Hello kaczor954 and all the Code 52 tormented people,
Windows 7 64Bit got a refresh with it's Driver Signing behavior some time ago (03/2016).
Microsoft dropped the support for their SHA-1 code signatures and moved
to the SHA-2 signature standard. The later Windows 8 and 10 already support
the SHA-2 standard out of the box.
The RME drivers v4.1.4 and before were SHA-1, so you could install these on a fresh Win7-64
and work, but to use RME HDSP drivers till v4.1.4 ( v4.1.5, v4.1.7 ... ) you are
forced to update your system ONLY with :
KB3033929
This is the Windows 7 64Bit SHA-2 code signing support Update.
For RME it's simple to make one driver for all ( W7, W8, W10 ), but if you have a
offline Workstation like me and many other users, you are forced to do this update.
Seperate Drivers are the solution : SHA-1 signed ones for W7 only,
because they work out of the box ( no CODE 52 ) and the SHA-2 model ones for W8 to W10.
But we won't get this ( i hear someone saying : time to get W10, the same who
said it's impossible to build a 64bit driver for the loved Hammerfall 9652 series, which
died for all 64 Bit users some years ago and we were forced to update to a HDSP ...... )
I think the driver golden times are gone.
Check the actual v4.1.7 driver details -> hdsp_64.sys. Look at the copyright owner Info.
See the signing crap ?
