Can No Longer Access Task Scheduler After Upgrading

[ritchie58]

I upgraded to the 2.0.1 version from the 1.7.0 version yesterday. Now I find I can no longer access Task Scheduler. The error says: MMC could not create the snap-in. The snap-in might not have been installed correctly. Name: Task Scheduler   CLSID: FX: {c7b8fb06-bfe1-4c2e-9217-7a69a95bbac4}   Is there a fix for this? Should I try to uninstall and reinstall? Already tried System Restore with no luck. OS: Windows 7 Ultimate 64 bit.  Regards, ritchie58...

The setup doesnt replace anything with the task scheduler. It just runs a command line to add the rule.
Something else is going on. So lets find out

I did a search and found a few things for you to try

After installing .net 3.5 framework, I went into Vista "Turn Windows Features On or Off" and unchecked all .net framework 3.0 features (eg Micrsoft XPS Viewer) ...  bad idea!!

I gather both the Vista Task Scheduler and Event Viewer needs .net 3.0 framework installed.

Solution: ensure the .net 3.0 framework (or one of the features under it) is "checked" in your Windows Features.

I know your on 7 but 7 is vista anyways, the same thing still applies 

Also found

In my case it was the files C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config and C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config which were corrupt. The tag <DbProviderFactories> had no end tag. Adding the end tag in both files fixed it. I suspect the installation of SQL Anywhere caused the error.

And this one (Try this one first)

After typing this I found a mmc.exe.config file that was forcing the version of .net.   Renaming the file fixed my problem.

You rock!  I spent a long time trying to figure this one out.  An application (Peachtree accounting) installed the .net 1.1 framework and hosed many of my MMC snap in's including event viewer, task scheduler and IIS 7 admin.

I looked in my system32 folder and sure enough there was an mmc.exe.config file that had the supported runtime section set to "v1.1.4322".  I couldn't seem to edit the file to comment out that section, vista wouldn't let me save it, but it did let me rename it to mmc.exe.config.BAK and sure enough everything started working again.  I'm guessing these problems with mmc and snap in's in Vista are all related to apps that install the .net 1.1 framework and windows vista's inability to protect that mmc.exe.config file.

One thing is for sure, seems to be .net related

Let me know how it goes and we will go from there.


Also during my search I came across this

It has a MMC repair you can try as well

Hi Richie  ,
Nice to find you here! I installed v.2.0.1 directly without starting with v.1.7.0! For me, the Task Scheduler is accesable & my CleanMem is there! Maybe I should not give advice about a software, that I do not know enough about myself yet, but if I were you, I should had uninstalled the software and installed v. 2.0.1 from scratch, if possible!
Cheers,
sweidre

Sweidre you get around don't you lol! Yeah I'm having trouble accessing Task Scheduler now. According to Task Manager the process is still running. I just can't access the U.I. for it. I tried to install the Windows repair tool that Shane left a link for but couldn't get it to install either. I'm not sure how to rename the file to see if that works. I normally create a system restore point before installing new or upgraded software but wouldn't you know it I forgot to do so before installing version 2.0.1. Since the process is still working I may have to live with not being able to access it. I know I could try to repair the system files with the OS install disk but that would be a last resort.

[Shane]

I will help you get it fixed.

But I promise it isn't the install of CleanMem that did it

Reason why I say that is these two commands are ran from the bat file to setup the task rule

%systemroot%\system32\schtasks /create /xml "Clean System Memory 64.xml" /tn "Clean System Memory"

%systemroot%\system32\schtasks /change /tn "Clean System Memory" /ru "System"

No files are installed that deal with the task manager or anything.

The setup is asking the task scheduler to create the task.

Lets try this first.
In your system32 dir look for mmc.exe.config
and rename it to mmc.exe.config.bak and then reboot.

I will try each thing with you to help get you fixed

I really appreciate your time spent helping me Shane! I found the MMC file in System32. Do I rename the file by clicking on properties?

[Shane]

Right click on it and choose rename

Shane

[ritchie58]

When trying to rename I got a message: File Access Denied  You require permission from TrustedInstaller to make changes to this file.

[Shane]

It should give you an ok or yes option, or does it just give you a close button?

What will make things easier is to turn the UAC off.

Go to the control panel.
Open user accounts
Click on Change User Account Control Settings
Slide the slider all the way to the bottom.
Save and reboot.

You will no longer get locked out of things such as renaming files and no more prompts asking for permission.
Honestly, the only the only thing the UAS does to my users is teach them to click ok on every box they see without reading it. System still get infected with the UAC on. So to me it is just annoying and nothing more.

You can always turn it back on if you wish

Once it is off and you reboot you should be able to rename the file.

Turned off UAC. Tried to rename and got the same message. I even ran the app as Administrator (no one else uses this PC so I am the Administrator) and tried to rename that way as well. At the bottom of the message box there are two options: Try Again and Cancel. Clicking on Try Again does nothing but bring up the same message box.

Hi Ritchie,
It seems, that Shane will magage in helping you, so follow his advice!
(My idea was to shutdown your computer, restart in Safe mode and try to uninstall CleanMem, but try to follow the help by Shane first now!)

OK give this a try

right-click properties, and gain ownership of the file.

properties-> security-> advanced-> owner.

after that set permissions to read and write the file if you need to.

Shane

[ritchie58]

I followed your instructions and was able to rename the file. I had to use the Full Control Permissions to accomplish this however. Now when I click on Task Scheduler I get the "Open With" dialog box. So my next question would be, which program do I use to open the application? We've got this far and I'm afraid of screwing things up so I'll wait for a response from you instead of experimenting to see which program works. I think we're almost there Shane!

[ritchie58]

Should I have it open with Windows Explorer? That seems like the logical program. Am I wrong?

[Shane]

hold the windows key and hit "R"
this will open the run command.

Put this in

%windir%\system32\taskschd.msc

See if that opens it

and the mmc.exe should be opening it.
