When running a fresh install of Notes Migrator for Exchange build 22.214.171.124 and browsing to license file, the following error message occurs ERROR:Could not load the licensing dll
This is due to the fact that the QuestLicense.dll file is not beinginstalled.
Install Notes Migrator for Exchange (NME) build 126.96.36.199 and than upgrade to NME 188.8.131.52. The QuestLicense.dll file is installed and registered with older builds therefore installing an older build and than running an upgrade will work.
Waiting for a fix in a future release.
