It seems I've managed to cripple my Windows 7 Ultimate!

A few weeks ago I decided to do a clean install of a new (to me, anyway) version of Adobe Photoshop (I actually had two prior versions of Photoshop on my hard drive, so starting with the oldest one, I used "Revo Uninstaller" to remove them)

I've used "Revo" for years because after it uses a program's native uninstaller it seemed to do such a good job of scanning and deleting leftover registry entries and other program fragments that are scattered all over your hard drive. One can set the scanning level to either easy, moderate, or deep. This time I used the "deep" setting

The earlier version of Adobe Photoshop uninstalled without a hitch, but after removing the second version, the above-mentioned scanning procedure took an incredibly long time. I went ahead anyway and deleted all the entries it had found.

Then the troubles began…

I tried to open MSOffice Word, but I couldn't open any documents – I got the following error message:

An error has occurred in the script on this page
Line: 5
Character: 5
Error: Library not Registered
Code: 0
URL: res://C:\Windows\system32\mmcndmgr.dll/views.js

Screenshot:



Then I went to the Windows 7 "Add or Remove Programs" to see if I could "fix" Word and the "repair" option was not available. That's when I found out that "Windows Installer" was not working correctly.

Error message:

Problem with shortcut

The Windows installer service could not be accessed. This can occur if the Windows installer is not correctly installed. Contact your Support Personnel for Assistance



After that, I attempted to re install Microsoft Office and generated this:

Description:

Setup did not complete successfully. We are sorry for the inconvenience.

A search on the Microsoft website for "installer.exe" proved fruitless and their online “fix” didn't work either, so -- knowing I have numerous “Restore” points I decided to attempt a System Restore. That's when I found the next error, quoted below:

SYSTEM RESTORE:
System restore does not appear to be functioning correctly on this system

It seemed the only recourse was to restore one of my daily backups or even a recent System Image...but an attempt at that only got the last error quoted below:

BACK UP:
The backup application could not start due to an internal error.
Class not registered (0X80040154)

A volume shadow copy service component encountered an unexpected error. Check the application event log for more information. (0x80042302)

So that's where I am now – TOTALLY stranded (Also Known As: F****D!!) – I can't go forward, can't go back.
I'm writing this from the

Windows 8 Release Preview
Evaluation copy. Build 8400

Which I installed months ago in a separate partition on this same disk (actually I'm somewhat surprised that this “Windows 8 Trial” version is even still working

Any help would be VERY appreciated!!!
Thanks,

Revo uninstaller creates a restore point so you can back to a point before problems occur. Do that and uninstall the software normally afterwards. You still have the restore points, but they just don't work?

Do this http://www.sevenforums.com/tutorials/666-advanced-boot-options.html
There do "Repair you computer". Then "system restore"...that should work.

Thanks for all the suggestions!
I'll try them tomorrow and post back...fingers crossed!

Well, I'm feeling pretty stupid about not remembering that Revo UnInstaller makes a restore point before it uninstalls a program. I did "undo" the Photoshop uninstall, and that did solve a couple of problems (for instance, Microsoft Office now is working correctly). However, System Restore and Backup are still broken. Now I'm wondering exactly what the difference is between Revo's Restore Point (which works), and Windows Restore Point (which is still not functioning). I'm also wondering which of the 130,000+ registry entries that Revo originally deleted (but now has "put back") caused my cyber-breakdown.

Click to expand...

just boot from recovery environment an do a system restore to a date prior to running revo uninstaller!

System restore works isn't it? You can restore the revo restore point!

I have the same error message when i run services>standard then extended tab.
After registering mmcndmgr.dll the tab works fine,also i can start internet explorer and the tab works.
But if i start internet explorer first then go to services>standard,then extended tab,the error comes up
I'm still working on solving this problem,not toublsome but annoying

Greetings from MS Global MVP Summit in Seattle 2013.

I have stopped using Revo because of fatal problems it has caused due to its Registry key program not being as ingenious as CCleaner's.

Your best bet is to System Restore to a point before using Revo and then uninstall it using the Control Panel uninstaller which works perfectly fine.

Some of these are residual old habits from XP which aren't needed at all in an OS as perfect as Win7. It may need so little maintenance that we make trouble for ourselves using any old-school methods.

I still stand by the tools and methods suggested in the tutorials in my signature below since none of them have ever caused known issues. However even some of the harmless maintenance tools may not be needed based on five years now of working with the most perfectly balanced OS ever.
