My life after DAS when theres a Win8 Crash ?

[dante]

Ok, new DAW up and running, only one fault. I can't run the DAS EQ that use the DASCOEFF11.SYS (MasterIT, Legend, C350L).

Issue:
1) Scope Run As admin : Adding MasterIT to project causes system reboot.
2) Scope NOT run as admin : Adding MasterIT to project the dreaded 'Cannot load DASCOEFF11 VxD' messages popup and EQ doesnt function.

Environmental / Test Factors:
1 ) ASUS Z87C running Scope PCI / Scope XITE-1D / Windows 8.1 x64.
2 ) User Access Control turned off.
3 ) Driver Signing off.
4 ) NoRebootWithLoggedOnUser registry key added.
5 ) XITE-1D patch applied.
6 ) XITE-1D cset.ini edit applied.
7 ) 64 bit DAS updates applied from both SC and DAS sites.
8 ) Checked ver number on DASCOEFF11.SYS is 1.0.0.1
9 ) Fresh and legacy installs tried.
10 ) Issue affects both Scope PCI and Scope XITE-1D projects.

Fallbacks:
These DAS plugs that use that itsy bitsy DASCOEFF11.SYS file have defined my sound for 4 years - now Im thinking about how to deal with life after DAS. None of the following options really appeal much:

1) Redeploy old system.
2) New (Supermicro) mobo.
3) Use different EQ.

Alternative suggestions welcome.

Install Windows 7 instead or run win8/scope at 32bit?

1) Scope Run As admin : Adding MasterIT to project causes system reboot.

Guess you get a BSOD? Can you see that .sys file mentioned in the BSOD?
Sounds like running Scope as Admin means you can indeed load the .sys, but that .sys attempts to do an illegal operation that violates protected process memory space, or who-knows-what...
While it won't help your situation, this utility is handy to interpret what's happened with a BSOD.

Unfortunately, more often than not, as an end user, you will only end up feeling like your achieving something by installing and running this - you won't necessarily get any direct benefit from its use, especially in this scenario when you know what .sys is in trouble....

You still got your dual-boot rig running?
For me, it's worthwhile sticking with Win7 32-bit, and to have a fully-playing Scope with minimal outlying annoyances...

Wonder if its the interplay between Win 8 and your motherboard chipset?
Anyone else experience this? Can't imagine the set of individuals who have DAS processors running on Win 8 being too great...?

1. Write to DAS.
2. There's lots of good EQs that I'm sure could replace what you have. Maybe you have developed a bit of a comfort blanket with them. Also maybe you should mix things up a bit anyway, rather than fall back on the knowns all the time. dNA, HPM Digital (Peter), standard EQs are all good.

I am going Windows 7 64-bit soon (not W8 ever) so compatibility is interesting to me, although I don't have any DAS plug-ins (except the packaged and free ones), so this particular problem won't affect me.

[dante]

. This is not a dual boot system - that dual boot system is now spared. I could setup dual boot as a test to isolate whether its a 64 bit issue or not though.

. If I run 32 bit I loose 12GM RAM which was for Kontakt and other VSTI.

. No BSOD - its a totally black screen and restart - takes about 10 - 15 seconds. Capturing some sort of logging was on my mind so might try sysinternals or blue_screen_view, and maybe run some sort of ram checker.

. Similar happened to JoPo w/ MasterIT but his is running now after installing the 64 bit DAS updates.

. Yes I'll write to DAS if nothing turns up here.

. dNa / SC / HPM would be the subsitutes but they don't have that MasterIT (or Legend for guitars crunch or C350L sparkle on vocals) sound

Also I thought of trying to update the C++ runtime thingy that Scope installs. Ill do that 2night.

do you need the 64bit dascoeff11.sys file? it's on the SC ftp site in the v5 plugins\64bit folder.

it's not a win8 problem.

[dante]

Tried that (point 7 initial post) - both from SC and DAS own FTP - its the same file - version 1.0.0.1 - and in the description it has comment about being the 64 bit version.

I know its not a Win8 specific prob because it works on my other Win8 system

[garyb]

then it's a file system problem.
there's no difference in the way win7 handles the DAS files to the way win8 handles the files.
if worst comes to worst, you can start over. the file in the 64bit folder is the only one you should need. as you've confirmed, it works in your other win8 system.

now the stupid, obvious question. you ARE running Scope "as administrator"(right click on the Scope icon, choose "run as administrator", answer "yes" when the warning window opens), right?

[dante]

Tried both.

If I run as admin, the box crashes on device load.

If I dont run as admin, the popup warning messages come and the device loads but theres no EQ functionality. Only the input gain controls work.

Ive done a fresh Scope install (direct from the XITE CD) - no difference from first install (downloaded from FTP).

Yes something do do with filesystem seems most likely.

[jksuperstar]

Its possible the sys you have is corrupt, so try check md5 signatures of the two files you have to compare them. Its a long shot, I know. Do you have other 64bit .sys extensions to scope in use running OK?

[dante]

I've tried a few diff copies of the .sys - the one I had on old system, one from SC FTP, one from DAS FTP and one from the XITE CD.

They are all the same size and version so corruption unlikely.

Ive got the file in 2 different Scope installations (PCI and XITE) and both fail.

A couple of Bowen synths run ok, not sure what other devices use .sys, but I can check.

EDIT: I get the same on trying to load an STS

[garyb]

it's not sys files in general that is making the trouble!
it's nothing to do with win8.

it's your system.

have you done any customization or extreme tweaking of the os? turned off services? turned on data execution prevention(DEP)?

[dante]

Not much. Visual Effects turned off, power saving turned off, DEP is set to 'Turn On DEP for Essential Windows and Programs Only' - I cant see any option to turn it off altogether.

EDIT: I just ran an bcdedit command to turn DEP off & rebooted. - no effect

Does it matter if the certificate has expired ?

DAS cert

certificate? no, microsoft was never paid to approve the file. it's not necessary or related.

are you sure that you're really running in administrator mode?

it's still early. starting from scratch might be easier. you've run these plugins on another computer running win8 right?

where did you get the rest of the DAS files from(the dev file, etc)? if you took them from an old installation, maybe re-downloading them from the v5 plugins ftp folder would help.

[dante]

There are 2 ways of running as admin - a shortcut property checkbox and right click run as admin. Ive tried both - numerous times.

The MasterIT files all come with the x64 update from SC site and DAS site.

One lot I got from a DAS link from JoPo that he used to fix the same problem. I also tried the files from the old system. There was the sys file, the dev, the pre, the dll and maybe one other.

Also get same error trying to load any STS, which I wasn't getting on old system.

I think it's like you said - nothing to do with the files, something in my system.

Rebuilding Win8 from scratch is an option, but I'll probably check with DAS as next step before doing that anyway.

Win8 was installed by vendor.

They put in a dual head graphics card with a big bloody fan that obscured one of the PCI slots so I swapped it with the thinner Nvidia in the old system. Ill take it out as a test to elinminate any conflict there. Plus check the IRQs again.

Last night I deleted the Visual C++ Redistributable and reinstalled it - no joy there either.

EDIT : I just found the following post from Fidox : http://forums.planetz.com/viewtopic.php?f=1&t=32720

Like I suspected and already have some issues with this new update for Windows 8.1 64bit. I un-installed spring update for Windows 8.1 (KB2919355) and re-installed Scope drivers again and everything works just great now ! No freezes or blue screen !

DAS C350 and MasterIT EQ !

So looks like a re-install of Win8.1 from the CD the vendor supplied is the next step. Hopefully that CD is pre Sping Update fidox mentioned (April 2014) http://support.microsoft.com/kb/2919355 contains security updates so likely affecting filesystem access you could be on the money there GB.

Ill check with Vendor that they installed from CD then applied the spring update. If so, we have a hot suspect. If the CD contains the update, I'll demand a base Win8.1 CD.

[w_ellis]

I don't know if you'd need to re-install to do what fidox suggested. I think you just go to "Installed Updates", find the KB number he mentioned and right-click Uninstall.

[Eanna]

Just spotted on:
http://support.microsoft.com/kb/2919355

Important All future security and nonsecurity updates for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 require this update to be installed. We recommend that you install this update on your Windows RT 8.1, Windows 8.1, or Windows Server 2012 R2-based computer in order to receive continued future updates.

It's a new system incompatibility that Microsoft introduced with that Update, so your problems should be communicated to Microsoft. But the software that is no longer compatible is Scope, which hasn't gone thru Microsoft certification. So you'd imagine that it'd be back on the developer (DAS in this case) to involve themselves in the fix.

[garyb]

perhaps they soon will, but why aren't more people running win8.1 having this issue?
there may be some circumstance required before the problem shows itself.
do you browse the internet on that computer? if not, you probably will not need an update for a looong time. uninstalling the update might be a quick, easy cure in that case. it's possible that m$ just messed up this update and another that fixes what this update broke will be available shortly(assuming m$ knows that there's a problem).

[Eanna]

True for ya

[dante]

perhaps they soon will, but why aren't more people running win8.1 having this issue?.

Maybe they are, or maybe they have turned updates off so never got the April ones,or maybe they don't use MasterIT or Legend, or maybe only certain mobos are affected. C350L works, where C350 didn't, same as Fidox. So whatever DAS did there could possibly be done to MasterIT and Legend, so we get a MasterITL and a LegendL.

Anyway I removed security updates and it didn't work now I'm doing a reinstall.

It says build date May 2014 on the CD so maybe the April updates are part of the OS now on the CD.

So if the issue is still there, I will probably try the Win8 Pro CD that I used to install the old system last year. In that case I'll probably have to buy another license.

The saga continues.....
