    Hi, I'm trying to install the DNN 7.4.2 and then add a few template files, data providers from an old dnn version. I  got this error during the install process. Any information regarding this will be helpful. Can provide additional information if needed. Thanks.

      Are you trying to do a clean install?

      Is it possible that you are trying to INSTALL but using an UPGRADE package?

      How far into the install process did it get?

      (These days, I use nvQuickSite for all installs (or at least those for which I have access to the server command line). It keeps me from making mistakes, and sets everything up perfectly.)

        No, I did not do a upgrade, I just grabbed install.zip from dnn website unpacked it and then installed with some other custom templates and data providers. This error looks like the upgrade.upgrade(strproviderpath) in the dnn install.cs component, either did not get a value or did not get required params. Do you know what might cause these issues when installing dnn? I tried to clear cache and do a fresh install but this seems to be coming again.

          Did you Unblock the file before extracting files?
