When attempting to add in dimensions from the Advanced Dimension Editor you get the following error:
This error is being thrown because of a bug in the 64-bit version of the Jet Data Manager that is installed.
To fix this issue you can install the 32-bit version and use that to add in the dimensions. Or the second option is to upgrade the JDM to the latest version. You can download the latest version from our website here: https://www.jetreports.com/support/product-downloads/
