Understanding SGR Issues

Common SGR Opening Problems

Electronic Arts SimCity 4 Isn't There

You attempt to load your SGR file and get an error such as "%%os%% Can't Open The SGR File Extension". Usually, this is because you do not have Electronic Arts SimCity 4 for %%os%% installed. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.

Tip: Another SGR-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Electronic Arts SimCity 4 is Out-of-Date

Occasionally, you might have an outdated version of Electronic Arts SimCity 4 installed that's incompatible with your SimCity 4 Graphics Rules File type. Download the latest Electronic Arts SimCity 4 version from the Electronic Arts website to ensure you have the correct one installed. This issue mainly occurs when your SimCity 4 Graphics Rules File file was created by a newer version of Electronic Arts SimCity 4 than you have on your PC.

Tip: Right-clicking on your SGR, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.

Regardless, most of the SGR file opening problems relate to not having the right version of Electronic Arts SimCity 4 installed.

Other SGR File Opening Causes

You can still experience errors opening SGR files even with the latest version of Electronic Arts SimCity 4 installed on your PC.
