My fix for the "Updating Executable" issue

[PolarPaladin]

============================================================
On the Steam page, go to Civilization V and right click. Select “Manage” then go to “Browse Local Files”

In the Civilization V folder, if you are on Windows 10, Alt+Shift+Right-Click on the desired exe. If you are on Windows 11, just Right Click.

Select “Copy As Path”

Back in Steam, Right Click on game and select “Properties”

Paste the copied path in the “Launch Options" text box. This path must be in quotes.
After pasting the path, press spacebar and then type %command%. There must be a space between the end quote and the first %.

If you've installed Steam and the game to the default location, it should look like this:

"C:\Program Files (x86)\Steam\steamapps\common\Sid Meier's Civilization V\CivilizationV_DX11.exe" %command%

For me it was like this:

"E:\SteamLibrary\steamapps\common\Sid Meier's Civilization V\CivilizationV_DX11.exe" %command%
