Daemon Tools lite on Windows 7 x64 and the SPTD 1.51 problem

Published Monday, September 07, 2009 4:30 PM

Today I just had to solve a problem I have had for a while. When upgrading to Windows 7, I installed Daemon tools lite and everything was working fine. That is until last week or so when I started to get this strange error: This program requires at least Windows 2000 with SPTD 1.51 or higher. Kernel debugger must be deactivated. (Text in picture in Swedish).

The error text in Swedish

It seemed that I was not the only one having this problem. A quick search on Google and the Daemon Tools forums revealed a barrage of bad language and people using the word “plz” a lot. This daemon tools forum post, is a good example. There were a lot of solutions but no one that worked on my box. Apparently Microsoft issued a patch that has wreaked havoc for many users, including me. One solution from Daemon tools was to uninstall this patch.

Since I am not a fan of uninstalling patches I tried other solutions and I found one that works for me: Turn off “DeepGuard” in F-Secure. Do not turn it off all together(!), just during Daemon tools start-up. Allow Daemon to start and then you can turn it on again. Also note that I had to do this even though the program is marked as safe in F-Secure.

This is not a permanent solution and you cannot use the auto start option in Daemon tools, personally I never did anyway.

It is the stangest thing! Once I disabled F-secure DeepGuard and started Daemon tools, everything is working well, even with DeepGuard turned on. The auto-start option even works.

[Edit 09-11-01]
A commenter named Allan solved the problem by turning off the Windows Firewall. Now this is something I would not recommend, however I might work like it did for me and F-secure. Turn off the firewall, start Daemon, turn on the firewall.

[Edit 09-11-10]
My Dameon Tools installation told me a couple of days ago that there was a new version available. This has full Windows 7 support and uses version 1.62 of SPTD. So, the troubles might be over. Get it at: http://www.disk-tools.com/download/daemon

[Edit 09-12-14]
Since people seem to still have some issues I must ask you to verify that you are using the same version as I, since after installing that I do not have any issues about the product. I am using DAEMON Tools Lite v4.35.5 (with SPTD 1.62), which is the version you get if you download from here. Also note that the good people at Daemon Tools have a forum.

Maikk posted a very useful comment: "for those still asking for help and are using vista/7 try running cmd and type bcdedit /debug off, Vista has a kernel debugger enabled by default, and this needs to be disabled.  forum.daemon-tools.cc/.../kernel-debugger-please-help-19048"

I just installed Windows 7 upgrade for my Vista 64bit Home Premium and when I tried to run or uninstall Daemon Tools Lite it would pop up this message. I was able to fix the problem by turning off the Windows Firewall under Control Panel, System and Security. After I uninstalled the old version on DTL I found the new version that is compatible with Windows 7 (Look on Demon Tools web page or Google) and that fixed the problem. Now when I run the new version no message and everything seems to work just fine.

Hope this helps some of you

Allan, Is it true? I also upgraded my os to win7 from vista 64 bit home premium. And, Install the new daemon. But it did not work. Hehe, really compatible with win7? I suspect.

EDIT
I looked at Daemon tools home page (http://www.disk-tools.com/download/daemon) and it said "Full Windows 7 Support".

You need to conact me via the blog if you need specific answers. This is not a forum. However, there are some helpful tips in the comments section. Read them and then e-mail me.

Run the install in Windows XP Sp2 compatibility mode. That solved it for me.

[That's a good idea. I just installed the new version (using SPTD 1.52) on a new Win 7 machine and it works just fine. Try downloading the new version.]

hmm im having this problem and i just downloaded a fresh version from the site and still have the window.... guess ill resort to the firewal thing

That's strage I gotta say. After installing the latest version of daemon I have ha no such problems at all...

# Tim said on Friday, December 11, 2009 6:55 PM

I'm having the same problem as Jordie.  I have full version Win7 and am attempting to download the new (full Win7 support) version of D-Tools. I get the same message of "This program requires at least Windows 2000 with SPTD 1.51 or higher. Kernel debugger must be deactivated."

Life is a ***.

I am having the same problem with Dlite 4.35.5, everything was working fine until I updated Zone Alarm, now its showing the above mentoined message. But if I disable ZoneAlarm and Forcefield, its working normally

# Mohit said on Saturday, March 06, 2010 10:10 AM

It's showing me the same error, only it says version 1.60 for SPTD. I have tried to reinstall Daemon tools many time without success.

 Have you tried to temporary disable your fw/antivir?

# maikk said on Sunday, March 14, 2010 4:18 AM

hi dudes

for those still asking for help and are using vista/7 try running cmd and type

bcdedit /debug off

"Vista has a kernel debugger enabled by default, and this needs to be disabled."

forum.daemon-tools.cc/.../kernel-debugger-please-help-19048

worked for me

Good point. I will update the post.

# War Machine said on Saturday, July 10, 2010 9:37 PM

None of that works. Turned off firewalls. And there is no SPDT.

# henry said on Monday, July 26, 2010 5:50 PM

it's actually just a little trick. press windows&r, input msconfig, go to boot option, advanced options, untick the "debug" then reboot, everything should be fine then.
