Failure to register backup_cpl_control.dll

Thread needs solution

Hi All,
I have updated my Acronis 2011 to the latest build and this dll failed to register. It is actually the exact same problem as when I first upgraded from 2010 to 2011. Except, I can't manually register the dll.
I have tried the following:
Uninstall, download and install.
Disable NIS 2010, disable UAC, uninstall, reinstall, repair install
Disable NIS 2010, disable UAC, run ccleaner, uninstall, reinstall, repair install
Disable NIS 2010, disable UAC, run ccleaner, uninstall, True Image removal utility, ccleaner, reinstall, repair install

The whole time, at each step, I have been trying to register dll manually using:
Regsvr32 C:\Program Files (x86)\Acronis\TrueImageHome\x64\backup_cpl_control.dll
from cmd with admin rights and
Regsvr32 C:\Program Files (x86)\Acronis\TrueImageHome\x64\backup_cpl_control.dll
using Windows Run and
From the dos prompt under admin privelleges changing to the C:\Program Files (x86)\Acronis\TrueImageHome\x64 folder and running regsvr32 backup_cpl_control.dll

Regsvr32 either says "C:\Program" failed to load or just does not say anything.
I have even tried to register the dll while the Acronis "Failed to Register" message Box is on screen.
I performed all installs with admin rights.

Feeling very frustrated right now because every time I look at the properties of a file, explorer crashes.
I have attached a zip of my system infromation and would greatly appreciate any help.

Hi, does anyone have the same issue?
I have even tried uninstalling and using the cleanup utility then creating a new Windows profile before installing and repair installing.
This dll does not register. I have tried both the 32 bit regsvr32 and the 64 bit regsvr32.
My file properties now have an acronis tab that crashes windows if you click on it. Is this only hapening to me or is it the software?

I don't have this problem, but your error "C:\Program" failed is due to a Quotation problem. You need quotes around your path because spaces are not allowed unless surrounded by quotes.

Use Regsvr32 "C:\Program Files (x86)\Acronis\TrueImageHome\x64\backup_cpl_control.dll"

Thanks Mustang. I gave it a go but it still does not register. Maybe I have done some harm to the registry with repeated attempts in different folders.
I paid for support last night using the Acronis Pay Per Incident system.
I explained the issue and they logged into my PC and saw the crashes when the acronis backup tab is accessed from a file's properties.
The guy said I need to talk to my PC manufacturer and contact microsoft about updating windows explorer. He did a demo backup and closed the call.

Summary
Me: - UAC is off, NIS is off, the dll fails to register and windows crashes when I access this acronis function
Him: - Acronis is working, contact the manufacturer, contact microsoft
Me: - The Acronis install said the dll failed to register and using these functions crashes windows
Him: - The backups are fine, acronis is working, I will close the call. OK?
Me: - But it crashes and failed to properly install.
Him: - Acronis is working you need to blah blah

I have followed Colin B's advice in another post and disabled acronis/windows integration in the help menu settings.
No integration and Acronis tabs means no more crashes. Support was a waste of money and time.

I don't believe it, Acronis service support just sent me an email with a survey for my service call.
They claim I paid for support and called because I "want to know how to activate ATIH2011"
What an outrage... I feel doubly ripped off. Apart from telling him about my issues, I told the gent I had just performed an install on a brand new windows profile and had not yet registered it...What the hell...
He probably made his quota on the basis of this lie.
