Unable to open RH2020 projects after upgrade due to Application Errors.

Unfortunately I didn't see the message regarding upgrading through Help until later on. After I started getting issues I completely uninstalled RH2020 and re-installed it with the latest release.

I have now upgraded the project from Classic 2019 to 2020.3 and it completed with just one warning message:

Failed patching and copying CSS Dependencies from D:/Robohelp/Robohelp Classic Projects/One Revisions/dist/bootstrap.min.css

I closed and re-opened the project and have had no errors this time.

So the project did upgrade OK but then you tried to upgrade from Check for Updates. That doesn't work though from 2020.0 as explained in the Featured topic on this site. Later did you uninstall and reinstall or just installed 2020.3 over the top?

Regardless though try upgrading from Classic again as per our offline discussion.

I had a project open in 2020.0 (can't remember which one though). I clicked on Help | Check for Updates to upgrade to 2020.3 and got a conflict message which said to close the open program. Did as the message suggested after which it continued to upgrade to 2020.3

After that had finished I started RH again and opened this project as I needed to make a change, got the upgrade message as per the screenshot and then the application error.

The version installed at the moment is 2020.3.32.

Let's clarify when the upgrade went wrong. I was thinking you had a project in 2020 format that was giving this message when you upgraded to 2020.3 from an earlier version of 2020. Maybe it is occurring when you upgrade from Classic to 2020? If so, do you have 2020.3 installed?

I still have classic 2019 versions of all projects so I could always upgrade a copy of that to 2020.

OK I will check it out but do you have an earlier backup that will open? Don't do anything with it, I just want to know what the options might be.

Sure, I can send you the project.

Interestingly, I have discovered that other projects will now open and upgrade without error (which didn't happen yesterday so something has changed). However, even a fresh copy of this project still has the same error so there must be something in particular that the new release doesn't like.

I will send a copy now.

Can you share one of the projects? If you can, then see the Contact page on my site and send the project as instructed there. Do make sure you include a link to this thread and please do not email the project direct.

Have deleted contents of .rh folder and re-opened the project. Still get both the upgrade and application error messages.
