Hi,
1.
Were there any changes made to your computer before the issue occurred?
Snapin launcher is a process wherein the relevant executable file is triggered. For example, to open the Command prompt window we just click on Command Prompt under Start/All Programs/Accessories
but in the background the snapin process triggers cmd.exe application and this in turn opens the Command prompt window.
I would suggest you to follow few troubleshooting steps from the articles below and check if that help you in fixing the
issue on your computer.
Method:
You can try to run SFC scan to find missing or corrupt files that may be causing this issue.
System File Checker (SFC) checks that all Windows 7 system files are intact and not corrupted, changed, or damaged.
a.
Click Start, click All Programs, click Accessories, right-click Command Prompt, and select Run as Administrator.
b.
Click Continue or supply Administrator credentials if prompted.
c.
In the Command Prompt window type the following, and press Enter:
sfc /scannow
d.
You should see the following on-screen message:
Beginning the system scan. This process will take some time.
Beginning verification phase of system scan.
Verification % complete.
e.
Once the scan has completed, test to see whether the issue that you are experiencing is resolved or not.
