After installation, SOLIDWORKS automatically sets up file associations in the registry. However, these associations may get lost over time. Several symptoms indicate this has happened.
Perhaps the most problematic occurs when using Quick Search or the integrated search. The SOLIDWORKS file open or save dialog boxes can stop responding.
Here, we'll cover two methods for resolving the issue:
Start “regedit” as an administrator and open the key: “HKEY_CLASSES_ROOT”.
Go to each of the SOLIDWORKS file extensions, and check the “(Default)” value. To edit the value, double-click (Default).
They should be:
.sldasm – SldAssem.Document
.slddrw – SldDraw.Document
.sldprt – SldPart.Document
The screenshot below shows the settings for a SOLIDWORKS Part document.
Next, verify the information for each file type. This is still under the HKEY_CLASSES_ROOT section.
The values should be:
SldAssem.Document - SOLIDWORKS Assembly Document
SldDraw.Document - SOLIDWORKS Drawing Document
SldPart.Document - SOLIDWORKS Part Document
If the issue continues, move to Method 2.
Download the registry files here: SOLIDWORKS File associations reg files.zip
At this point, the SOLIDWORKS file associations will be restored.
If the file associations are good but the icons are incorrect, follow the steps below.
If the problem persists, you may need to do a complete uninstall/reinstall of SOLIDWORKS.
