Minor problem: Windows component call failed, unable to load installation package: wbemupgd. dll

Open Add/delete todayProgramTo install several Windows components, the following error occurs:

Unable to load and install the installer: wbemupgd. dll, or the 0centry function cannot be found. contact your system administrator. The specific error code is 0x7e.

So, search, it turns out that in the PATH environment variable, the point pointing to the system32/WBEM directory is missing...

OK .. follow the steps below to solve

My computer -- Property -- Advanced -- environment variable -- in the system variable -- path to see if there are characters pointing to % SystemRoot % \ system32 \ and % SystemRoot % \ system32 \ WBEM, it would be nice if you didn't add the two characters .. example: D: \ windows \ system32; D: \ windows \ system32 \ WBEM;
