Windows 7 support has ended

Get Windows 10 to continue receiving support.

Upgrade now

"The windows installer service could not be accessed. this can occur if the windows installer is not correctly installed. contact your support personel for assistance" Fault module - msvcrt.dll

Can anyone verify either of these resolutions? I have almost the same issue but I'm trying to run the "Detect and Repair" function in MS Office Picture Manager 2010. This is the entire error I receive: "The windows installer service could not be accessed. this can occur if the windows installer is not correctly installed. contact your support personel for assistance."

Here is the event log:

I'd really like to get this resolved and put the answer out there for everyone to see. Seems to be quite a few of us out there with this annoying error!




Hi Al_Swearengen,


1. Do you have Visual Studio or Visual C++ installed on your computer?


Method 1:

If you have Visual studio or any other such application you may check if you have the latest updates installed for the application.


Method 2:

You may check if re-registering the msvcrt.dll file assists you resolve the issue -

a. Click on Start and then click on Run.

b. Now you can type the below command (without quotes) -
“Regsvr32 C:\Windows\System32\msvcrt.dll”

c. Once the command is input into the Run field correctly, press Enter.

d. Once the DLL has been registered, you should receive a confirmation in the form of a pop up box. This message will list your newly registered DLL file and confirm that is was successfully registered into the registry.

Method 3:

You may perform a SFC (System File Checker) scan. It will list any issues and will also recover the files if needed –Follow the below steps to perform a SFC Scan -

a.     ClickStart, click All Programs, click Accessories, right-clickCommand Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or clickAllow

b.     Type the following command, and then press ENTER:

sfc /scannow 

A message will appear stating that 'The system scan will begin'. Be patient because the scan may take some time

c.      If any files require a replace SFC will replace them. You may be asked to insert your Win7 DVD for this process to continue

d.     If everything is okay you should, after the scan, see the following message "Windows resource protection did not find any integrity violations" 

e.     After the scan has completed, close the command prompt window, restart the computer and check.

Check the below mentioned link for further guidance on SFC scan -

Hope this helps.
