Excel Automation Error The Object Invoked Has Disconnected
due to Office Service Pack 3.0 caused by Forms up vote 6 down vote favorite 4 After installing all latest windows updates my Excel VBA code is showing an automation error at the very start of the first module. It contains some forms as well as numerous modules of VBA code. However, when removing the forms (and associated code) everything is fine. The same excel automation error unspecified error thing happened about a year ago after some other windows updates. Back then deleting the .exd files did the trick, but the current updates (including Service Pack 3) seem to be different. What is going on and how can I get the forms to work? All the code is unchanged and has survived all previous windows/office updates. Running Windows 7 (same happening on Vista machine) and Office 2007. windows excel vba ms-office windows-update share|improve this question asked Aug 15 '12 at 14:38 Rob 4343716 add a comment| 11 Answers 11 active oldest votes up vote 16 down vote accepted I used to see this a lot with Visual Basic and Crystal Reports; either due to a bad deployment or DLL Hell. So, my guess is that it's not the code but perhaps some 3rd party controls (OCXs, DLLs) you're using. Check your References (In VBA IDE, click Tools and References) and to see where each DLL is pointing. See if any of the dates on the libraries are different than a working machine and you may find the culprit. Edit The OP found the problem by following the steps above. The fi

This made the workbook "loose" reference to MSCOMCTL.OCX (quote marks on "loose", because the reference is still ticked but no longer works, the workbook doesn't compile because of "Compile error: Object library feature not supported" or "Automation error") It seems that the update modifies the registry key HKEY_CLASSES_ROOT\TypeLib{831FDD16-0C5C-11D2-A9FC-000F8754DA1}\ by adding a SubKey 2.0, but leaves it empty, and doesn't register the new MSCOMCTL.OCX. Fixing the problem requires 3 steps: 1) MSCOMCTL.OCX. needs to be un-registered and re-registered (Start button/search/command/right click command prompt/run as admistirator: c:\Windows\system32>Regsvr32 /u C:\Windows\SysWOW64\MSCOMCTL.OCX c:\Windows\system32>Regsvr32 C:\Windows\SysWOW64\MSCOMCTL.OCX When registering the new MSCOMCTL.OCX (Version 6.1.98.46) via REGSVR32, a new key is added in the Registry: HKEY_CLASSES_ROOT\TypeLib{831FDD16-0C5C-11D2-A9FC-000F8754DA1}\2.2 If there was a SubKey named 2.1 already existing, it enters a reference that 2.2 is now the Key for use. But it doesn't do anything to the empty 2.0 SubKey ! If there is a 2.0 (or 2.1 for that matter) SubKey with nothing in it, any object using that OCX shou

Previous Next News Excel automation error after Windows update TAGS: Excel - Technical DATE: Mon 20 Aug 2012 BY: Stephen Aldridge Share Excel automation error after Windows update Recently some of you may have found automation error that, after installing Windows updates that were issued on Patch Tuesday in August 2012, Excel would throw a non-specific ‘Automation Error' when you tried fire it up. Hmm, not great when you're trying to get some work done. From our testing, this seems to happen with the 32-bit versions of Excel 2007 and 2010 (and possibly earlier versions too) where an add-in is loaded on startup excel automation error (be it a 3rd party add-in or your Personal.xlsm) that has controls from the Windows Common Control library (mscomctl.ocx - things like the TreeView, ProgressBar and Slider controls.) Fortunately, there seems to be a simple fix to this as follows: 1. Close Excel. 2. Open a command prompt with elevated privileges (i.e. right-click cmd.exe and choose ‘Run as Administrator'). 3. Type the following at the prompt depending on which version of Windows you're running: a. For 32-bit Windows: regsvr32 "C:WindowsSystem32MSCOMCTL.OCX" b. For 64-bit Windows: regsvr32 "C:WindowsSysWOW64MSCOMCTL.OCX" This action simply re-registers the mscomctl.ocx library on your system. After doing this you should find that Excel starts behaving again. If not, then we also found that performing a ‘Repair' of Excel using your original MS Office installation media also worked.
