Understanding GROB Issues


Troubles Opening GROB Files

Emu48 Removed

You attempt to load your GROB file and get an error such as "%%os%% Can't Open The GROB File Extension". When this happens, it is commonly due to Emu48 missing in %%os%%. This will prevent you from double-clicking to open the GROB file because the OS doesn’t know how to handle it.


Tip: If you have another software that you know opens GROB files, you can select it by hitting the "Show Apps" button.


Emu48 Requires Update

In some cases, you might have a newer (or older) version of a Graphic Object Bitmap File file that is unsupported by your installed application version. Installing the latest version of Emu48 from Christoph Gießelink is recommended. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.


Tip: Find clues on the correct software version by right-clicking your GROB file and clicking "Properties".


Summary: In either case, the majority of problems opening GROB files are related to not having the correct software application installed on your computer.


Other GROB File Issues

Assuming you have the right Emu48 version installed, other problems can prevent you from opening GROB files. If you are continuing to have errors with loading GROB files, other external issues might be to blame. Issues that aren't software-related:

  • GROB file type Registry entries are wrong
  • Unintentional removal of the description of the GROB file inside the Windows Registry
  • Corrupt install of Emu48 or other GROB-related program
  • Your GROB file is corrupted (issues with your Graphic Object Bitmap File file itself)
  • Your GROB is infected with malware
  • Device drivers of the hardware associated with your GROB file are corrupt or out-of-date
  • Your PC doesn’t have enough available resources to open the Graphic Object Bitmap File file
