;%SystemRoot%;

etc.

Path needs the expanded version of these environment variables.

Will they work if you leave them in the default path (instead of changing to the root of c?

 

[JPJeffery]

Not absolutely sure what you mean. To clarify, I understand that the variables need to hold a valid value but I've demonstrated that they do in the text above.

e.g.

C:\>set systemr
SystemRoot=C:\WINDOWS

Obviously that only shows one, so here's the expansion of all the system variables in the PATH statement:

C:\>set sys
SystemDrive=C:
SystemRoot=C:\WINDOWS

tlcscousin
Yes, again as demonstrated above, if I change the current directory to c:\windows\system32 the commands work - but of course I should have to because that folder is in the path statement.

what strongm neans,
when you type path=>enter in cmd, the variables should be resolved to the values, i.e

%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem
should show as

c:\windows\system32;c:\windows;c:\windows\System32\Wbem

>so here's the expansion

The point is that they are NOT expanded in the PATH statement; doesn't matter that they are expanded anywhere else.

One possible technical reason for this is that the Path value in the Registry has been incorrectly set as REG_SZ instead of REG_EXPAND_SZ (the first is a normal string, the second is a string that, when read from the registry, needs to be expanded) - and the fact that your PATH statement shows the environment variables in their unexpanded state is clear evidence that this is happening. There are a few tools and application installations which have been known to erroneously change the type of the Path value (e.g. doPDF's installer did this for a while until the bug was fixed).

If you have a look at the following key in the registry

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment

and look for Path you will almost cetrainly see that it is of type REG_SZ

Sadly there is no easy way of converting the type of the value. You have to:

1. Copy Path value content
2. Delete the Path value
3. Create a new value named "Path" of type REG_EXPAND_SZ
4. Paste in the value you copied in step 1
5. Restart machine

Ah, I see. Thank you, Gentlemen.

[tlcscousin]

C:\Documents and Settings\Administrator.domain>
would be the default path when you open a command prompt, do the commands work from there without doing the cd\

 

[JPJeffery]

Finally got round to applying the suggested fix from Strongm, and it worked a treat.

Thanks, Strongm.
