I am having a problem reading files, on some systems, when running as
a windows service. The same code, run as an executable works just
fine. On my system it works. On a co-workers it doesn't. Same OS
(2000Pro).

The service is logged on as "LocalSystem".

I've seen similar posts, but I've yet to see an appropriate answer.
The file name is built from DirectoryInfo and FileInfo details, so the
format should be fine.

Hi David,

First try to use the backward slash (\) as a path separator. The forward
slash character is not typical for the Windows platform and can cause
problems.

Good point, but changing that didn't help. Still craps out as a
service, but not executable.

The problem is most likely caused by the CanonicalizePath method. Do MSDN
docs say something about any specific requirements for this method?

What are the permissions for the file
"C:\Creo\FeatureLicensing\Database\demo.cvf.xml"? Does LocalSystem have
access?

Generally LocalSystem (which shows up as SYSTEM in explorer's ACL
editor) has full access, but it's possible for that access to be
removed. When you run the code as a standard executable, it runs under
the logged on user's identity, who might have access rights to the file
that SYSTEM does not have.

Then again, I'd expect a different error in that case - I'm just
guessing here.

Update/solution:

Finally tracked it down. Briefly, the System TMP environment variable
was poorly formed!

In detail:

I was calling XmlSerializer() which, if we follow the stack trace,
needs to compile code, presumably based on the object type I pass to
it. Way down in the bowels of the stack it needs to make a temporary
file to write to. It must be getting the temporary path through a
similar call as Path.GetTempFileName(). If the TEMP/TMP environment
variable is BAD, the call fails and all you get is "The given path's
format is not supported.", which is refering to the internal temporary
name, not any name I was using.

The issue only presented itself, because when run under a user account
it uses the envirnment variable set under the "User variable for xxx"
section of the "Environment Variables" dialog. When running as a
service, it uses the settings under the "System variables" section.
What was happening was the System TMP variable was badly formed;
"C:\temp;C:\WINNT\TEMP". Someone had mistakenly set the variable as if
it was a path list, rather than a discrete directory path. Changing
the variable back to "C:\WINNT\TEMP" fixed the problem.

It's unfortunate that the .NET framework is relying internally on a
user configuration setting that could be invalid. To be fair, I had
other software behave poorly when I changed my TMP variable to be bad,
in testing the scenario.
