I just blew a couple hours on this.
The MODIFY INSTALL post from above works, BUT windows is going to ask for a file you may not be able to find. It wants the MSI file so it can get the GA5SE version of the expansion. The download is an EXE, so I was like “what? where?” and searched 8 TB of hard drives…nada
First, go download and install WINRAR (Other archivers may be able to do this, I don’t know). Be sure to enable the option for shell/explorer integration.
Here’s what I did to fix it (Windows):
Go find your .EXE download file METAL_ESSENTIALS_INSTALLER_win.exe
RIGHT CLICK it and choose Open with Winrar
Find the .MSI file and right click, choose Extract to specified folder
Choose a folder to put it in, and remember it.
NOW, go do the above steps, repeated here:
Go to “ADD or REMOVE PROGRAMS”
Find the METAL ESSENTIALS entry
