[Resolved] Acronis DD 11 and Storagecraft Shadow Protect Desktop

I have Acronis DD Home 11.0 (2343) and Shadow Protect Desktop 4.15 (10129) on my Win7-64HP SP1 laptop running peacefully together. Now I want to update SPD 4.15 (10129) to 4.2.1 (15272).
However this installation stops immediately with a message that snapman from Acronis TrueImage (not DD?) has been found and that the installation has been cancelled. So I uninstalled DD, and used the ATIH2012 cleanup tool to get rid of the last traces of snapman etc.
I was now able to install SP 4.2.1. correctly.
However, when I try to reinstall Acronis DD. Halfway through the installation this message appears:
“The installation was interrupted before Acronis Disk Director 11 could be installed. You need to restart the installer to try again.”
and the operation is reversed. Trying again gives the same problem. Please advise.

DD uses the snapman driver too. Personally, I wouldn't try to have them both installed. Multiple snapshot drivers may not work correctly together.

Mudcrab,

Thanks for your comment. But does DD really need snapman? I am going to try to delete the snapman references in DD manually - I found the correct instructions. After all DD11.0 and SP 4.1.5 worked before without a problem when installed at the same time. It is possible that SP 4.2.1 is more "critical" than 4.1.5, which I am trying to find out from SP support.

THERE IS NO NEED TO UNINSTALL DD11 WHILE INSTALLING SHADOWPROTECT DESKTOP EDITION. JUST RENAME SNAPMAN.SYS AND INSTALLED SPD 4.2. AFTER INSTALLING SPD 4.2 AGAIN RENAME SNAPMAN.SYS TO ITS ORIGINAL NAME. I HAVE GOT BOTH WORKING AND COEXIST PEACEFULLY.

Thanks for the advice but it did not work for me.

Problem finally solved!!
None of the recommended actions worked for me. The following - actually quite simple - worked for me:
1. Delete all traces of DiskDirector 11 as follows: first uninstall the normal way, then with the Acronis TIH 2011 (NOT 2012 that causes other problems if you don't have TIH2012!!!) cleanuptool remove the final traces.
2. Install ShadowProtect 4.2.1, to be sure, uninstall (don't forget to deactivate first) the previous version first.
3. Install DD11.0 v.2121, which does not mind SP being there!
4. Run services.msc, look for ShadowProtect Service (there is only 1), open it, and stop it, leaving all else as is.
5. Now install DiskDirector 11.0 Update 2 2343.
6. Restart the computer.
This is what I did, it may be possible to skip step 3
