Hi,

Which version of LR are you using? Is it a very old version?

ACCESS_VIOLATION is usually caused when your script is trying to access uninitialized variable. Try doing the following to resolve the issue.

1. Comment a line on your script which deals with any kind of variable

2. Now check if you still get this error

a. If yes, goto step 1 and comment the next line which deal with variables.

b. If no, great!!!

Often ACCESS_VIOLATION is caused to scripting error.

Mostly these are caused due to insufficient access rights. Take admin rights from your system administrator and try again.

I'm with Suresh. A good 90% of these issues can be resolved by
checking the installation requirements for the tool (without regard to
vendor) and then matching them against what you have in place in your
environment. Mismatch OS, Browser, access rights, aggressive use of
anti virus, etc... can all compromise the system in such a way that
oddball tool issues crop up.

I believe this is related to the variables been handled incorrectly...
Are you using any char /int /arrays in your script? If so, double
check the usage of it.. If you have assigned in wrong parameters,
these errors are prone to pop-up...
