I recently upgraded to 64-bit Framemaker 2019 from 32-bit Framemaker 2017 and converted my existing files. Unfortunately, the new Framemaker won't talk to 32-bit ePublisher Webworks. Webworks does not currently have a 64-bit version (supposedly it is coming out in July), so I downgraded back to 32-bit Framemaker 2017, but now I can't open my files. Is there a work around or some way to convert my files back to something that can be opened with 2017?
I wasn't aware that there was any difference in the .fm files produced, but you could install the 64-bit on another machine, open the files and save as MIF to be able to transfer them back to the 32-bit version.
[EDIT - I missed the "I'm going back to FM2017" bit when I answered. There's no difference in 32/64-bit FM2019 files. Personally, I'd just use the 32 bit version of FM2019 instead of going back to FM2017]
You have to open the files in FrameMaker 2019 and save them down to 2017. You can only save down one version (32-bit versus 64-bit doesn't matter). If you have a lot of files to save down, check out my ConvertDocs script at frameexpert dot com.
There's also "heroic open" in earlier releases, but it's a last resort.
If the latest FM is available, save back as prior release .fm, or save as .mif.
Whenever a mixed-release environment lurks (such as sending out for translation), stewardship needs to routinely include saving as both .fm and .mif.
Thanks so much for the info.
