Bob's track builder won't let me make anything

dance1211 · Apr 11, 2014

When I start up BTB, I get a pop-up saying

"Attempted to read write protected memory. This is an indication that other memory is corrupt."

The Xpacks window shows up after this and none of the cameras are active in the main screen. If I try to make a new track then I get

"Unhanlded exception has occurred in your application. If you click Continue , the application will ignore this error and attempt to continue. If you click quit, the application will close immediately.

Object reference not set to an instance of an object.

I tried reinstalling BTB and DirectX but none of this is working.

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.

The error isn't specific to BTB. It can happen to other programs written in the same language. I did a quick search on Google and one promising suggestion was that you might not have the correct version of the .NET framework installed. BTB should install the correct version when installed, but something could have gone wrong.

I think BTB requires version 2.0. You can check what versions you have by following these instructions:
http://superuser.com/questions/173367/what-version-of-net-am-i-running
On my computer I have v2.0.50727

You can have multiple versions of .NET, and BTB's documentation might be out of date, so if you have v2.0, try getting the latest version too.
