Understanding IRS Issues


Troubles Opening IRS Files

Missing Adobe Illustrator CC

Double-clicking your IRS file prompts the message "%%os%% Can't Open IRS File". If this is the case, it's usually due to the fact that you do not have Adobe Illustrator CC for %%os%% installed on your computer. 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 IRS-related program can be selected to open the file by clicking "Show Apps" and finding the application.


Adobe Illustrator CC Requires Update

Sometimes your installed version of Adobe Illustrator CC won't support your Adobe Save For Web Settings file. Download the latest Adobe Illustrator CC version from the Adobe Systems Incorporated 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 IRS file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).


Conclusion: The majority of IRS file opening issues are due to not having the correct Adobe Illustrator CC version installed.


Additional IRS Opening Issues

Even with the correct version of Adobe Illustrator CC installed, you can still experience difficulties opening IRSs. Other IRS opening errors can be created by other system problems inside of %%os%%. Additional factors include:

  • Invalid IRS file references in the Windows Registry (the "phonebook" of the Windows Operating System)
  • Deletion of the IRS file description from the Registry by mistake
  • Corrupt install of Adobe Illustrator CC or other IRS-related program
  • IRS file corruption
  • Your IRS has adversely impacted by malware
  • Hardware associated with IRS has outdated drivers
  • Your PC doesn’t have enough available resources to open the Adobe Save For Web Settings file
