RQ File Complications


Issues Opening RQ Files

D2RQ Platform Removed

If you attempt to load your RQ file, you experience a message such as "Can't Open RQ Files". When this happens, it is commonly due to D2RQ Platform missing in %%os%%. The OS won't know what to do with your RQ file, so double-clicking to load the file doesn't work.


Tip: If you don't have D2RQ Platform installed, and you know of another program to open your RQ file, you can try opening it by selecting from the programs listed under "Show Apps".


D2RQ Platform Requires Update

Your SPARQL Query file is incompatible with D2RQ Platform because you might have the wrong version installed. Download the latest D2RQ Platform version from the Open Source website to ensure you have the correct one installed. This problem is predominately due to having a SPARQL Query file version that was created by a newer version of D2RQ Platform than what you have installed on your PC.


Tip: If you right-click on your RQ file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.


Summary: Not having the right D2RQ Platform version on your computer can cause problems opening RQ files.
