I'm having some issues with encryption in Microsoft Office documents. When I try to create an encrypted file, I get:
When I try to open an encrypted file, I get:
I had some deja vu back to the time I hacked up Windows 2000 so Office 2007 would run on it, with the extended kernel and some DLL patches from Windows XP. In the end, Office 2007 worked, except it couldn't save encrypted documents - it could open them, though.
This has me puzzled, because this is an official supported configuration and I can neither save, nor open on a newer version of Office on a newer version of Windows.
This is the latest version of Windows XP SP3, patched through 2019, and the latest version of Word 2010 patched through July 2020. I have Office SP2 version 7214 (October 2018) and Word version 7254 (July 2020). Only difference is since 2018, updates have broken Office 2010 on XP SP3, so I have the MSO.DLL file from KB4092483 (which dates to Sept. 2018) - without it, Word fails to start at all, because MSO.DLL references an > XP only function in the DLL file.
No other issues, just this one - somehow, encryption does not seem to be working at all. Is there such a thing as a High Encryption Pack I can install? I've looked and I can't find one anywhere from Microsof.
regsvr32 C:\Windows\system32\schannel.dll regsvr32 C:\Windows\system32\crypt32.dll regsvr32 C:\Windows\system32\dssenh.dll regsvr32 C:\Windows\system32\rsaenh.dll
With the first two, I get "..the DLLRegisterServer entry point could not be found." error - the other two are good.
