The following error messages may occur when upgrading from an older version of Lumerical software. Typically it is possible to simply install the new version without manually un-installing the older version first. However, in some cases the automatic un-install fails, resulting in these errors.
There was a problem loading the activation library. Code #.
Such problems can be resolved by:
- Close the error message by selecting ‘NO’.
- Open the
Control Panel > Programs and features, and un-install the software (ie. FDTD Solutions)
- Go to
C:\Program Files\Lumerical\and ensure the product folder (i.e. FDTD) has been removed.
If it is still present, delete the entire folder.
- Reboot your computer
- Re-install the new version of the software.
