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 should fail to create because it will use the 2.0 (resp 2.1) Version, it can't and didn't check for 2.2 Version. 2) Clean up the registry by

However the same code when run in Excel 2003 SP3 on Windows 7 32 gives Run Time Automation Error at line Set asc1 = CreateObject("System.Text.UTF8Encoding") I am unclear why it is failing in Excel 2003. Assuming it has something to do with dot net framework I re-installed dot Net 4.0 while 3.5.1 is already part of Windows 7 and Feature already enabled. There is very similar post on this site here but even it does not have a solution. What else should I troubleshoot further? Could this be something to do with missing or corrupt components / libraries or anything related? Thanks. Public Function SHA1(str1) Dim asc1 As Object Dim enc1 As Object Dim bytes, outstr, pos Set asc1 = CreateObject("System.Text.UTF8Encoding") Set enc1 = CreateObject("System.Security.Cryptography.SHA1CryptoServiceProvider") bytes = asc1.GetBytes_4(str1) bytes = enc1.ComputeHash_2((bytes)) outstr = "" For pos = 1 To LenB(bytes) outstr = outstr & LCase(Right("0" & Hex(AscB(MidB(bytes, pos, 1))), 2)) Next SHA1 = outstr Set asc1 = Nothing Set enc1 = Nothing End Function Private Sub CommandButton1_Click() Dim txt txt = TextBox1.Text TextBox2.Text = SHA1(txt) End Sub microsoft-excel vba runtime-error share|improve this question edited May 8 at 20:07 asked May 6 at 15:06 pat2015 725311 In the VBA Editor window, under Tools -> References, are any listed as missing on the machine/setup having the issue? –panhandel May 6 at 19:11 @panhandel - Thanks for your input. How do I know if something is missing? Default ones are tick marked plus I already added System, mscorlib & MSXML5 –pat2015 May 6 at 19:30 Any missing would be prefixed with "MISSING: " like the 6th one on this pic: cpearson.com/images/MissingRef.png –panhandel May 6
