After the update from Windows 7 RC to RTM I noticed Daemon Tools was gone. I tried to reinstall it but it was impossible.
Daemon Tools relies on SPTD (a SCSI pass through driver) to do it’s magic and it checks whether it is installed. It seems that it couldn’t detect it on my system so it launched the SPTD setup, asked to restart the computer and then again and again.

I downloaded a new version of SPTD (1.60) from the product page but I had the same problem, SPTD installed, asked me to restart and then couldn’t detect the installed driver.

Googling I found out many others had the same problem and Finally I found a post in a forum explaining that it was a registry permissions problem.

I removed SPTD manually, re-installed and then re-installed Daemon Tools without a problem.

Here are the steps to re-install SPTD on Windows 7:

1.) Open regedit. And find HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sptd.
2.) Delete that folder "sptd" in the registry. If you can't, just right-click the folder, and click Permissions. Ask for "Full Control". Do this also to a sub-folder of "sptd" namely "cfg" (i actually already deleted it so i forgot). Just find ways to delete the "sptd" folder in the registry.
3.) Now rename or delete the 'sptd.sys' file found on Windows\system32\drivers.
4.) Download the newest SPTD Layer version "http://www.duplexsecure.com/en/downloads". Install and wait for confirmation to reboot.
5.) After reboot. Try opening the SPTD layer installer again and see if it tells you that SPTD layer is already installed. If it says so, continue on installing your Alcohol 120 or Daemon Tools.

 

UPDATE: If you get “failed to open service key”…

I just upgraded my desktop to RTM, this time to x64 version and I got this error while running the SPTD setup. After some tests and reboots I figured out how to make it work.

Open regedit and look for this key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_SPTD, try to delete it. If you can’t, try this: go folder by folder (0000 and control), open the permissions dialog, go to advanced, Owner and take ownership of the folder. Don’t try to apply the owner recursively, you have to set it on each individual folder. Then, in the security tab grant full control to “everyone” (again, folder by folder). Now you should be able to delete it. I also deleted the same entry in ControlSet001 and ControlSet002.
Finally, just in case, delete this entry too: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\eventlog\System\sptd

Now run SPTD setup again, you should be able to install it and after a reboot install Daemon Tools.

Bypassing the "failed to open service key" error is actually easies than further modifying the registry. It's enough to just run the installation with administrator rights. Worked perfectly for me. (MSDNAA Release version)

Thanks for the advice! I had to reboot before it would let me install (I kept getting the "failed to open service key" until I did).

Lewis: If you cannot delete a folder in the registry, you have to click on the owner tab and give your user name ownership.

For those that still get the error. In regedit select HKEY_LOCAL_MACHINE, then edit and FIND. Write sptd and wait for a result. It will probably give you a folder similar to the ones you already deleted. DELETE THIS TOO. Then search again and delete again until searching sptd gives back no result. Then restart pc and try to install SPTD 1.60 again.

Thank you!
This worked!

One note though:
for the UPDATED part, when trying to erase registry keys, you might get "Access Denied" or "Permission Denied" trying to take full rights for the key. In this case in Permissions window go to "Advanced->Owner" select/add yourself as an owner, check the first checkbox (you should have 2 below the owners) and Apply, then you should be able to gain full Rights and delete the key!

Thanks, this guide works perfectly. I finally able to get my daemon tools lite works again. Just to share, do restart you computer after deleting the registry and restart again after installing the sptd. If you are unable to delete the registry, do change the permission on each sub folder under each folder.

for those who couldn't change permissions you can also use psexec to launch regedit as the system user so you can delete the keys anyway.

http://technet.microsoft.com/en-us/sysinternals/bb897553.aspx

or search psexec on google it's the first link

in a command window (cmd.exe in start menu)
psexec.exe -s -i 1 regedit.exe

then delete the keys

for psexec to be able to work you have to have UAC off or run cmd.exe as an administrator (type cmd.exe in start menu, right click the cmd.exe search result and run as admin)

I have another problem, I do everything right. (But I don't have HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002 in the regedit, i have ControlSet001, ControlSet003 and ControlSet004. I just press ctrl+f and search for all the SPTD keys and deletes them all.) Anyway, when I restart my computer, it restarts itself over and over again. I can start in safe mode and in my latest safe settings. But then I have to install SPTD again and I still can't restart normally. But if I delete all the SPTD keys, I can start with no problems.

1.) Open regedit. And find HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sptd.
2.) Delete that folder "sptd" in the registry. If you can't, just right-click the folder, and click Permissions. Ask for "Full Control". Do this also to a sub-folder of "sptd" namely "cfg" (i actually already deleted it so i forgot). Just find ways to delete the "sptd" folder in the registry.
3.) Now rename or delete the 'sptd.sys' file found on Windows\system32\drivers.
If you go through steps 1-3 above and try to install a new version of SPTD then find you get “failed to open service key”… it's because you haven't restarted/rebooted yet. After steps 1-3 above you must restart for the changes to take effect. Restart and all will be as it should be.

Thanks to all the commented here. Unfortunately, none of the above worked for my W7 Ent install though. Out of frustration/curiosity, I installed the Pro trial instead of lite, and it worked right out of the box.

I spent almost two hours screwing with reg entries, rebooting, and nearly pulverizing my keyboard. I'm sure this will be fixed in the next update, so to all who don't want to go through this headache, just install pro and then look for a later release of Lite.

Same here. First the sptd problems, then the failed to open service key, then error code 14 from daemon tools!!!!

Downloaded Pro version of daemon tools, installed the trial version - first time, all ok!

The following steps worked on my pc:

1) Open cmd -> bcdedit /debug off

2) Open msconfig -> Boot -> Make all boot settings permanent -> Ok

3) Make tutorial step by step. Delete keys. Restart. Install daemon tools.

Without step 1) and 2) i got deactivate kerneldebugger error after start / reboot

Well, close, but no cigar. The instructions were good and everything seemed to work perfectly, until I tried to install SPTD. I don't get the "failed to open service key" error.

This is the error that I get:

SPTDinst-v176-x86.exe is not a valid Win32 Application.

I followed the link above and am sure I downloaded the right SPTD file. I'm using Windows 7 Ultimate - 32-bit.

What do I do now?

Any help would be appreciated.
