I'm receiving an Unhandled Exception error when launching ACE to try new liveries.

I've tried launching normally.
I've tried launching as administrator.
I've tried launching normally with antivirus shields disabled for 1 hour.
I've tried launching as administrator with antivirus shields disabled for 1 hour.

If I click Continue the program launches and I can see liveries but they fail to install when I click download. Another Unhandled exception occurs after that.

ps. Thank you developers for a fine product thus far. I'm enjoying the 767 II

Thank you!
Pls copy and post the entire error message (ctrl+C)

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

After launching the ACE, what exactly are you doing, step by step?

I don't get that far before the error pops up.

1) Launch ACE
2) Error presents itself and waits for prompt to Continue or Quit.
3a) If I quit, the program doesn't finish launching.
3b) If I Continue, ACE finishes loading and gives the option to download 767 liveries from a pulldown menu. If I proceed to download, more errors like the one above occur and the livery never installs. So even though I can Continue from the first error, the program doesn't fully function or recover.

It looks like you're on to something here. I removed the 2 manually added aircraft paints and ACE opens without an error now.

Thanks!

Add the following strings to your [fltsim.2] section

model=
panel=
sound=

Thank you kindly - great support!
