When installing nvm-windows, if you supply alternate credentials to gain elevation, the installer will create the user environment variables under the user profile of the credentials you supplied rather then the user profile of the user who originally launched the installer. To get around this I made use of the ExecAsOriginalUser Inno Setup function. This function lets you shell execute under the original user. I was able to call REG.EXE to add %NVM_HOME% and %NVM_SYMLINK% but to handle the parsing/appending of the original path I had to create a VBScript and launch it with ExecAsOriginalUser. I actually created a setuserenv.vbs for the install and unsetuserenv.vbs for the uninstall.
