Re: Regex in a service..

It seems likely that it's not finding the regex DLL.

Remember that services start in a different environment than user 
processes. It's possible, probable in fact, that the paths are different.

As a quick check, copy the regex dll to the system directory (usually 
C:\WINNT\system32). If the service then starts, you know the problem and 
can figure out a better solution (what that is depends a lot on your 
situation).

My personal favorite solution: Add "." at the start of the system path 
and put the DLLs in the same directory as the service.
