Here's wha ya do. As per the AoC forums.
Some users might get an error while installing the game from DVD. It is
possible that the same error is shown more than once during the
installation process.
If you are getting an error window saying:
Quote:
ERROR: Filesize of source file C:\Program Files\Funcom\Age of Conan\RDB\.rdbdata is incorrect |
you should please try the following to fix the issue:
Let it continue to install. Just click [OK] in the above mentioned
error window and setup will continue. in the background. The installer
will keep on installing the game in the background so you will not see
the installer window anymore, you can only see setup is running on the
task bar. You will get the popup saying that the install is done and
you get the option to launch the game as normal. This will work, and
you will be able to patch up. You might, though, get a crash because of
the bad install, and you will get an RDB that is missing resources.
After that please look for the SimpleConfig.exe which can be found in the installation folder of the game
(the default path is: C:\Program Files\Funcom\Age of Conan\).
Start the SimpleConfig.exe
Click on the [verify/repair...]
A window will open. Please click on [Begin] to start the repair process.
After the process has ended you should be able to start the game normally.
