This is totally nuts. I also face the same issue. They should have said that InDesign files are not backward compatible. Instead of telling me that some plugin is missing, Adobe should have simply said file version incompatible. This is Crazy Insane.

You must be a newish user. This is the same stupid and misleading (but apparently technically correct based on how ID checks versioning) error message that's been used for at least the last 4 versions. I think the error message has finally been changed in CS6, but since there are so far no CS6.5 file available you won't see it for awhile.

Actually, the maintenance release of CS5.5 (7.5.3.333) last month backported this fix. So you'll see this opening a CS6 file in the current update of CS5.5:

Actually have been using the product back from when it was Pagemaker – but was the solo user in the office until this year so this is the first time I have encountered any issues.  But now I know!

InDesign was never Pagemaker.

I stand corrected – I started on Pagemaker and moved to InDesign which would still open pagemaker.

My comment about being a newish user was directed at Lian Tombing, but your comment about being a solo user makes some sense. If you never open a file provided by someone else the odds that you'll ever see a file saved in a newer version than you have installed are a lot smaller.

Well, I have been using InDesign since the CS2 days. But was not catching

up with the versions. Exporting it to IDML file solves our problem

Certainly didn't mean to offend anyone (and the smiley was supposed to make that clear). My apologies for any misunderstandings.

It’s all good here! No offense taken.

Dear Peter,

I have 2 files which I think these are newer files. Can you open these files and save them as Indesign 5.0?

greets,

Marius

I just sent you an upload link...

So. I've read through this thread, and what I've gathered is that there is no possible way to open a CS5.5 document in CS4, correct? I have a client who sent me a CS5.5 document, but I'm getting error messages, and can't open it in my CS4. Help?

If you're dealing with client documents, you probably need to keep some semblance of currency. CS4 is long in the tooth at this point, as is CS5. You can ask your client to export the file in IDML format, and then you can read that in CS4. Alternatively, you can download the CS5.5 (or CS6) free trial and do this export yourself. Or you can supply your document to one of us here and we can do the converstion to IDML for you.

Note that new features won't be rendered properly and there is always a substantial chance of text reflow.

Bob,

I'm having a similar problem maybe you could help with? I have a (large) file that was created on a trial version of either CS5.5 or CS6 - the file is labeled as a CS5.5 on the desktop icon. I have tried to open it since then with both CS5.5 (full version) and CS6 (trial version) and get a similar plugin error for both. I have tried uploading the file to adobe creative cloud and am able to view it, which makes me think it's not the file itself that's corrupt...but not sure. Can you shed any light?

What plugin error are you getting?

See Adobe Forums: [Ann] Identify Your InDesign File for a script tha can identify the version for you.

I am having a similar issue. This document was created on CS5.5 and we are attempting to access it on the same version and are having the issues listed below.

Upon opening, it says

"Missing Plug-ins

SMD Jobs Model.sdk.InDesignPlugin

SMD Imposition Model.sdk.InDesignPlugin"

! The document "Northside..." uses one or more plug-ins which are not currently available on your system. We strongly advise you not to open the document. Do you want to open anyway?

When I go to package the document, this shows up:

"This document cannot be packaged due to missing plug-ins. Please install or activate these plug-ins: SMD Jobs Model.sdk.InDesignPlugin; SMD Imposition Model.sdk.InDesignPlugin."

Any help would be appreciated Thanks!

Your case sounds like the file was created using some third-party plugin(s). If the file willactually open without them, you can export to .idml to remove the plugin info, then resave that as a new .indd.

Thanks! Gonna give that a try and get back to y'all!

I am having the same issue and I tried this and it didn't work.  I can now only open the file by opening InDesign>new>template and then I find the document and it opens after a series of pop ups saying that I am missing plugins. If you know of anything else that may help I would greatly appreciate it!

I take it back I restarted everything and tried again and it worked! thanks so much!

I'm in a bind. I need to open  CS4 file and save it as an .inx so I can use it in my older version of indesign. Can you help me? One file. Pweeeeeease.

added: I have the same problem as everyone above.

I have a cs.5.5 and today i was opening a file sent from a friend and i couldn't . The message told me that i have to upgrade my plugins.

I am looking online for understand what is the best move, and i have couple of questions:

upgrade your adobe indesign

or

upgrade adobe plugins

I am pretty new on this so i am confused, are those plugins free?

Please somebody help,

thanks

No, you have to upgrade to a newer version or ask the file provider to send you an IDML file as the file was created in a newer version, as there are now CS6, CC and CC2014.

If you like, you could find out the version of that InDesign document by using the script Identify.jsx by Jongware:

[Ann] Identify Your InDesign File

The results, an alert message, for the CC versions could be:

"CS7" (should be translated to InDesign CC version 9.0)

"CS7.1" (should be translated to InDesign CC version 9.1)

"CS7.2" (should be translated to InDesign CC version 9.2)

"CS8" (should be translated to InDesign CC 2014 version 10.0)

"CS8.1" (should be translated to InDesign CC 2014 version 10.1)

"CS6" will be InDesign CS6 version 8.0 of course.

Uwe

Yes i got the idml version, but i was hoping to find a solution to avoid the same stress in the future.

There is an upgrade i can do, or do I need to get the CS6?

You will always have this problem trying to open a newer file than the version you use. CS6 itself is now two versions behind.

Hi Bob,

I have the same issue with opening my file in CS5. Is it possible to convert my current file to CS5 compatiple format so I could open it in my CS5?

Thanks in advance,

Natalya

Same answer it has been since the beginning -- the file needs to be saved as IDML from the version used to create it. The greater the version gap, the more likely things are to change as far as what you get back in the conversion.

CS5 files should open just fine in CS6. This thread is about going backward, not forward.

of course..but the problem is that I don't have that version anymore =0). It was a trial version of InDesign (downloaded 2-3 months ago) and I'm not sure, even, what # of that version I had. Now I have CS5 and I'm not able to save the file as IDML...However, I tried to rename the file from indd to IDML in Win Explorer but it doesn't work.

So, is there any other solution to this problem?

I'll convert a single file for you, but not lots of files. I'll send you an upload link via private message.

Actually without the snark, this is a thread about workflow compatibility. If you run into the problem for ANY reason, it decreases the end experience for the customer/user. Providing an answer sans, the snark makes everyone get more including Adobe. Yes I do realize a three month old post is not relevant, but I pretty much guarantee that you will be having people on this thread until the reverse engineering of files from later versions to earlier versions becomes easier. Also yes, If PDF's are not a part of your work flow, you are doing it wrong. Nobody wants to receive .indd files from a printers perspective or get one from a client.

With Creative Cloud, assuming you are on line, if you try to open a later version with an older one, you will be asked if you want it converted. If you do, it will be uploaded to an Adobe server, converted and opened for you.

Not sure it gets much easier than that.

As for non-subscribers, packaging a CC file now includes the possibility to create and include an IDML and PDF at the same time.

I was actually looking to open a working file created in 6, with four, but thanks I found my own work around. Statement still stands. Your CC statement Is null and no help whatsoever. Further the three title pertains to 5.5. Thanks for showing up putting in your two cents albeit irrelevant.

Maybe not to you, but we get lots of lurkers here that it might be of help to.

Glad you got things sorted out. Have a lovely weekend.
