Word 97: How to convert Equation 2.0 into Equation 3.0?
Jodok Schaeffler
When I open a Winword 95 document with embedded equations
in Microsoft Equation 2.0 format with Microsoft Word 97, I cannot edit the
equations.
I get an error message "Word cannot edit the Microsoft Equation 2.0".
Equation 3.0 is installed. Did I miss something else?
Is there a converter Equation 2.0 to Equation 3.0?
Is it necessary to habe Equation 2.0 installed?
What can I do to edit my equations?
Any help appreciated.

This is a short note for users, or prospective users, of Microsoft's new
Office 97. Simply put - the new equation editor (ver. 3.0) does not work
correctly nor can you use earlier versions of the equation editor with MS
Word (according to MS tech).
No problem? Just uninstall 97 and go back to Office 95? Very non-trivial!
The 97 uninstall does not completely uninstall the product. Nearly two
hundred files must be manually removed according to a MS technical document
that is faxed to you. This document lists one file that, if removed, will
not allow any installations! Add to this modifications to the registry file
and you have a good amount of work ahead of you. If your MS Office 95 was
supplied with your computer but you purchased Office 97 separately, you
will not receive technical assistance with the re-install of Office 95. I
have already spent 2.5 days on this problem.
I have called the company that supplies the equation editor to Microsoft
and the problem with crashes upon installation and, once solved, problems
with overlapping mathematical symbols (not in all situations) has been
verified.
If you are interested in the details of the problem and the intricacies of
the uninstall procedure, I will post them on The Chemical Educator forum
this weekend.

I'm not sure how it got this way, but if you feel like hacking your registry,
I can tell you exactly what to add to make things work.
<WARNING: do not do this if you don't like playing with system settings!>
The registry has a neat little scheme for re-directing calls to one OLE Editor
so that they call the other one instead. Word's installer should have set
this up for you, but it sounds like this scheme isn't set up right on your
system. Try the following:
1. Open the registry editor by choosing File/Run, typing regedit, and
clicking OK.
2. Open the key called HKEY_CLASSES_ROOT, and scroll down to find
Equation.2. It'll be a long way down, below the file extensions and
right before Equation.3. If you don't find it, we'll have to create it.
3. Whether you create it or modify it, we need the tree under Equation.2
to look like the following (values are entered without quotes, but they
display with quotes):
Equation.2
|-CLSID value = "{00021700-0000-0000-C000-000000000046}"
|-NotInsertable value = ""
4. Now go back to the top of the registry, choose Edit/Find, type or paste
in {00021700-0000-0000-C000-000000000046},and click Find. The results
should be a the number you typed in surrounded by a bunch of other
similar numbers. If you don't find that, then you'll have to create this
subtree. It goes under the CLSID key under HKEY_CLASSES_ROOT. Whether
you create it yourself or fix it, it should contain the following (it
could contain more, but these are the minimums):
{00021700-0000-0000-C000-000000000046}
|-AutoConvertTo value = "{0002CE02-0000-0000-C000-000000000046}"
|-NotInsertable value = ""
|-ProgID value = "Equation.2"
Once these changes have been made, any program that tries to launch
Equation Editor 2 will get Equation Editor 3 instead.

Some equations can be opened with Editor 3, for some equations still
the same error message appears. I could not find out any pattern this
behavior follows.
One more thing:
In my case the error might have been caused by different languages for
the two versions of office: Office 95 in german, Office 97 in english.
The reason I come to this conclusion is the following registry entry:
{00021700-0000-0000-C000-000000000046}
|-AutoConvertTo value = "{0002CE02-0000-0000-C000-000000000046}"
|-NotInsertable value = ""
|-ProgID value = "Formel.2"
When I changed this to
|-ProgID value = "Equation.2"
it works, as I said. At least sometimes.
I got two more registry entries in HKEY_CLASSES_ROOT in addition
to the "Equation.2" and "Equation.3" entries:
"Equation"
and
"Equations"
Do I have to manipulate them to get the rest of the formulas into
Equation.3?
How comes that some equations are handled correctly and some
are not?

One problem is that this isn't what should be there.
HKEY_CLASSES_ROOT\Equation.2\
should only contain two keys: Insertable and CLSID. The rest of the
registration is done at
HKEY_CLASSES_ROOT\CLSID\<whatever number was listed in
HKEY_CLASSES_ROOT\Equation.2\CLSID>
Something is really messed up. Plus, Equation Editor 2 doesn't even come with
Word 97. Equation Editor 3 does, and it registers under EQUATION.3
My suggestion is that you:
a) Run the EQNEDT32.EXE program you have to make sure it is the right version
(version 3). If not, you will need to install the Equation Editor by
running the Word 97 installer, selecting Add/Remove, and adding the
Equation Editor. It may not have ever been installed, since it is not part
of the standard install - it must be done as a custom install item.
b) Once you are sure you have Equation Editor 3 on your system, quit any
running programs. Now start Word and see if it is listed in the
Insert/Object list. If so, you're done. Otherwise, quit Word and go on
to c.
c) Start a command prompt (DOS command line).
d) change to the directory containing EQNEDT32.EXE, and type:
EQNEDT32 -regserver
and hit Enter. Equation Editor will re-write its registry properly and
quit. This only works with Equation Editor 3.0.

I got a little different problem. My office 95 application can not find
equation 2.0 . Seems you people are quite familiar with those staff, could
somebody please help me out.
I have a Windows NT 4.0 ws(dual boot with windows95) with office 95
installed. I have the equation 2.0 installed. However it is not in the
object list. The equation editor EQNEDT32.EXE has been installed, and it
works by itself. I have tried to work with registry (regedit), the path
seems ok under
HKEY_CLASSES_ROOT\Equation.2\protocol\StdFileEditing\server
Thanks in advance
