I need to know about this error. Need your help.
Thanks.

After reading the detailed report generated by the apple mac os, it seems that you are trying to run a different form of truecrypt on your mac OS. If your mac OS is 64bit then you must have the 64bit version of the truecrypt.
The report shows that you are using a 32bit(x86) version. It also says that you might need to reinstall the software. Because there is a chance that it needs the 64bit version.
If you still get the error, then send an email to their customer support and they will see about that.
