cannot install Acronic TrueImage 2010 in Wndows 7

If it installed okay in Vista 64 bit, it should do the same in Win 7. Try r-clicking on the exe file and choose "Run As Administrator" even if your login status is Admin.

I did the "Run as Administrator" thing already. Still not working

Your system probably needs some "house cleaning" using software like CCleaner. Or you have something running at startup that is interfering with the installation - click the Start Orb and type msconfig. In the Startup tab look for items that you can disable temporarily without affecting the startup of the system, reboot and try the TI installation again. If you are running any Norton programs, those would be the first I would disable.
Another thing to try would be to disable User Access Control temporarily.

I've done all that (CClean, run as admin, wiping out any previous instances of Acronis), still no joy. I am get very quickly disillusioned with Acronis and will be wanting my money back, but I'll give it one more chance. Any further ideas? Please see attached jpg for latest (repeated) problem

Wow ... that's a weird situation ... maybe someone else can jump in here and offer a suggestion.

Hi David,
I don't have a solution to your problem, or mine.
I get the same error message you do when trying to install ATI on a dual quad machine. I have edited the registry of all previous installs, and still no luck. (First I ran Windows Install Cleanup from MSoft, but so many ATI registry entries esisted afterwards, I manually deleted them.)
Since ATI 2010 did not install on my first machine, I tried it on an older Pentium D. No problem, it installed and worked properly! Both systems are running win 7.

I have given up on Acronis - it is more complex than it needs to be for what should be the simple jobs of backing up an image (Easeus Todo is now my preferred tool for that) and of backing up data regularly (Karen's replicator is now my preferred tool for that). I've reinstalled Windows but I'm simply not going to waste any more time on Acronis - especially since the only time I really needed it it failed to work. Farewell Acronis!
I should mention that the only reason that I bought the upgrade to ATI 2010 was because I believed their claim that it works on Win 7 - clearly this is often not the case. I hope they send me a refund for the unnecessary and wasted upgrade (I'm awaiting their reply).

First W7 has two versions of 'Admin', there is an account that has Admin permissions, which is the one available when W7 is first installed and then there is a 'proper' Admin account which is disabled by default.

I would think there are one of three problems here.

Either there is a program that is stopping the installation, now although that idea has already been tried, it is possible that some firewalls and A/V programs aren't fully disabled when you think they are. The only way to be sure is to boot into SAFE mode and disable all F/W and A/V services plus the entries in MSconfig. Even then there are some programs that have embedded themselves with the system so tightly that only running a sysinternals program will reveal it. I doubt though that such a program is causing this problem.

I would also check other utilities if this is a brand name machine and their 101 gizmos have been re-installed.

I suspect more likely that for some strange reason TI is unable to access the registry. This theory can be tested by opening registry in regedt32 (not regedit), selecting HKEY_Local_machine and then drilling down until current_control_set, and then just see if you can open registry keys without getting a permission denied message.

The third alternative is that the download is corrupted somehow and perhaps another 3 hours waiting for the slow Acronis Server to download the installer is in order.

It obviously is installable on W7, the question of course is, why not on yours!

This computer isn't on a network by any chance or is using an SOE version of W7?

Check your W7 Group Policies to make sure something strange hasn't happened here and something has been enabled.

Many thanks for your suggestions Colin. :-)
However, since I am now working on a cleanly reinstalled Win 7 (as of two days ago) and using Easeus Todo and Karen's replicator without the kerfuffle that Acronis requires, I don't intend to start fiddling around further with Acronis. Acronis requires such complications that it has been shelved in my downloads folder and probably won't be installed my new set up.

(I would add that my faith in Acronis had been badly dented 8 months ago when I really needed it and it didn't accept the backup image file that it had created, despite that fact that the image file had been verified - I had been hoping for better things with TI 2010, which was why I bought the upgrade (deemed Win7-ready), but, to be honest, my faith in it is now shattered.
On the other hand my faith in Easeus is much sunnier - before I clean-reinstalled Win 7, I checked an Easeus backup file and successfully recreated the Easeus image with no problems at all. I didn't actually need that particular backup since I was going to reinstall anyway, but it was nice to know I would be able to trust Easeus for the future).

Acronis have simply complexified themselves into such a situation that a large number of their customers have given up on them; I'm sure I am one of very many dissatisfied customers. If Easeus can do its work simply and without Acronis's kerfuffle of going into the registry merely in order to install it and such like, then Easeus is the way I'll go.

It is most kind of you to offer these explanations, Colin, and I shall take due note of them should I need to do such things in the future, but, for now, Acronis is history on my system and likely to remain so.
Kind regards
David
