VBA and SOLIDWORKS x64

SOLIDWORKS 2013 SP0, and later, include a new version of Microsoft Visual Basic for Applications (VBA 7), which supports both 32-bit and 64-bit systems.
 

• Declare statements in VBA macros and applications created before the SOLIDWORKS 2013 release will not compile in VBA 7 on 64-bit systems. You must mark Declare statements as safe by using the PtrSafe attribute in your VBA macros and applications on 64-bit systems.
  
  Use the LongPtr variable type instead of the Long or LongLong variable types for function arguments representing pointers if your VBA macro or application must work with both 32-bit and 64-bit SOLIDWORKS.
  
  The LongPtr variable type and the PtrSafe attribute allow you to use the same Declare statement on either 32-bit or 64-bit systems.
   

• 32-bit ActiveX controls used by VBA macros with SOLIDWORKS 2012 and earlier:
   
  • must be recompiled on a 64-bit system.
     
  • will continue to work on a 32-bit system.

For more information about VBA 7, see Microsoft's:

• Compatibility Between the 32-bit and 64-bit Versions of Office 2010
