After upgrading SOLIDWORKS or running a fresh installation you may notice that the field for Description in SOLIDWORKS Save and Save As dialog boxes has disappeared? This problem is caused by a library file called “sldpropertyhandler.dll” and to fix it you need to register this library file again.
How to fix the problem:
To fix this issue follow these steps:
1- Locate “sldpropertyhandler.dll” in windows explorer, it should be in your main SolidWorks installation folder. The default location is: C:\Program Files\SolidWorks Corp\SolidWorks
2- Right click on Command Prompt and run as administrator.
3- For Windows 7 type “regsvr32” and then drag and drop “sldpropertyhandler.dll” from windows explorer to Command Prompt. This will add the library location to the command line.
