Well, the encryption software does install on 64-bit systems, its the WinPE they provide which does not have 64-bit drivers to facilitate the bypassing of encryption within WinPE. That environment contains some tools for importing an encrypted MBR as well as bypassing encryption in order to interact with an encrypted offline OS. That part works, because the WinPE is 32 bit. However, their 32 bit drivers do not work inside a 64 bit WInPE, which is needed to successfully run MSDART tools on a 64 bit offline OS inside WinPE.
We will be moving to Bitlocker eventually, but 8,000+ PCs will still have our old encryption (Sophos), which if previous experience is any indication (we went from Pointsec to Sophos, and it was 3 years+ before old assets disappeared through attrition) we will be supporting it for quite some time to come.
I suspect what i want to do isn't possible, but i just wanted to be sure i'm not missing something. I guess if i knew the dependenices that bootrec had, i could export the right files from the 64 bit MSDART but that might be a bit far-fetched, or just take tons of trial and error.
Something else that might be helpful to know,,, can anyone recommend a standalone password changer? One that doesn't need to be booted from? I know there are linux based tools but they seem to require that you boot into the linux shell from an iso and then interact with the offline OS, which won't work on an encrypted hard drive obviously.
