How do I unlock/decrypt my RSDOC design that won't open anymore?

You may have locked your design from further editing but in isolated cases, this could also encrypt the file's contents from being re-opened by DSM.

If you face this situation where the RSDOC just won't open, there is a way to unlock the design:

1. Using 7-Zip or another file archiver, extract the RSDOC. You will see the contents in a similar format:

2. Open the 'SpaceClaim' folder and then the 'document.xml' file in the Windows Notepad program.

3. Using the Find tool (CTRL + F), look for this text <monikerOriginalToReplacements_Values /><locked>True</locked>

4. Now, change the value from True to False : <monikerOriginalToReplacements_Values /><locked>False</locked>

5. Save the file (CTRL + S) and close it.

6. Go back a folder. Select all these contents and right-click on them. Click on Send to -> Compressed (zipped) folder

7. Finally, rename this new ZIP file along with the file extension to 'your preferred design name.rsdoc'

Check that this updated RSDOC opens in DSM.
