MS Windows – Path

Background

No matter how long one works with MS Windows one still stumbles.

Application Install

I have a  new machine and I have been installing quite a few applications and just found out Google Chrome and Mozilla.Org Firefox are no longer working.

 

SysInternals – Process Monitor

Checked Event Viewer, but nothing and so downloaded SysInternals’s Process Monitor and trained it at my google Path.

NameNotFound

Narrow:

NameNotFoundNarrow

 

Explanation:

  1. The give away is that netutils.d.dll, srvcli.dll, wkscli.dll, Samcli.dll can not be found

 

Path

Reviewed Path

Launched OS Command Shell and checked path by issuing “path”

 

PathBefore
Determined that C:\Windows\System32 is missing.

 

Correct

Original Path

AccessedSystemProperties-EditSystemVariable

 

Corrected Path

Placed C:\Windows\System32 squarely in front of everything.

PathEnd

 

SysInternals – Process Monitor – Post Correction

Once changes made, we can see that the effect of the changes:

Screen:

NameNotFoundAlternatePathUsed

 

wkscli.dll:

NameNotFoundAlternatePathUsed-wkscli

 

CreateFile – NAME NOT FOUND

 

CreateFile-NameNotFound

 

CreateFile – SUCCESS

CreateFile-Success

 

Explanation:

  1. Attempt to access wkscli.dll from the local folder failed
  2. Hence, the system accessed via C:\Windows\SysWOW64

 

 

Summary

I know it is a far cry from where we used to be, but the System Path and centralized registry can still be a bit brittle and unforgiving.
