The USPS provides DLL's as well as data updates. While the Data needs to be updated every other month, the CASS DLL's only need to be updated annually.
If you are only using the US CASS data and updating by downloading and running the 360data.zip file, then please disregard this article.
Just the DLL's available here:
You simply download the dll's and manually copy and paste them to the appropriate install directory for whichever product(s) you license, please submit a ticket to support if you'd like to cover on a support call. Below is the default install directory to look, yours may differ if you didn't use the default.
The 5 files that need to be updated are: abbrst1.dll, dpv9.dll,keymgr3.dll,stelnk2.dll, and zip4_w32.dll
matchIT Web: (we suggest stopping IIS before attempting to overwrite the dll's, then restarting after)
C:\Program Files\matchIT Web\website\USAddressingWebService\bin
C:\Program Files (x86)\mDesktop\360ScienceAddressing
*If you are coding to Loqate's dll's directly outside of our integrations then the dll's are downloaded as part of the data update, but you still may need to copy the dll files to other machines if you don't run the install manager on every instance and just update the data folder.
