File Associations Problem - Older Installs Open PLNs

Anonymous
Not applicable
My office has used ArchiCAD since Version 7.0 and often I need to load and print older projects. I have versions 8.1 through 11 installed on my machine. Regardless of which order I install the different versions, windows seems to randomly pick a certain version to associate PLN files with and will always try to open them with that version.

Example: If I browse with Windows Explorer to a version 11 pln, and double click, ArchiCAD 9 opens and then gives me an incompatible version error. Right clicking and selecting 'open with' does not fix the problem (I assume because all versions are just named archicad.exe). Is there any way to make ArchCAD 11 the default application for opening PLNs while other versions are installed?

and that's it
I've got this problem, too. I just recently had to install AC9 to open some old Plotmaker .LAY files (wish list item... allow ArchiCAD to open older file types, perhaps with a "goodie"). Anyway, I went to do the "Open with..." thing, but ArchiCAD 11 is NOT a choice. When I manually browse, and select the AC11 application, it still only opens with AC10.

If I had time to burn, I'd mess with the registry. Any of you programmer guys know how to fix this? I imagine you're all on vacation, now that AC12 is out.

I am also having this problem. I have updated to 12. But the pln extension is still associated with ver 11. It's very annoying. Maybe it's not the "right" way to start archicad but it is often the convenient way. When I try to change pln to associate with ver 12, ver 11 is listed as the default, when I browse to archicad ver 12 in the archicad 12 folder, select "archicad.exe" in that folder, the only option I have to take is "open". I select that option and archicad pln extension still defaults to version 11

Try changing the name of the archicad.exe in the AC11 folder and double click a pln to see if it works. Afterward you can change it back.

The safe way is to always start the application first, then use the File>Open menu command.
It's the price to pay for having several working versions installed.

Oh well. I'm probably too picky. I may even go to the extreme of uninstalling 11 getting the pln association set to 12 and then re-installing 11.

Interesting. On the Mac, the association always defaults to the last installed version. So you would do the opposite.

Ordinarily it does default to the latest installation. Theres something strange going on, for some reason when I installed 12 it did not get the chance to default .pln files to 12.
I am not having this problem with software other than archicad.

I don't believe there's any validity to opening ArchiCAD first, then opening the file. In fact I think it is quite a slow method.

I have every version of ArchiCAD in my quick launch bar, and just drag the files onto the respective version. Unless it is an AC12 version, which is what my pln is associated to, so I just double click the file.

IME Windows will associate the extension with the last ArchiCAD version that was installed.

To permanently change how the file is opened (in Windows):

1. Open a Window in Windows Explorer
2. Go to Tools> Folder Options... and select the Fie Types tab
3. Type in PLN quickly or scroll down to 'PLN ArchiCAD Solo Project'
4. Hit the Advanced button
5. Click on open in the Actions pane
6. Hit the Edit... button
7. Hit the Browse button and browse to "C:\Program Files\Graphisoft\ArchiCAD XX\ArchiCAD.exe"
8. Hit OK
9. Hit OK
10. Hit Close

That's all there is to it. I am sure one of my Mac counterparts could provide equivalent OSX instructions.

Cheers,
