SC2Mapster

The following information applies to Windows. Tips for macOS can be found here: link.

SCMR installer is currently unavailable and in version 8.0.1 there is no shortcut. Therefore, after making a manual installation, the player must create a shortcut himself. If someone cannot do it, they can try to use the shortcut from version 7.3.1.

The shortcut from version 7.3.1 works if Starcraft is installed in the folder C:\Program Files (x86)\StarCraft II.
If Starcraft is installed in another folder, you need to modify the shortcut.

The original entry in the shortcut is:
"C:\Program Files (x86)\StarCraft II\Support\SC2Switcher.exe" -run "C:\Program Files (x86)\StarCraft II\Maps\Starcraft Mass Recall\SCMR Campaign Launcher.SC2Map" -displaymode 2

The part I marked in red must match the location of the SC2Switcher.exe file.

The part I marked in blue must match the location of the SCMR Campaign Launcher.SC2Map file.
