I was not able to uninstall J32 using the instructions in the current J602 doc:
Windows
Delete the J program group by clicking Start|All Programs then right clicking
the J program group and selecting delete.
If you registered J as a COM server you can unregister it by running
....> [path to J install folder]\j.exe /unregserver
Running J with the unregserver option gave the error: Unregister not supported.
Using the unregister option resulted in the same error.
Running regsvr32 /u j.dll from the j32 bin directory said that
DllUnregisterServer in j.dll succeeded, but J32 j.dll was not removed from the
registry. The following 3 keys were present both before and after all attempts
to remove j32.
HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{21EB05EA-1AB3-11CF-A2AC-8FF70874C460}
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Wow6432Node\CLSID\{21EB05EA-1AB3-11CF-A2AC-8FF70874C460}
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes\CLSID\{21EB05EA-1AB3-11CF-A2AC-8FF70874C460}
If I manually rename j.dll in the j32 bin directory and rerun the test VBA
program, Excel reports that the specified module cannot be found.
Some doc from Microsoft (http://support.microsoft.com/kb/896459) says:
32-bit programs run in WOW64 mode and access keys and values that are stored in
the following registry sub key:
HKEY_LOCAL_MACHINE\Software\WOW6432node
and
To support the coexistence of 32-bit and 64-bit COM registration and program
states, the WOW64 subsystem presents 32-bit programs by using another view of
the registry. The WOW64 subsystem uses registry redirection to intercept
registry calls at the bit level. Registry redirection also makes sure that the
registry calls are directed to the correct branches in the registry.
So it appears that uses of DLLS from 32 bit apps on a 64 bit system will be
redirected to have access to only the 32 bit DLLS.
I'll take a look at Office 2010 later.
