Visual Basic Applications run very slow in AutoCAD 64bit

If you use VBA inside of 32bit AutoCAD you will have noticed that it is around 1000x times slower when running the same VBA code inside of 64bit AutoCAD.

This is because AutoCAD 64bit ships with the 32bit VBA DLL in a separate out-of-process executable rather than loading the VBA DLL inside of AutoCAD itself. Therefore, a lot of marshaling is incurred communicating between the out-of-process VBA executable and 64bit AutoCAD.

Other issues you may be seeing: Run-time error ‘429’: ActiveX component can’t create object

The Solution:

The best solution is to install 32bit AutoCAD on 64bit Windows, here are the affected versions along with their solution text…

Opening AutoCAD DWG file gives “Drawing File was created by an incompatible version” message

If you are trying to open a DWG file with AutoCAD and you get the message “Drawing File was created by an incompatible version” it’s because somewhere along the line your AutoCAD DWG files were saved with a newer version of AutoCAD.

All is not lost, you can make them open again in your version of AutoCAD, you just need to download the free DWGTrueView App from Autodesk – http://www.autodesk.com/products/dwg/viewers

Once installed, start DWGTrueview and open the DWG file in question, then save as making sure to select the lowest DWG file version that matches your version of AutoCAD.

Install 32bit AutoCAD 2017 on Windows 7, Windows 8 and Windows 10

NOTE: This blog post specifically solves issues related to these error messages on installation of 32bit AutoCAD 2017 on 64bit Windows…

  • “This operating system is not supported by AutoCAD®”
  • “You cannot install this product on the current operating system”
  • “You are attempting to use a 32-bit installer on a 64-bit operating system”
  • “This is a 32-bit AutoCAD® 2017. It cannot be installed on 64-bit Windows”

Installing 32bit AutoCAD 2017 on Windows 7, Windows 8, Windows 8.1 or Windows 10 64bit can be very easily defined in these short steps…

NOTE: These steps do not bypass normal Autodesk licensing/authorization, you should expect to use your own serial numbers in the normal way.

  1. Obtain your copy of the Longbow Converter here
  2. If you have CDs (if not check (3) below):
    1. Using Windows Explorer, copy Disk 1 of your AutoCAD 2017 install media to your hard drive, to a folder path c:\Autodesk\AutoCAD2017
    2. If you have more CD’s, copy them all directly over the top of Disk 1, overwrite all files in your previously copied c:\Autodesk\AutoCAD2017 folder
  3. If you have a single self extracting exe downloaded from Autodesk called something like AutoCAD_2017_English_Win_32_64bit_en-us_Setup.exe
    1. Simply run the exe, it will ask to unzip to a folder inside of c:\Autodesk, make a note of the folder for later use (we’ll refer to it from here as c:\Autodesk\AutoCAD2017), now click OK. Wait until all of the files have extracted, when they do, the AutoCAD 2017 setup will automatically launch – simply close it and move to the next step.
  4. Now, start the Longbow Converter tool, select the 1st tab, pick the c:\Autodesk\AutoCAD2017 folder, and click the Convert button.
  5. Once the conversion process is complete, click Install/Run Setup to start setup. Simply install as normal.
    1. Once installed, we recommend you disable the AutoCAD Communication Center/InfoCenter toolbar as it uses a lot of memory, causes slow startup and most people don’t use it anyway!
  6. Now you can happily run your AutoCAD 2017 32bit on Windows 7, Windows 8, Windows 8.1 and Windows 10!


– If your AutoCAD starts with a blank white screen…

  • Try turning down your screen resolution, if this doesn’t help…
    • from the Converter tool, pick the Tools->Clean Compatibility settings

– If you are unable to activate your product, or the activation process crashes:

– If you have crashing problems using the File->Open or File->Save dialogs inside of AutoCAD please read this blog entry on the File->Open or File->Save Crash in AutoCAD
