The project I work on is created with RoboHelp X5. One of my
clients is updating his own help for my project and uses RoboHelp6.
Now the project he just sent back to me won't open in RoboHelp X5
anymore. I always get error:
"This project is from a newer version of the program. This
project is no longer compatible with this version. Please make sure
you have the newest version installed".
However I cannot upgrade to RoboHelp6 since other clients are
still using RoboHelp X5. Asking everyone to upgrade is not an
I also tried opening the "hhp" file instead of the "xpj"
file, but that also fails with the same error message. In addition
I then get the message "Unable to create database. Check that the
directory is not read-only."
All the files are on the local disk of the PC (not on a
network drive) and the folders are writable.
Option 1] Hop over to PayPal and send me an obscene amount of
money! I'll come and fix it wherever you are.
Option 2] Delete the CPD file before opening the project from
the XPJ file. It will open and should be OK provided the client has
not done anything RH6 specific, like use variables. There's more
about this in the topic about Opening Projects on my site.
Are you aware that you can run both X5 and RH6 on the same
PC? You have to buy the full version of RH6, not the upgrade, but
they work quite happily together.
