I get the message that access is denied (code 5) to SoftwareIdeasModeler.Core.dll. Had to roll back installation
DLL file was probably locked by system. Please, try uninstall the previous version and then install the new one. (Maybe you could also try to restart your computer, if the file will be still locked.)
By some unknown reason there was an software ideas process running that blocked the dll. After killing it I was able to install.
I'm glad to hear that.
