SP3, CS5: Cannot open .idml file
Thread poster: ttmk
Oct 11, 2010


First time to use Studio SP3. I just translated an InDesign file, ran verification (no errors), and saved target as .idml. When I tried to open the .idml file, InDesign barked: "Cannot open file [path]. Mismatched tag."

Anyone know how to troubleshoot this?

Many thanks in advance.

Seems to be an incompatible IDML file Oct 12, 2010

We faced the exact same error with one ID CS5 file as well and were not able to find a solution.

We reported this to SDL, who acknowledged the problem and is now working on a solution.

It seems as some IDML files are not properly converted by the new IDML filter. Fortunately, this is not the case for all IDML documents, but when it happens, you are really stuck.



Thanks Walter. SDL, looking forward to a fix. Oct 13, 2010

Thanks for your reply, I hope they find a solution soon.
