I assume they have online support somewhere.

Then perhaps someone could instruct me where. But I've looked; I think not.

Maybe I put this badly. What I should say is this: I'm wondering whether anyone has experienced the problem of being unable to reinstall version 9 of DK after having installed and removed DK 10. I am inclinced to see my problem a symptom of the prior installation. (Not a bad installation. I used the Microsoft MVP Tool Microsoft Installer Cleanup to get rid of all effects of any bad installations, suspecting this might be the problem. It wasn't. I also tried uninstalling all of my other third party disk deframenters, in case that might be the source of interference.)

This may be quite relevant to the preceding thread. People talk of DK as "reliable," whatever that's supposed to mean. Well, one thing it surely does not mean is that it creates the kind of problem I'm experiencing. That it does so isn't proven. My experience might be happenstance and the result of some other system anomaly. But it is not a problem I often experience. And the interval between successfully installing DK 9 and then trying to re-install it was only a couple of weeks at most.

Also, reliable customer support is part of reliability of the product. I have always gotten excellent responses from Raxco customer support within a day or two. Here, dealing with a problem their software probably created, Executive Software doesn't respond in almost a week.

I have diskeeper 10 installed. I'm guessing that key is located at HKEY_CLASSES_ROOT\DfrgSnapin.DfrgSnapin.1\CLSID. You could try running regedit to see if that key exists or is accessible, and if not, manually create it.

I had checked that: it's what I meant when I said there was no problem with acces to the key. But I noticed something. When the install fails and I quit the installer, very briefly--almost subliminally--a notice flashes on the screen "Demo Shield Version 7.5." Something is trying to keep me from using what it 'thinks' is a demo. What I'm installing is not a demo version, but I am ineligible for further demo use of version 10, having already unistalled it and the 30 days or whatever having passed. This seems to me to further support that it is version 10 previous installation that is keeping version from getting installed. Perhaps Executive Software never dreamed that someone would unistall the version 10 demo and revert to version 9.

Demo Shield is just a installer-type menu system. I don't think it has anything to do with trial/demo of diskeeper.

What happens when you uninstall everything, then remove/rename that key, and then install dk 9?

Another option is to use regmon to see what's going on with that key.

First of all, let me start out by stating that I have utilized DK Pro version since 7 on my WinXP SP2 laptop (NTFS file system), but I did notice that from version 7 up to 9 Pro the overall resource usage had escalated greatly..

With DK9 Pro, it was averaging ~15-18k Mem usage (VM ~35k when defragging) and with this low-performace laptop that maxes out @320MB sdram w/Plll, it was putting a strain on my overall performance. Purchased a new 30GB Samsung Spinpoint 5400 RPM (3 wks ago) which helped, but I just tried DK10_Pro_Premier with I-FAAST (30-day Trail) and although it was better regarding its very heavy mem footprint, I chose not to upgrade for the $99...

When uninstalling DK10_Pro_Premier, it immediately b0rked up the WinXP (Diskeeper Lite-made by Executive software at the time, which of course is now Diskeeper Corp).........very disappointing as I had to do a WinXP Repair_Reinstall to rectify this... (btw, my laptop had just been formatted some 5 days prior to this so my WinXP SP2 files were clean)

Having sent a note to their Tech Support Div (which in the past, I received pretty prompt service) expressing disappointment in their 'Installers_Uninstallers'...as they advertise to the effect of: "If you ever want to revert back to the built-in defrag features of WinXP..........no problem"

Still haven't heard anything back yet, but have received about 25 of their ads to purchase DK 10......

Idiot why did you bring up a 1++ month old thread?!? God i hate people like that.

and if people start a new thread the other 50% of people get upset....

I'm not saying bringing up old threads is good, but everyone is always in 2 frames of mind. Either you make it and get told to search in a previous thread or you post in a previous thread and get criticised for doing that. *shrug*

Good we have such an informative thread on Defrag. But Funny enough no one mention MST Defarg.

It is small and light, don't use up as much resources as Diskeeper 10 and get the job done. Just wondering why no one is using it.

This thread is NOT an informative thread on defrag, rather one about Diskeeper. I can't believe you brought this thread back to life to ask why people don't use something else. :blink:
