@tmodel46 & Mike - the error seems very much like the one documented in the following thread which also has customer generated workarounds for it.
If you are trying to run SSR 2013 R2 (and probably SSR 2013) under Windows 10 then there is a workaround to fix the licensing issue which is documented in the thread in this same forum called
"Windows 10? New software update for Symantec System Recovery 2013 Desktop Edition?"
A bit of the way down Page 1 there is a message by CJM that fixes the problem with SSR 2013 R2 by changing the Compatibility mode of the key executable that determines whether you are running under a supported operating system or not. This fix is likely to also work with SSR 2013 - since you were running ok under Windows 8.1 previously and and is likely to also then reactivate your license automatically. (mine did).
Similarly on Page 2 of that same thread near the end there is a simple fix documented ( by weff ) that tackles 2 other problems with running under Windows 10 This is also likely to work with SSR 2013 version
1. the SRD Wizard won't run (fix = change compatibility mode to Windows 8.1) on SRD creator executable
2. Some PC's may have issues in that Typical mode SRD creation will not work. It will fail with an error like ECA3232B: and ECA3232C: - the solution at present is to run in Advanced mode.
3. In addition, under Windows 10 where you have to run SRD Creator Wizard in Advanced mode then it is likely that the iso it creates will not boot fully as it fails with an error with a missing dll - oledlg.dll. There is a simple fix also documented in the patch.
I won't repeat the text inline for either patch - please refer to the other thread -
Page 1 .. CJM documented fix
Page 2 weff documented simple fix. - This is towards the end of page 2 and not the start of page 2 which was a fix but it was complicated to apply and needed to be done after each SRD iso was created. The simple fix at the end of page 2 is done just once and then you shouldn't need to apply again.
Since this work was done with SSR 2013 R2.SP3 version I do not know what differences there will be with the SSR 2013 version properly running under Windows 10. As you have found - to get support for SSR 2013 R2 you need to have a valid support contract - so if yours has expired you will only be able to run with SSR 2013 - but make it think that you are still running under Windows 8.1
Please give that a try as both fixes are really easy to apply and are likely to fix your problems. (I think someone has already done so and it ran ok - but that is also in that Windows 10 thread.
I have found that the later version works fine - but both versions now detect the Operating System version and disable the license and SRD Disk Creator Wizard under Windows 10.
There are also caveats to this fix - Do at your own risk - but I have tested this to the extent of a full Windows 10 restore from an image created under Windows 10 and written back using a newly created SRD boot disk. The creates and restores have been fine - but there has been a report of someone having issues trying to restore an encrypted file - but nothing beyond that. PC's with vanilla systems and not relying on special Windows 10 only features should be ok... but also no guarantees.
