open files up to version 22.

28 will open all files from about version 18 (I am not 100% sure) up to version 28.

When you open a file from the Archicad 'browse' option, you should be able to see the actual file version.

If it is newer than the version you are running, it will not open.

If indeed your Mac is new, then it is running Sequoia.   22 would be running in Rosetta emulation mode since it is an Intel program… but according to the knowledge base, it should not even be able to run at all:

And to repeat what Barry said… you cannot associate a file type with more than one app… the OS has no way of knowing that some version of the file requires a specific app,   Best practice is to never double click an Archicad file to open it but to launch the desired version of Archicad and then open the file from there.

if your files are actually in Dropbox rather than being copied from there to your local storage (in a folder not automatically backed up to iCloud or any other cloud storage), that could be part of the problem too.
