IGS File Complications


Issues Opening IGS Files

SOLIDWORKS Removed

You encounter an error message such as "%%os%% Can't Open IGS Files" when trying to open your IGS. If this is the case, it's usually due to the fact that you do not have SOLIDWORKS for %%os%% installed on your computer. Your operating system cannot associate your IGS with SOLIDWORKS, so double-clicking the file won't work.


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


SOLIDWORKS is Out-of-Date

Sometimes your installed version of SOLIDWORKS won't support your Initial Graphics Exchange Specification Drawing File file. Download the latest SOLIDWORKS version from the Dassault Systèmes website to ensure you have the correct one installed. 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: Sometimes you can get a clue about the version of IGS file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).


Regardless, most of the IGS file opening problems relate to not having the right version of SOLIDWORKS installed.


Additional IGS Opening Issues

Although you might already have SOLIDWORKS or another IGS-associated software installed on your computer, you can still encounter problems opening Initial Graphics Exchange Specification Drawing File files. If you are still having problems opening IGS files, there may be other issues that are preventing you from opening these files. Other contributing causes:

  • File references in the Windows Registry for IGS are wrong
  • Corruption of the IGS file description inside the Registry
  • Invalid installation of a IGS-associated program (eg. SOLIDWORKS)
  • File corruption affecting your IGS file
  • IGS file integrity has been compromised by malware
  • Device drivers for IGS-related hardware are out-of-date
  • Windows cannot load your Initial Graphics Exchange Specification Drawing File file due to insufficient resources (eg. RAM)
