There are some other threads with same issue ... none seems to have a valuable workaround:

Maybe you can send PM to those guys.

Please post workaround when found.

Also if you can post your project we maybe might help ...

I got the issue resolved by setting all the variables to $EMPTY_STRING$ before using them. Although it is a little strange since the exception doesn't explain the actual problem. Install anywhere is looking for the variables to be set to empty before using them.
