Step-by-Step Transfer InDesign files to Affinity Designer (via Viva Designer 10)

For the short term, I'm focusing on using Viva Designer 10 to convert my old .indd files to .idml so that I will be able to access them in Affinity Publisher.

Here's the step-by-step instructions on how to do it:

1. Go to this page and download Viva Designer 10 (click on the button at the top of the page to switch from Viva 11 to Viva 10): https://viva.systems/service/downloads/
2. Download the FULL version (not free).
3. Install software.
4. Open software: You will be told how many days you have left in your trial
5. To open the InDesign file (that ends in either .indd or .indt), you must either:
1. Drag-and-drop the file into the open software to open it; or
2. Select File > Open and then modify the doc type to "All Readable Documents."
6. The InDesign file will open.
7. Check it out to confirm that it looks right (in my tests, I had to relink images and install some fonts). 
8. Then you go to File > Export > Documents...
1. This will give you the option to export the file as an IDML file. This stands for INDesign Markup Language. This is a format that other programs, including Affinity Publisher, can open.
2. Export the file.
9. Open the file in Affinity Publisher.

You're good to go!

NOTE: I am suggesting you use the older version of Viva Designer because it actually worked for me. When I tried Viva Designer 11, it did not work.
